beta backports for 2.0.3 (#9229)

* parity-version: bump beta to 2.0.2

* remove ssl from dockerfiles, closes #8880 (#9195)

* snap: remove ssl dependencies from snapcraft definition (#9222)

* parity-version: bump beta to 2.0.3

* Remove all dapp permissions related settings (#9120)

* Completely remove all dapps struct from rpc

* Remove unused pub use

* Address grumbles

* Address grumbles

* Fix tests

* Check if synced when using eth_getWork (#9193) (#9210)

* Check if synced when using eth_getWork (#9193)

* Don't use fn syncing

* Fix identation

* Fix typo

* Don't check for warping

* rpc: avoid calling queue_info twice on eth_getWork

* Fix potential as_usize overflow when casting from U256 in miner (#9221)

* Allow old blocks from peers with lower difficulty (#9226)

Previously we only allow downloading of old blocks if the peer
difficulty was greater than our syncing difficulty. This change allows
downloading of blocks from peers where the difficulty is greater then
the last downloaded old block.

* Update Dockerfile (#9242)

* Update Dockerfile

fix Docker build

* fix dockerfile paths: parity -> parity-ethereum (#9248)

* Propagate transactions for next 4 blocks. (#9265)

Closes #9255 

This PR also removes the limit of max 64 transactions per packet, currently we only attempt to prevent the packet size to go over 8MB. This will only be the case for super-large transactions or high-block-gas-limit chains.

Patching this is important only for chains that have blocks that can fit more than 4k transactions (over 86M block gas limit)

For mainnet, we should actually see a tiny bit faster propagation since instead of computing 4k pending set, we only need `4 * 8M / 21k = 1523` transactions.

Running some tests on `dekompile` node right now, to check how it performs in the wild.

* Update tobalaba.json (#9313)

* Fix load share (#9321)

* fix(light_sync): calculate `load_share` properly

* refactor(api.rs): extract `light_params` fn, add test

* style(api.rs): add trailing commas

* ethcore: fix pow difficulty validation (#9328)

* ethcore: fix pow difficulty validation

* ethcore: validate difficulty is not zero

* ethcore: add issue link to regression test

* ethcore: fix tests

* ethcore: move difficulty_to_boundary to ethash crate

* ethcore: reuse difficulty_to_boundary and boundary_to_difficulty

* ethcore: fix grumbles in difficulty_to_boundary_aux

* Light client `Provide default nonce in transactions when it´s missing` (#9370)

* Provide `default_nonce` in tx`s when it´s missing

When `nonce` is missing in a `EthTransaction` will cause it to fall in
these cases provide `default_nonce` value instead!

* Changed http:// to https:// on Yasm link (#9369)

Changed http:// to https:// on Yasm link in README.md

* Provide `default_nonce` in tx`s when it´s missing

When `nonce` is missing in a `EthTransaction` will cause it to fall in
these cases provide `default_nonce` value instead!

* Address grumbles

* ethcore: kovan: delay activation of strict score validation (#9406)

* Better support for eth_getLogs in light mode (#9186)

* Light client on-demand request for headers range.

* Cache headers in HeaderWithAncestors response.

Also fulfills request locally if all headers are in cache.

* LightFetch::logs fetches missing headers on demand.

* LightFetch::logs limit the number of headers requested at a time.

* LightFetch::logs refactor header fetching logic.

* Enforce limit on header range length in light client logs request.

* Fix light request tests after struct change.

* Respond to review comments.

* Add update docs script to CI (#9219)

* Add update docs script to CI

Added a script to CI that will use the jsonrpc tool to update rpc
documentation then commit and push those to the wiki repo.

* fix gitlab ci lint

* Only apply jsonrpc docs update on tags

* Update gitlab-rpc-docs.sh

* Copy correct parity repo to jsonrpc folder

Copy correct parity repo to jsonrpc folder before attempting to build docs since the CI runner clones the repo as parity and not parity-ethereum.

* Fix JSONRPC docs CI job

Update remote config in wiki repo before pushing changes using a github
token for authentication. Add message to wiki tag when pushing changes.
Use project directory to correctly copy parity code base into the
jsonrpc repo for doc generation.

 Parity's goal is to be the fastest, lightest, and most secure Ethereum client. We are developing Parity using the sophisticated and cutting-edge Rust programming language. Parity is licensed under the GPLv3, and can be used for all your Ethereum needs.
 
-Parity comes with a built-in wallet. To access [Parity Wallet](http://web3.site/) simply go to http://web3.site/ (if you don't have access to the internet, but still want to use the service, you can also use http://127.0.0.1:8180/). It includes various functionality allowing you to:
-
-- create and manage your Ethereum accounts;
-- manage your Ether and any Ethereum tokens;
-- create and register your own tokens;
-- and much more.
+From Parity Ethereum client version 1.10.0, the User Interface (UI) is accessible in a separate application called Parity UI. To keep using the UI in the browser (deprecated), [follow these steps](https://wiki.parity.io/FAQ-Basic-Operations,-Configuration,-and-Synchronization#the-parity-ui-application-isnt-working-the-way-i-want).
 
 By default, Parity will also run a JSONRPC server on `127.0.0.1:8545` and a websockets server on `127.0.0.1:8546`. This is fully configurable and supports a number of APIs.

-# Parity Dapps (JS-glue)
-
-Code generator to simplify creating a built-in Parity Dapp
-
-# How to create new builtin Dapp.
-1. Clone this repository.
-
-   ```bash
-   $ git clone https://github.com/paritytech/parity.git
-   ```
-
-1. Create a new directory for your Dapp. (`./myapp`)
-
-   ```bash
-   $ mkdir -p ./parity/dapps/myapp/src/web
-   ```
-
-1. Copy your frontend files to `./dapps/myapp/src/web` (bundled ones)
-
-   ```bash
-   $ cp -r ./myapp-src/* ./parity/dapps/myapp/src/web
-   ```
-
-1. Instead of creating `web3` in your app. Load (as the first script tag in `head`):
-
-   ```html
-   <script src="/parity-utils/inject.js"></script>
-   ```
-
-   The `inject.js` script will create global `web3` instance with proper provider that should be used by your dapp.
-
-1. Create `./parity/dapps/myapp/Cargo.toml` with you apps details. See example here: [parity-status Cargo.toml](https://github.com/paritytech/parity-ui/blob/master/status/Cargo.toml).
-
-   ```bash
-   $ git clone https://github.com/paritytech/parity-ui.git
-   $ cd ./parity-ui/
-   $ cp ./home/Cargo.toml ../parity/dapps/myapp/Cargo.toml
-   $ cp ./home/build.rs ../parity/dapps/myapp/build.rs
-   $ cp ./home/src/lib.rs ../parity/dapps/myapp/src/lib.rs
-   $ cp ./home/src/lib.rs.in ../parity/dapps/myapp/src/lib.rs.in
-   # And edit the details of your app
-   $ vim ../parity/dapps/myapp/Cargo.toml # Edit the details
-   $ vim ./parity/dapps/myapp/src/lib.rs.in # Edit the details
-   ```
-# How to include your Dapp into `Parity`?
-1. Edit `dapps/Cargo.toml` and add dependency to your application (it can be optional)
-
-   ```toml
-   # Use git repo and version
-   parity-dapps-myapp = { path="./myapp" }
-   ```
-
-1. Edit `dapps/src/apps.rs` and add your application to `all_pages` (if it's optional you need to specify two functions - see `parity-dapps-wallet` example)
-
-1. Compile parity.
-
-   ```bash
-   $ cargo build --release # While inside `parity`
-   ```
-
-1. Commit the results.
-
-   ```bash
-   $ git add myapp && git commit -am "My first Parity Dapp".
-   ```

+## Parity [v1.10.1](https://github.com/paritytech/parity/releases/tag/v1.10.1) (2018-04-17)
+
+Parity 1.10.1 is a bug-fix release to improve performance and stability. Among other changes, you can now use `--warp-barrier [BLOCK]` to specify a minimum block number to `--warp` to. This is useful in cases where clients restore to outdated snapshots far behind the latest chain head.

+
+## Parity [v1.10.0](https://github.com/paritytech/parity/releases/tag/v1.10.0) (2018-03-22)
+
+This is the Parity 1.10.0-beta release! Cool!
+
+### Disabling the Parity Wallet
+
+The **Parity Wallet (a.k.a. "UI") is now disabled by default**. We are preparing to split the wallet from the core client.
+
+To reactivate the parity wallet, you have to run Parity either with `parity --force-ui` (not recommended) or `parity ui` (deprecated) from the command line. Or, if you feel super fancy and want to test our pre-releases of the stand-alone electron wallet, head over to the [Parity-JS repositories and check the releases](https://github.com/Parity-JS/shell/releases).
+
+Further reading:

+- [Docs: How to customize Parity UI?](https://wiki.parity.io/FAQ-Customize-Parity-UI.html)
+- [Github: Parity-JS](https://github.com/parity-js)
+
+### Introducing the Wasm VM
+
+We are excited to announce support for **Wasm Smart Contracts on Kovan network**. The hard-fork to activate the Wasm-VM will take place on block `6_600_000`.
+
+To enable Wasm contracts on your custom network, just schedule a `wasmActivationTransition` at your favorite block number (e.g., `42`, `666`, or `0xbada55`). To hack your first Wasm smart contracts in Rust, have a look at the [Parity Wasm Tutorials](https://github.com/paritytech/pwasm-tutorial).

+
+### Empty step messages in PoA
+
+To **reduce blockchain bloat, proof-of-authority networks can now enable _empty step messages_ which replace empty blocks**. Each step message will be signed and broadcasted by the issuing authorities, and included and rewarded in the next non-empty block.
+
+To enable empty step messages, set the `emptyStepsTransition` to your favorite block number. You can also specify a maximum number of empty steps with `maximumEmptySteps` in your chain spec.
+
+### Other noteworthy changes
+
+We removed the old database migrations from 2016. In case you upgrade Parity from a really, really old version, you will have to reset your database manually first with `parity <options> db kill`.
+
+We fixed  DELEGATECALL `from` and `to` fields, see [#7166](https://github.com/paritytech/parity/issues/7166).
+
+We reduced the default USD per transaction value to 0.0001. Thanks, @MysticRyuujin!
+
+The Musicoin chain is now enabled with Byzantium features starting at block `2_222_222`.

+## Parity [v1.9.0](https://github.com/paritytech/parity/releases/tag/v1.9.0) "Velocity" (2018-01-25)
+
+We are happy to announce our newest Parity 1.9 release. Among others, it enables the following features:
+
+- It integrates the fully reworked Parity Wallet and DApps browser (a.k.a. "UI 2.0", [#6819](https://github.com/paritytech/parity/pull/6819)).
+- It enables devp2p snappy compression ([#6683](https://github.com/paritytech/parity/pull/6683)).
+- AuRa Proof-of-Authority chains now disable uncles by default ([#7006](https://github.com/paritytech/parity/pull/7006)). Existing PoA chains can go through a "maximum uncle count transition" to achieve more stability ([#7196](https://github.com/paritytech/parity/pull/7196)).
+- Added Expanse's Byzantium hard-fork ([#7463](https://github.com/paritytech/parity/pull/7463)).
+- Added support for Ellaism chain ([#7222](https://github.com/paritytech/parity/pull/7222)).
+
+Further, users upgrading from 1.8 should acknowledge the following changes:
+
+- Fixed DELEGATECALL's from/to field ([#7568](https://github.com/paritytech/parity/pull/7568)).
+- Set zero nonce and gas price for calls by default ([#6954](https://github.com/paritytech/parity/pull/6954)).
+- Create pending blocks with all transactions from the queue ([#6942](https://github.com/paritytech/parity/pull/6942)).
+- Remove RPC parameter leniency now that Mist formats correctly ([#6651](https://github.com/paritytech/parity/pull/6651)). Parity stops accepting decimal-formatted block numbers and stops parsing the empty string as empty bytes.
+- Public nodes do not support the user interface anymore. If you are running a public node, please stay on the 1.8 branch of the stable releases.
+
+Additional noteworthy changes:
+
+- `ethstore` and `ethkey` have been significantly improved ([#6961](https://github.com/paritytech/parity/pull/6961)):
+  - `ethstore` now supports brute forcing pre-sale wallets given a password list for recovery.
+  - `ethkey` now supports multi-threaded generation of prefix-matching addresses.
+  - `ethkey` now supports prefix-matching brain wallets.
+  - `ethkey` now supports brain-wallets recovery-phrases lookup. This helps to find a correct phrase if you know the address you want to get yet you made a typo backing the phrase up, or forgot a word.
