* Do not skip snapshots further away than 30k block from the highest block seen
Currently we look for peers that seed snapshots that are close to the highest block seen on the network (where "close" means withing 30k blocks). When a node starts up we wait for some time (5sec, increased here to 10sec) to let peers connect and if we have found a suitable peer to sync a snapshot from at the end of that delay, we start the download; if none is found and --warp-barrier is used we stall, otherwise we start a slow-sync.
When looking for a suitable snapshot, we use the highest block seen on the network to check if a peer has a snapshot that is within 30k blocks of that highest block number. This means that in a situation where all available snapshots are older than that, we will often fail to start a snapshot at all. What's worse is that the longer we delay starting a snapshot sync (to let more peers connect, in the hope of finding a good snapshot), the more likely we are to have seen a high block and thus the more likely we become to accept a snapshot.
This commit removes this comparison with the highest blocknumber criteria entirely and picks the best snapshot we find in 10sec.
* lockfile
* Add a `ChunkType::Dupe` variant so that we do not disconnect a peer if they happen to send us a duplicate chunk (just ignore the chunk and keep going)
Resolve some documentation todos, add more
* tweak log message
* Don't warp sync twice
Check if our own block is beyond the given warp barrier (can happen after we've completed a warp sync but are not quite yet synced up to the tip) and if so, don't sync.
More docs, resolve todos.
Dial down some `sync` debug level logging to trace
* Avoid iterating over all snapshot block/state hashes to find the next work item
Use a HashSet instead of a Vec and remove items from the set as chunks are processed. Calculate and store the total number of chunks in the `Snapshot` struct instead of counting pending chunks each time.

Note: Adds libc as a dependency to util/network
* Use assert-matches for more readable tests
* Fix Wording and consistency
Unpack errors and check for io::ErrorKind::InvalidInput and return our own AddressParse error. Remove the foreign link to std::net::AddrParseError and add an `impl From` for that error. Test parsing properly.
* Consolidate crypto functionality in `ethcore-crypto`.
- Move `ecdh`/`ecies` modules to `ethkey`.
- Refactor `ethcore-crypto` to use file per module.
- Replace `subtle` with `ethcore_crypto::is_equal`.
- Add `aes_gcm` module to `ethcore-crypto`.
* Rename `aes::{encrypt,decrypt,decrypt_cbc}` ...
... to `aes::{encrypt_128_ctr,decrypt_128_ctr,decrypt_128_cbc}`.

* Replace Rlp with UntrustedRlp in views, explicity unwrap with expect
First pass to get it to compile. Need to figure out whether to do this or to propogate Errors upstream, which would require many more changes to dependent code. If we do this way we are assuming that the views are always used in a context where the rlp is trusted to be valid e.g. when reading from our own DB. So need to fid out whether views are used with data received from an untrusted (e.g. extrernal peer).
* Remove original Rlp impl, rename UntrustedRlp -> Rlp
* Create rlp views with view! macro to record debug info
Views are assumed to be over valid rlp, so if there is a decoding error we record where the view was created in the first place and report it in the expect
* Use $crate in view! macro to avoid import, fix tests
* Expect valid rlp in decode functions for now
* Replace spaces with tabs in new file
* Add doc tests for creating views with macro
* Update rlp docs to reflect removing of UntrustedRlp
* Replace UntrustedRlp usages in private-tx merge
* Filter-out nodes.json
* network: sort node table nodes by failure ratio
* network: fix node table tests
* network: fit node failure percentage into buckets of 5%
