* Small improvements to time estimation.
* Temporarily disable NTP time check by default.
* generate proofs on newly-created state
* report only missed steps after first block
* dont report skipped if not signer

* Ordering -> AtomicOrdering
* reinstate warning now that spam is reduced
* flush pending transition changes when necessary
* ensure epochs aren't re-zoomed on every block
* Clarify function name
Function checks if sealing is currently underway, not to be confused
with checking whether the engine performs internal sealing.
* Error when work called on internal sealing engine
* Error submitting work for internal sealing engine
* Fix inverted bool and style grumbles
* Add can_produce_work_package to TestMinerService
* Error when setting engine signer on PoW chain
* Unit tests for engine signing
Setting engine signer should fail if chain does not seal internally
or client lacks account provider.
* Tweak TestMinerService

* do more validation of imported headers in light client
* generalize informant with traits
* informant implementation for light client
* make comment into TODO
* fix broken test
* disable full checking of headers in light client in sync tests
* Order by id instead of hash.
* Minimal gas price bump.
* Avoid to construct oversized transaction packets.
* Fix RPC.
* Never construct oversized transactions packet.
* Never construct oversized packets.
This is a huge change, which includes some changes to replace code that
originally cloned to reuse allocations instead. The updated
`elastic-array` crate renames its consuming `Vec`-conversion method to
`into_vec`, which means that I can do a simple
`sed -i 's/to_vec/into_vec/'` and then fix the compilation errors.
This commit is probably a minor performance win and definitely a
significant readability win.
