Parity Ethereum 2.1.10-stable

Parity-Ethereum 2.1.10-stable is an important release that introduces Constantinople fork at block 7080000 on Mainnet.

This release also contains a fix for chains using AuRa + EmptySteps. Read carefully if this applies to you.
If you have a chain withempty_steps already running, some blocks most likely contain non-strict entries (unordered or duplicated empty steps). In this releasestrict_empty_steps_transition is enabled by default at block 0 for any chain with empty_steps.
If your network uses empty_steps you must:

• plan a hard fork and change strict_empty_steps_transition to the desire fork block
• update the clients of the whole network to 2.2.5-beta / 2.1.10-stable.

If for some reason you don't want to do this please setstrict_empty_steps_transition to 0xfffffffff to disable it.

Upgrading is strongly recommended.

The full list of included changes:

• Backports for stable 2.1.10 (#10046)
  • Bump stable to 2.1.10 (#10046)
  • RPC: parity_getBlockReceipts (#9527)
    • Block receipts RPC.
    • Use lazy evaluation of block receipts (ecrecover).
    • Optimize transaction_receipt to prevent performance regression.
    • Add block & transaction receipt tests.
    • Fix conversion to block id.
  • Update a few parity-common dependencies (#9663)
    • revert update of ethereum/tests
    • better reporting of network rlp errors
    • Use rlp 0.3.0-beta.1
    • fix util function get_dummy_blocks
    • Already a Vec
    • encode_list returns vec already
  • Fix empty steps (#9939)
    • Prevent sending empty step message twice
    • Prevent sending empty step and then block in the same step
    • Don't accept double empty steps
    • Do basic validation of self-sealed blocks
  • Strict empty steps validation (#10041)
    • Enables strict verification of empty steps - there can be no duplicates and empty steps should be ordered inside the seal.
    • Note that authorities won't produce invalid seals after #9939, this PR just adds verification to the seal to prevent forging incorrect blocks and potentially causing consensus issues.
    • This features is enabled by default so any AuRa + EmptySteps chain should set strict_empty_steps_transition fork block number in their spec and upgrade to v2.2.5-beta or v2.1.10-stable.
