Merge #16060: Bury bip9 deployments
e78aaf41f4[docs] Add release notes for burying bip 9 soft fork deployments (John Newbery)8319e738f9[tests] Add coverage for the content of getblockchaininfo.softforks (James O'Beirne)0328dcdcfc[Consensus] Bury segwit deployment (John Newbery)1c93b9b31c[Consensus] Bury CSV deployment height (John Newbery)3862e473f0[rpc] Tidy up reporting of buried and ongoing softforks (John Newbery) Pull request description: This hardcodes CSV and segwit activation heights, similar to the BIP 90 buried deployments for BIPs 34, 65 and 66. CSV and segwit have been active for over 18 months. Hardcoding the activation height is a code simplification, makes it easier to understand segwit activation status, and reduces technical debt. This was originally attempted by jl2012 in #11398 and again by me in #12360. ACKs for top commit: ajtowns: ACKe78aaf41f4; checked diff to previous acked commit, checked tests still work ariard: ACKe78aaf4, check diff, run the tests again and successfully activated csv/segwit heights on mainnet as expected. MarcoFalke: ACKe78aaf41f4(still didn't check if the mainnet block heights are correct, but the code looks good now) Tree-SHA512: 7e951829106e21a81725f7d3e236eddbb59349189740907bb47e33f5dbf95c43753ac1231f47ae7bee85c8c81b2146afcdfdc11deb1503947f23093a9c399912

Low-level RPC changes
|
||||
----------------------
|
||||
|
||||
- Soft fork reporting in the `getblockchaininfo` return object has been
|
||||
updated. For full details, see the RPC help text. In summary:
|
||||
- The `bip9_softforks` sub-object is no longer returned
|
||||
- The `softforks` sub-object now returns an object keyed by soft fork name,
|
||||
rather than an array
|
||||
- Each softfork object in the `softforks` object contains a `type` value which
|
||||
is either `buried` (for soft fork deployments where the activation height is
|
||||
hard-coded into the client implementation), or `bip9` (for soft fork deployments
|
||||
where activation is controlled by BIP 9 signaling).
|
||||
|
||||
- `getblocktemplate` no longer returns a `rules` array containing `CSV`
|
||||
and `segwit` (the BIP 9 deployments that are currently in active state).
