c6e2c31c55 rpc: unhide waitfor{block,newblock,blockheight} (Sjors Provoost)
0786b7509a rpc: add optional blockhash to waitfornewblock (Sjors Provoost)
Pull request description:
The `waitfornewblock` is inherently racy as the tip may have changed since the last RPC call, and can even change during initial processing of this call.
Add an optional `blockhash` argument so the caller can specify their current tip. Return immediately if our tip is different.
I've made it fail if `LookupBlockIndex` fails. This should never happen if the user got the block hash from our RPC in the first place.
Finally, the `waitfor{block,newblock,blockheight}` RPC methods are no longer hidden in `help`:
- the changes in #30409 ensured these methods _could_ work in the GUI
- #31785 removed the guards that prevented GUI users from using them
- this PR makes `waitfornewblock` reliable
So there's no more reason to hide them.

Note that we unfortunately can't use a scripted diff here, as the
`sha256` symbol is also used for other instances (e.g. as function
in hashlib, or in the `UTXO` class in p2p_segwit.py).
Since the previous commit, CBlockHeader/CBlock object calls to the
methods `.rehash()` and `.calc_sha256()` are effectively no-ops
if the returned value is not used, so we can just remove them.
In the functional tests there are lots of cases where we assert != which
this new util will replace, we also are adding the imports and the new assertion

fa0232a3e0 test: add validation for gettxout RPC response (Alfonso Roman Zubeldia)
Pull request description:
Added a new test in `test/functional/rpc_blockchain.py` to validate the gettxout RPC response. This new test ensures all response elements are verified, including `bestblock`, `confirmations`, `value`, `coinbase`, and `scriptPubKey` details.
Also renamed the method `get_scriptPubKey` from `test/functional/test_framework/wallet.py` to the modern name `get_output_script` as suggested by maflcko (https://github.com/bitcoin/bitcoin/pull/30226#discussion_r1925491846)

This avoids low-level log errors that are supposed to only occur when
there is an actual problem with the block on disk missing unexpectedly,
but not in the case where the block and/or undo data are expected not to be there.
It changes behavior such that in the first case (block index indicates
data is available but retrieving it fails) an error is thrown.
It also adjusts a functional tests that tried to simulate not
having undo data (but having block data) by deleting the undo file.
This situation should occur reality because block and undo data are pruned together.
Instead, test this situation with a block that hasn't been connected.
This currently has no effect due to fPowNoRetargeting,
except for the getnetworkhashps when called with -1.
It will when the next commit enforces the timewarp attack mitigation on regtest.

By throwing a custom exception from `Univalue::checkType` (instead of a plain
std::runtime_error) and catching it on the RPC server request handler.
So we properly return RPC_TYPE_ERROR (-3) on arg type errors and
not the general RPC_MISC_ERROR (-1).
f663b43df0 QA: rpc_blockchain: Test output of getblock verbosity 0, False, and True (Luke Dashjr)
Pull request description:
Currently getblock's "verbosity" is documented as a NUM, though it has a fallback to Boolean for the (deprecated?) "verbose" alias.
Since we've been doing more generic type-checking on RPC stuff, I think it would be a good idea to actually test the Boolean values work.
I didn't see an existing test for verbosity=0, so this adds that too.

In order to prevent memory DoS, we must ensure that we don't accept a new
header into memory until we've performed anti-DoS checks, such as verifying
that the header is part of a sufficiently high work chain. This commit adds a
new argument to AcceptBlockHeader() so that we can ensure that all call-sites
which might cause a new header to be accepted into memory have to grapple with
the question of whether the header is safe to accept, or needs further
validation.
This patch also fixes two places where low-difficulty-headers could have been
processed without such validation (processing an unrequested block from the
network, and processing a compact block).

for test code.

fd826130a0 rpc: move softfork info from getblockchaininfo to getdeploymentinfo (Anthony Towns)
Pull request description:
The aim of this PR is to improve the ability to monitor soft fork status. It first moves the softfork section from getblockchaininfo into a new RPC named getdeploymentinfo, which is then also able to query the status of forks at an arbitrary block rather than only at the tip. In addition, bip9 status is changed to indicate the status of the given block, rather than just for the next block, and an additional field is included to indicate whether each block in the signalling period signaled.

On a period boundary, getdeploymentinfo (and previously getblockchaininfo)
would report the status and statistics for the next block rather than
the current block. Change this to always report the status/statistics
of the current block, but add status-next to report the status for the
next block.
The previous diff touched most files in ./test/, so bump the headers to
avoid having to touch them again for a bump later.
