faeb666536 util: Add CHECK_NONFATAL and use it in src/rpc (MarcoFalke)
Pull request description:
Fixes#17181
Currently, we use `assert` in RPC code to document logic and code assumptions. However, it seems a bit extreme to abort all of Bitcoin Core on an assert failure in one of the RPC threads. I suggest to replace all `assert`s with a macro `CHECK_NONFATAL(condition)` that throws a runtime error when the condition evaluates to `false`. That runtime error will then be returned to the rpc caller and will include instructions to report the error to our issue tracker.

Added are:
* Vector(arg1,arg2,arg3,...) constructs a vector with the specified
arguments as elements. The vector's type is derived from the
arguments. If some of the arguments are rvalue references, they
will be moved into place rather than copied (which can't be achieved
using list initialization).
* Cat(vector1,vector2) returns a concatenation of the two vectors,
efficiently moving elements when relevant.
Vector generalizes (and replaces) the Singleton function in
src/descriptor.cpp, and Cat replaces the Cat function in bech32.cpp

Pull request description:
As suggested here: https://github.com/bitcoin/bitcoin/pull/16800#issuecomment-531605482.
This moves the Span parsing functions out of the descriptor module, making them more easily usable for other parsers (in particular, in preparation for miniscript parsing).

7fb886b1b1 [moveonly] Split glibc sanity_test_fdelt out (Ben Woosley)
Pull request description:
SmartOS FD_ZERO is implemented in a way that requires
an external declaration of memcpy. We can not simply
include cstring in the existing file because
sanity_test_memcpy is attempting to replace memcpy.
Instead split glibc_sanity into fdelt and memcpy files,
and include <cstring> in glibc_sanity/fdelt.cpp.

Pull request description:
This PR compresses the `CWallet` chain of inheritance from 5 classes to 3 classes. `CBasicKeyStore` is renamed to `FillableSigningProvider` and some parts of it (the watchonly parts) are moved into `CWallet`. `CKeyStore` and `CCrypoKeyStore` are completely removed. `CKeyStore`'s `Have*` functions are moved into `SigningProvider` and the `Add*` moved into `FillableSigningProvider`, thus allowing it to go away entirely. `CCryptoKeyStore`'s functionality is moved into `CWallet`. The new inheritance chain is:
```
SigningProvider -> FillableSigningProvider -> CWallet
```
`SigningProvider` now is the class the provides keys and scripts and indicates whether keys and scripts are present. `FillableSigningProvider` allows keys and scripts to be added to the signing provider via `Add*` functions. `CWallet` handles all of the watchonly stuff (`AddWatchOnly`, `HaveWatchOnly`, `RemoveWatchOnly` which were previously in `CKeyStore`) and key encryption (previously in `CCryptoKeyStore`).
Implements the 2nd [prerequisite](https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Class-Structure-Changes#cwallet-subclass-stack) from the wallet restructure.

Pull request description:
This adds a limited implementation of `HKDF` (defined by rfc5869) that supports only HMAC-SHA256 and length output of 32 bytes (will be required for v2 transport protocol).
This PR also includes a method to negate a private key which is useful to enforce public keys starting with 0x02 (or 0x03) (a requirement for the v2 transport protocol). The new `CKey::Negate()` method is pretty much a wrapper around `secp256k1_ec_privkey_negate()`.
Including tests.
This is a subset of #14032 and a pre-requirement for the v2 transport protocol.

This work is prerequisite to attaching thread names to log lines and deadlock
debug utilities. This code allows setting of an "internal" threadname per
thread on platforms where thread_local is available.
This commit also moves RenameThread() out of a more general module and adds a
numeric suffix to disambiguate between threads with the same name. It
explicitly names a few main threads using the new util::ThreadRename().
418d3230f8 Resolve the checkpoints <-> validation CD. (251)
Pull request description:
This pull request attempts to resolve the `checkpoints -> validation -> checkpoints` circular dependency.
The circular dependency is resolved by moving the `CheckPoints::GetLastCheckpoint(const CCheckpointData& data)` function to `validation.cpp` where it used exclusively by the private function `ContextualCheckBlockHeader(const CBlockHeader& block, CValidationState& state, const CChainParams& params, const CBlockIndex* pindexPrev, int64_t nAdjustedTime)`.

Pull request description:
This introduces a new BlockFilterIndex class, which is required for BIP 157 support.
The index is uses the asynchronous BaseIndex infrastructure driven by the ValidationInterface callbacks. Filters are stored sequentially in flat files and the disk location of each filter is indexed in LevelDB along with the filter hash and header. The index is designed to ensure persistence of filters reorganized out of the main chain to simplify the BIP 157 net implementation.
Stats (block height = 565500):
- Syncing the index from scratch takes 45m
- Total index size is 3.8 GiB

psbt.cpp definitions except for AnalyzePSBT are used by the wallet and need to
be linked into the wallet binary. AnalyzePSBT is an exception in that it is not
used by the wallet, and depends on node classes like CCoinsViewCache, and on
node global variables like nBytesPerSigOp.
So AnalyzePSBT is more at home in libbitcoin_server than libbitcoin_common, and
in any case needs to be defined in a separate object file than other PSBT
utilities, to avoid dragging link dependencies on node functions and global
variables into the wallet.
Moves the following wallet load functions to a new wallet/load unit in
the libbitcoin_wallet library. All other functions in wallet/init remain
in libbitcoin_server:
- `VerifyWallets`
- `LoadWallets`
- `StartWallets`
- `FlushWallets`
- `StopWallets`
- `UnloadWallets`
Adds the following util units and adds them to libbitcoin_util:
- `util/url.cpp` takes `urlDecode` from `httpserver.cpp`
- `util/error.cpp` takes `TransactionErrorString` from
`node/transaction.cpp` and `AmountHighWarn` and `AmountErrMsg` from
`ui_interface.cpp`
- `util/fees.cpp` takes `StringForFeeReason` and `FeeModeFromString` from `policy/fees.cpp`
- `util/rbf.cpp` takes `SignalsOptInRBF` from `policy/rbf.cpp`
- 'util/validation.cpp` takes `FormatStateMessage` and `strMessageMagic` from 'validation.cpp`
Moves the following units into libbitcoin_util or libbitcoin_common
since they are required by multiple libraries:
- bloom
- interfaces/handler
- merkleblock
- outputtype
rpc/rawtransaction.cpp moves to libbitcoin_server since it should not be
accessed by non-node libraries. The utility following utility methods
move to their own unit rpc/rawtransaction_util since they need to be
accessed by non-node libraries:
- `ConstructTransaction`
- `TxInErrorToJSON`
- `SignTransaction`
Moves the following utility methods to rpc/util and moves that unit to
libbitcoin_common so they can be accessed by all libraries.
- `RPCTypeCheck`
- `RPCTypeCheckArgument`
- `RPCTypeCheckObj`
- `AmountFromValue`
- `ParseHashV``ParseHashO`
- `ParseHexV`
- `ParseHexO`
- `HelpExampleCli`
- `HelpExampleRpc`
This moves the following policy settings functions and globals to a new
src/policy/settings unit in lib_server:
- `incrementalRelayFee`
- `dustRelayFee`
- `nBytesPerSigOp`
- `fIsBareMultisigStd`
These settings are only required by the node and should not be accessed
by other libraries.
CheckTransaction is a context-free function that does not require access
to the blockchain or mempool. Move it from src/consensus/tx_verify in
lib_server to a new unit src/consensus/tx_check in lib_consensus so that
it can be called by non-server libraries.

Pull request description:
Refactor the analyzepsbt RPC into (1) an AnalyzePSBT function, which returns
its output as a new strongly-typed PSBTAnalysis struct, and (2) a thin wrapper
which converts the struct into a UniValue for RPC use.
----
As with my previous refactoring PR, I need this because I am creating a dependency on this code from the GUI. Per discussion in #bitcoin-core-dev on IRC, since we don't want to create a dependency on UniValue in anything outside RPC, I introduced some new structs to hold the info we get when analyzing a PSBT. For the field types, I used whatever types are already used internally for this data (e.g. CAmount, CFeeRate, CKeyID), and only convert to int/string etc. in the wrapper.
