Add support for the optional "pf_invalid" out parameter (which allows the caller
to detect decoding failures) to the std::string versions of DecodeBase32 and
DecodeBase64. The char* versions already have this feature.

Also, rename all uses of pfInvalid to pf_invalid to match style guidelines.

Split up DecodePSBT, which both decodes base64 and then deserializes a
PartiallySignedTransaction, into two functions: DecodeBase64PSBT, which retains
the old behavior, and DecodeRawPSBT, which only performs the deserialization.

Add a test for base64 decoding failure.

Factor out a new BroadcastTransaction function, performing the core work of the
sendrawtransaction rpc, so that it can be used from the GUI code. Move it from
src/rpc/ to src/node/.

Move non-wallet PSBT code to src/psbt.{h,cpp}, and PSBT wallet code to
src/wallet/psbtwallet.{h,cpp}. This commit contains only code movement (and
adjustments to includes and Makefile.am.)

After refactoring general-purpose PSBT and transaction code out of RPC code,
for use in the GUI, it's no longer appropriate to throw exceptions. Instead we
now return bools for success, and take an output parameter for an error object.
We still use JSONRPCError() for the error objects, since only RPC callers
actually care about the error codes.

Remove the op== on PartiallySignedTransaction, which only checks that the
CTransactions are equal. Instead, check this directly in Merge, and return
false if the CTransactions are not equal (so the PSBTs cannot be merged.)

Refactor the new CombinePSBT, FinalizePSBT, and FinalizeAndExtractPSBT
general-purpose functions out of the combinepsbt and finalizepsbt RPCs,
for use in the GUI code.

5039e4b Remove unnecessary const_cast (Julian Fleischer)

Pull request description:

  The const_cast

  ```C++
  CBlock &block = const_cast<CBlock&>(chainparams.GenesisBlock());
  ```

  is not necessary as all the functions invoked form this block receive a `const CBlock&` anyway. Simply add the `const` to `block`:

  ```C++
  const CBlock& block = chainparams.GenesisBlock();
  ```

  Casting away `const`, especially from something as precious as the genesis block, feels really weird to me as a reader of bitcoin-core source code.

  `m_assumed_blockchain_size` (src/chainparams.cpp:CChainParams) was

0890339 build: prefer python3.4 even if newer versions are present on the system (Sjors Provoost)

Pull request description:

  Python 3.4 is this mimimum supported version according to [doc/dependencies.md](https://github.com/bitcoin/bitcoin/blob/master/doc/dependencies.md)

  Systems with [PyEnv](https://github.com/pyenv/pyenv) ensure (via [.python-version](https://github.com/bitcoin/bitcoin/blob/master/.python-version)) that Python 3.4 is used
  for the functional tests. However `make check` calls `bitcoin-util-test.py`
  using the Python command found by `configure.ac`, which looks system wide.

  On systems with multiple versions of Python this would cause `make check`
  to fail, as it tries to call a version of Python that PyEnv blocks.

  This is solved by preferring python3.4 in `configure.ac`.

  This PR allows for key origin data as defined by the descriptors document to be imported to the wallet when importing a descriptor using `importmulti`. This allows the `walletprocesspsbt` to include the BIP 32 derivation paths for keys that it is watching that are from a different HD wallet.

  In order to make this easier to use, a new field `hdmasterkeyfingerprint` has been added to `getaddressinfo`. Additionally I have removed `hdmasterkeyid` as was planned. I think that this API change is fine since it was going to be removed in 0.18 anyways. `CKeyMetadata` has also been extended to store key origin info to facilitate this.

Pull request description:

  If the wallet has private keys disabled, allow importing public keys into the keypool. A `keypool` option has been added to `importmulti` in order to signal that the keys should be added to the keypool.

  Add missing `cs_main` locks required when accessing `pcoinsdbview`, `pcoinsTip` or `pblocktree`.

  This is a subset of bitcoin#15192: split up requested by MarcoFalke in bitcoin#15192 (comment).

  The end goal is to get the corresponding `GUARDED_BY(...)`:s in (see bitcoin#15192).

88a91e2 [build] AppVeyor: clean cache when build configuration changes (Sjors Provoost)

Pull request description:

  AppVeyor builds started starting failing on master after I cleaned the cache in bitcoin#15382. In addition, it appeared that a new dependency (boost-process) wasn't getting added in that PR without at least cleaning the vcpkg cache.

Adds a joinpsbts RPC which combines multiple distinct PSBTs into
one PSBT.

When signing an input, figure out what was requested for but was unable
to be found and store it in a SignatureData.

Return this information in SignPSBTInput.

08f749c Implement joinpsbts RPC and tests (Andrew Chow)
7344a7b Implement utxoupdatepsbt RPC and tests (Andrew Chow)

Pull request description:

  This PR adds 3 new utility RPCs for interacting with PSBTs.

  `utxoupdatepsbt` updates a PSBT with UTXO information from the node. It only works with witness UTXOs because full transactions (as would be needed for non-witness UTXOs) are not available unless txindex is enabled.

  `joinpsbts` joins the inputs from multiple distinct PSBTs into one PSBT. e.g. if PSBT 1 has inputs 1 and 2, and PSBT 2 has inputs 3 and 4, `joinpsbts` would create a new PSBT with inputs 1, 2, 3, and 4.

  `analyzepsbt` analyzes a PSBT and determines the current state of it and all of its inputs, and the next step that needs to be done.

fd637be Add checksums to descriptors.md (Pieter Wuille)
be62903 Make descriptor checksums mandatory in deriveaddresses and importmulti (Pieter Wuille)
b52cb63 Add getdescriptorinfo to compute checksum (Pieter Wuille)
3b40bff Descriptor checksum (Pieter Wuille)

Pull request description:

  This adds support for a descriptor-specific 8-character checksum.

  Descriptors may optionally be suffixed with a `#` plus these 8 checksum characters. Any descriptor that contains a `#` at the end must be followed by a valid checksum. If the `#` is missing entirely, it is valid without checksum.

  All RPCs are updated to report descriptors that include the checksum. On input, they are optional except in `deriveaddress` and `importmulti`, which require descriptors which include a checksum.

  A new RPC is also added to analyse descriptors (`getdescriptorinfo`), which can be used to compute the checksum for a descriptor without.
