Add unit test calling CreateWalletFromFile, which isn't currently called from
other unit tests, with some basic checks to make sure it rescans and registers
for notifications correctly.
Motivation for this change was to try to write a test that would fail without
the early `handleNotifications` call in ef8c6ca60767cac589d98ca57ee33179608ccda8
from https://github.com/bitcoin/bitcoin/pull/16426, but succeed with it:
ef8c6ca607/src/wallet/wallet.cpp (L3978-L3986)
However, writing a full test for the race condition that call prevents isn't
possible without the locking changes from #16426. So this PR just adds as much
test coverage as is possible now.
This new test is also useful for https://github.com/bitcoin/bitcoin/pull/15719,
since it detects the stale notifications.transactionAddedToMempool notifications
that PR eliminates.
A bad interaction between valgrind and clang 6.0.0-1ubuntu2 with -O2
optimizations makes valgrind misleadingly imply C++ code is reading an
uninitialized blockheight value in rest_blockhash_by_height just because that's
what clang optimized code is doing. The C++ code looks like:
int32_t blockheight;
if (!ParseInt32(height_str, &blockheight) || blockheight < 0) {
while the optimized code looks like:
0x00000000000f97ab <+123>: callq 0x4f8860 <ParseInt32(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int*)>
0x00000000000f97b0 <+128>: mov 0xc(%rsp),%ebx
0x00000000000f97b4 <+132>: test %ebx,%ebx
0x00000000000f97b6 <+134>: js 0xf98aa <rest_blockhash_by_height(util::Ref const&, HTTPRequest*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)+378>
0x00000000000f97bc <+140>: xor $0x1,%al
0x00000000000f97be <+142>: jne 0xf98aa <rest_blockhash_by_height(util::Ref const&, HTTPRequest*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)+378>
During the rest_interface.py test:
self.test_rest_request("/blockhashbyheight/", ret_type=RetType.OBJ, status=400)
when height_str is empty, ParseInt32 returns false and blockheight value is
never assigned. The optimized code reads the uninitialized blockheight value
in 0xc(%rsp) before the checking the ParseInt32 return value in %al, which is
harmless, but triggers the following error from valgrind:

This is a known bad interaction between clang and valgrind. The clang optimized
code is correct but valgrind has no way of knowing that accessing the
uninitialized value isn't a problem. Issue has been reported previously:
https://bugs.llvm.org/show_bug.cgi?id=32604#c4https://github.com/Z3Prover/z3/issues/972
This commit just sets blockheight to 0 as a workaround.

2495110012 test: add coverage for -rpcwallet cli option (Jon Atack)
Pull request description:
The bitcoin-cli `-rpcwallet=` option is an essential RPC/CLI option when more than one wallet is loaded (see `bitcoin-cli -help | grep -A5 rpcwallet` or `src/bitcoin-cli.cpp::L61`) and it currently has no test coverage.
It is not only used by users, but also by the test framework and ~10 test files via `get_wallet_rpc()`.
This PR adds coverage, while simultaneously improving the `-getinfo` coverage when multiple wallets are loaded. This is similar to the test coverage that would be added in #18594.

eb37275a6f Fix naming of macOS SDK and clarify version (Andrew Chow)
Pull request description:
Fixes the `MacOSX10.14.sdk.tar.gz` creation command to have `MacOSX.sdk` be correctly named as `MacOSX10.14.sdk` and for the resulting file to be placed in the current directory. Gitian requires that `tar.gz` contains a folder named `MacOSX10.14.sdk` and the command did not do this originally. Having the file be placed in the current directory is a convenience so builders don't have to go find it.
Also clarifies which version of Xcode to download and where it can be downloaded.

Check that...
- mempool tracks & reattempts delivery of a transaction where a GETDATA hasn't
been requested by a peer yet.
- transaction delivery is not attempted again after GETDATA is received.
- transaction is removed from the unbroadcast set when its removed from the
mempool.
Since the mempool unbroadcast mechanism handles the reattempts for initial
broadcast, the wallet rebroadcast attempts can be much less frequent
(previously ~1/30 min)
- Mempool tracks locally submitted transactions (wallet or rpc)
- Transactions are removed from set when the node receives a GETDATA request
from a peer, or if the transaction is removed from the mempool.
Adds a --descriptors option globally to the test framework. This will
make the test create and use descriptor wallets. However some tests may
not work with this.
Some tests are modified to work with --descriptors and run with that
option in test_runer:
* wallet_basic.py
* wallet_encryption.py
* wallet_keypool.py
* wallet_keypool_topup.py
* wallet_labels.py
* wallet_avoidreuse.py
