When extra entropy is not specified by the caller, CKey::Sign will
now always create a signature that has a low R value and is at most
70 bytes. The resulting signature on the stack will be 71 bytes when
the sighash byte is included.
Using low R signatures means that the resulting DER encoded signature
will never need to have additional padding to account for high R
values.
Just calling atoi to convert strings to integers does not check for
valid integers very thoroughly; in particular, it just ignores
everything starting from the first non-numeral character. Even a string
like "foo" is fine and silently returns 0.
This meant that bitcoin-tx would not fail if such a string was passed in
various places where an integer is expected (like the locktime or an
input/output index); this means that it would, for instance, silently
accept a typo and interpret it in an unexpected way.
In this change, we use ParseInt64 for parsing strings to integers,
which actually verifies that the full string is valid as number.
New tests in the bitcoin-util-test cover the new error paths.
* Pass `sys.executable` when calling a python script via the subprocess
module
* Don't remove the log file while it is still open and written to
* Properly use os.pathsep and os.path.sep when modifying the PATH
environment variable
* util-tests: Use os.path.join for Windows compatibility

Pull request description:
The subtree-merge commit also fixes the whitespace for failing tests, such that bisect doesn't break.
Finally, the bump also includes the changes that accidentally modified our subtree, such that the subtree check should work fine now:

fafff1220 qa: Restore bitcoin-util-test py2 compatibility (MarcoFalke)
Pull request description:
Currently `./configure && make check` will look for python3, then python2. As long as we support python2 (and use it as fallback), `make check` should run fine with both python2 and python3.

Pull request description:
Builds on top of #11117.
This adds support for:
* Creating BIP173 addresses for testing (through `addwitnessaddress`, though by default it still produces P2SH versions)
* Sending to BIP173 addresses (including non-v0 ones)
* Analysing BIP173 addresses (through `validateaddress`)
It includes a reformatted version of the [C++ Bech32 reference code](https://github.com/sipa/bech32/tree/master/ref/c%2B%2B) and an independent implementation of the address encoding/decoding logic (integrated with CTxDestination). All BIP173 test vectors are included.
Not included (and intended for other PRs):
* Full wallet support for SegWit (which would include automatically adding witness scripts to the wallet during automatic keypool topup, SegWit change outputs, ...) [see #11403]
* Splitting base58.cpp and tests/base58_tests.cpp up into base58-specific code, and "address encoding"-code [see #11372]
* Error locating in UI for BIP173 addresses.

bctest.py is only used as an import by bitcoin-util-test.py. There's no
value in keeping it as a separate module, so let's merge them into a
single module to keep building and packaging simpler.
bitcoin-test-util is importable as a module, so if any future modules
really want to import the code from bctest.py, they can import
bitcoin-test-util and call the bctest functions by name.
The functional tests and util tests both require a config file that is
generated by ./configure. This commit merges those two config
files into a single configuration file that can be shared by both tests.
The config from config.ini is put into a Namespace object to maintain
the interface with bctest.py. A future commit could change this
interface to use a dictionary instead of a namespace.
