zstandard: vendor python-zstandard 0.13.0
Version 0.13.0 of the package was just released. It contains
an upgraded zstd C library which can result in some performance
wins, official support for Python 3.8, and a blackened code base.
There were no meaningful code or functionality changes in this
release of python-zstandard: just reformatting and an upgraded
zstd library version. So the diff seems much larger than what it
is.
Files were added without modifications.
The clang-format-ignorelist file was updated to reflect a new
header file in the zstd distribution.

Create extension that can disable exec checks:
$ cat > noexec.py <<EOF
> from mercurial import extensions, util
> def setflags(orig, f, l, x):
> pass
> def checkexec(orig, path):
> return False
> def extsetup(ui):
> extensions.wrapfunction(util, 'setflags', setflags)
> extensions.wrapfunction(util, 'checkexec', checkexec)
> EOF
