rust-filepatterns: export glob_to_re function

Making this function public should not risk freezing the internal API,
and it can be useful for all downstream code that needs to perform
glob matching against byte strings, such as RHGitaly where it will
be useful to match on branches and tags.

# By default we build a .deb where the native components are built with the
# current "default" version of py3 on the build machine. If you wish to build a
# .deb that has native components built for multiple versions of py3:
#
#   1. install python3.x and python3.x-dev for each version you want
#   2. set DEB_HG_MULTI_VERSION=1 or DEB_HG_PYTHON_VERSIONS in your environment
#      (if both are set, DEB_HG_PYTHON_VERSIONS has precedence)
#
# If you choose `DEB_HG_MULTI_VERSION=1`, it will build for every "supported"
# version of py3 that's installed on the build machine. This may not be equal to
# the actual versions that are installed, see the comment above where we set
# DEB_HG_PYTHON_VERSIONS below. If you choose to set `DEB_HG_PYTHON_VERSIONS`
# yourself, set it to a space-separated string of python version numbers, like:
#   DEB_HG_PYTHON_VERSIONS="3.7 3.8" make deb
DEB_HG_MULTI_VERSION?=0

# Set to 1 to make /usr/bin/hg a symlink to chg, and move hg to
# /usr/lib/mercurial/hg.

	# package, and this file is not dynamic and does not account for manual
	# installations, just the ones that would be installed by `python3-all`. This
	# includes the `-i` flag, which claims it's to list all "installed" versions,
	# but it doesn't. This was quite confusing, hence this tale of woe. :)
