Merge branch 'git-svn'

Include `git svn` support. It does increase the size of the executable
from 31MB to 40MB, but we cannot simply stop supporting `git svn`.

Besides, we need to reward the hard work of the contributor @nalla who
worked on MSys2-based Git for Windows to be able to use newer Subversion
features in `git svn`.
