Removed dependency on MissingH, instead depending on the split
library.
After laying groundwork for this since 2015, it
was mostly straightforward. Added Utility.Tuple and
Utility.Split. Eyeballed System.Path.WildMatch while implementing
the same thing.
Since MissingH's progress meter display was being used, I re-implemented
my own. Bonus: Now progress is displayed for transfers of files of
unknown size.

Cryptonite is faster and allocates less, and I want to get rid of
MissingH use.
Note that the new dependency on memory is free; it's a dependency of
cryptonite.

Moving toward dropping MissingH dep.
I think I've addressed the problem identified earlier in
09a66f702d. On Windows,
absPathFrom "/tmp/repo/xxx" "y/bar" would be "/tmp/repo/xxx\\y/bar",
which then confuses relPathDirToFile. Fixed by converting to unix (git)
style paths.
Also, relPathDirToFile was splitting only on \\ on windows and not /
which broke the example in 09a66f702d of
relPathDirToFile (absPathFrom "/tmp/repo/xxx" "y/bar") "/tmp/repo/.git/annex/objects/xxx"
Now, on windows, that will yield "..\\..\\..\\.git/annex/objects/xxx"
which once converted to unix style paths is what we want.
When ssh connection caching is enabled (and when GIT_ANNEX_USE_GIT_SSH is
not set), only one ssh password prompt will be made per host, and only one
ssh password prompt will be made at a time.
This also fixes a race in prepSocket's stale ssh connection stopping
when run with -J. It was possible for one thread to start a cached ssh
connection, and another thread to immediately stop it, resulting in excess
connections being made.
