Siddharth Agarwal e7b4906871 git_handler: mark source for rename info as Git or Mercurial
See inline comments for why the additional metadata needs to be stored.

This literally breaks all the hashes because of the additional metadata. The
changing of hashes is unfortunate but necessary to preserve bidirectionality.

While this could be broken up into multiple commits, there was no way to do
that while preserving bidirectionality. Following the principle that every
intermediate commit must result in a correct state, I decided to combine the
commits.

1. Ensure gitlinks are transformed to .hgsubstate on hg <- git pull
.hgsub shall list two [git] subrepos
$ cat .hgsub | sort
subrepo1 = [git]../gitsubrepo
xyz/subrepo2 = [git]../gitsubrepo
.hgsubstate shall list two idenitcal revisions
$ cat .hgsubstate
56f0304c5250308f14cfbafdc27bd12d40154d17 subrepo1
56f0304c5250308f14cfbafdc27bd12d40154d17 xyz/subrepo2
hg status shall NOT report .hgsub and .hgsubstate as untracked - either ignored or unmodified
$ hg status --unknown .hgsub .hgsubstate
$ hg status --modified .hgsub .hgsubstate
$ cd ..
2. Check gitmodules are preserved during hg -> git push
$ cd gitsubrepo
$ echo gamma > gamma
$ git add gamma
$ fn_git_commit -m 'add gamma'
$ cd ..
$ cd hgrepo
$ cd xyz/subrepo2
$ git pull | sed 's/files/file/;s/insertions/insertion/;s/, 0 deletions.*//' | sed 's/| */| /'

bring working copy to HEAD state (it's not bare repo)
$ git reset --hard
HEAD is now at ae335e3 Update subrepo2 from hg
$ cd ..
3. Check .hgsub and .hgsubstate from git repository are merged, not overwritten
$ hg init hgsub
$ cd hgsub
$ echo delta > delta
$ hg add delta
$ fn_hg_commit -m "add delta"
$ echo "`hg tip --template '{node}'` hgsub" > ../gitrepo1/.hgsubstate
$ echo "hgsub = $(pwd)" > ../gitrepo1/.hgsub
$ cd ../gitrepo1
$ git add .hgsubstate .hgsub
$ fn_git_commit -m "Test3. Prepare .hgsub and .hgsubstate sources"
$ cd ../hgrepo
$ hg pull
pulling from $TESTTMP/gitrepo1
importing git objects into hg
(run 'hg update' to get a working copy)
We grep off the updating to active bookmark message from newer versions. When
only 2.7 or later (or so) is supported, this grep should be dropped.
$ hg checkout -C | grep -v 'updating to active bookmark master' | egrep -v '^\(activating bookmark master\)$'
cloning subrepo hgsub from $TESTTMP/hgsub
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ cd ..
pull shall bring .hgsub entry which was added to the git repo
$ cat hgrepo/.hgsub | sort
hgsub = $TESTTMP/hgsub
subrepo1 = [git]../gitsubrepo
xyz/subrepo2 = [git]../gitsubrepo
.hgsubstate shall list revision of the subrepo added through git repo
$ cat hgrepo/.hgsubstate
