hg2git.py: Refactor main code into hg2git() function

simply calling the hg2git() function.

Except some config values nobody really ever wants to change, it's even
save to run several hg2git() functions in parallel as no global vars or
the like are used by intention (but it makes the code uglier).

hg2git.sh: Try to get last hg repo url from state file

As one usually mirrors a git repo based on the same hg repo, it's
annoying having to specify the hg repo url all the time. Since we

Speedup: Use manifest and compare checksums to detect changes

Instead of feeding in everything or only something and getting merges
wrong, build up a list of changed (incl. added) and deleted files by

  1) comparing manifest (deleted, added)
  2) comparing checksums if file is present in parent and child (change)

The hg-crew and mutt imports now go in <15 minutes and md5 sums match.

Thanks to Theodore Tso for the hint.

While at it, fix a regression that upon incremental import start we
always merged a branch plus initializing it. A single test showed that
the new detection get starting off from a merge commit right, too.
