Handle KeyboardInterrupt gracefully rather the printing a
backtrace. Most users of these tools don't expect a
backtrace when then hit Ctrl-C.
Also, fix a few other inconsistencies found in the python
startup code of these different scripts:
- always call main function 'main' (rather than 'Main')
- always return 0 from main function
- if main takes args never include argv[0]

Updated 'git-number' to produce an error message if it's run without the
CHROME_HEADLESS (bot) environment variable. This is intended to alert developers
who may be incorrectly using this tool to get positioning information instead of
the commit position.
BUG=409917
TEST=local
- Ran with and without 'CHROME_HEADLESS'; observed the error message in the
'without' case.

git-map: Show your local repo's history in a pseudo-graphical format from the command line.
git-map-branches: Show the topology of all of your branches, and their upstream relationships.
git-nav-upstream: Navigate (checkout) to the upstream branch of the current branch.
git-nav-downstream: Navigate (checkout) to a downstream branch of the current branch. If there's more than one downstream branch, then present a menu to select which one you want.

Compatible with any git topology (multiple roots, weird branching/merging, etc.)
I can't get it to be any faster (in python). Suggestions welcome :).
On z600/linux, this takes 5.1s to calculate the initial count for 2e3de954ef0a
(HEAD on src.git at the time of writing). Subsequent lookups take ~0.06s. For
reference, this machine takes 3s to just list the revisions in sorted order
without any additional processing (using rev-list).
All calculations are stored in a git-notes-style ref with the exception that the
leaf 'tree' object which would normally be stored in a git-notes world is
replaced with a packed binary file which consists of records [hash int]. Each
run of this script will create only 1 commit object on this internal ref which
will have as its parents:
* The previous git number commit
* All of the target commits we calculated numbers for.
This ref is then excluded on subsequent invocations of rev-list, which means that
git-number will only ever process commit objects which it hasn't already
calculated a value for. It also prevents you from attempting to number this
special ref :).
This implementation only has a 1-byte fanout which seems to be the best
performance for the repos we're dealing with (i.e. on the order of 500k commit
objects). Bumping this up to a 2-byte fanout became extremely slow (I suspect
the internal caching structures I'm using are not efficient in this mode and
could be improved). Using no fanout is slower than the 1 byte fanout for lookups
by about 30%.
