Tested with:
* Unit tests have been added and they work.
* I also tested end-to-end using a skiabot-test repository in https://skia.googlesource.com/ (it is hidden). CLs I tested with are:
** https://codereview.chromium.org/22797006/ : Add whitespace in file1
** https://codereview.chromium.org/22815013/ : Remove whitespace from file1
** https://codereview.chromium.org/22867025/ : Add new files in directories
** https://codereview.chromium.org/22901018/ : Edit file in directory and delete file in directory
** https://codereview.chromium.org/22918014/ : Add, Delete and Modify 3 files
** https://codereview.chromium.org/23360004/ : Add new files in new directories


Note:
* When committing GitCheckout uses the --author to specify the original author. The author flag takes in 'Firstname Lastname <email_addr>' but we do not know the Firstname and LastName of the original author, which is why the code here parses out the username from the email address and uses it.
  Eg: For email address xyz@example.com it passes in --author 'xyz <xyz@example.com>'
* An example of the changes required in a project to use GitCheckout instead of SvnCheckout is in https://codereview.chromium.org/22859063/

Use the code in git_cl.py, since it was the more evolved. Add documentation
and clean up the structure along the way.

This makes it possible to easily reuse the generic subcommand handling code.

As a first step, only git_cl.py is using it. Eventually, gclient and gcl could
be switch over.

Currently the output is:

This format is extremely annoying because you must combine the
file and line number together by hand. A more standard format
for expressing a position in a file is filename:lineno. This
changes the format to match:
