Fix the git-* wrapper scripts, PRESUBMIT.py and .gitignore.

The previous python wrapping scripts assumed python_bin\python.exe. This CL
modifies the wrapping scripts to use python.bat. This requires some quoting
magic and explicitly defer to cmd.exe.

This may break some cases where double quotes are used as arguments. We can't do
miracles on Windows.

Newer versions of clang-format-diff.py now require a -i flag to

make "git cl format" a no-op.

This patch fixes the issue by probing the script's help text to

The motivation for this CL is:
When a project is turned on to use GitCheckout with try job verifiers, then the CQ crashes because of line 64 in http://src.chromium.org/viewvc/chrome/trunk/tools/commit-queue/pending_manager.py

This is because revision can only be one of (None, int, unicode). This crash only happens when try jobs are used (which is why I did not see it before).
This CL changes the return type to be unicode instead of string.

The callee needs it to be a string so that it can be made

it's useful to use non-string types for flags where
Rietveld actually doesn't return strings (say booleans).

This solves a problem with "os.rename" sometimes failing with an
exception after cloning a dependency to a temporary directory. It's
possible the dying git processes still hold a handle to the directory.
Since gclient delete the temporary directory regardless of the success
of the process, it results in a lot of GB downloaded for nothing.

SafeRename solves this by retrying a few times if the renaming fails,
sleeping one second every time to get other processes the time to
release their lock on the directory. It gives up retrying after 15 times.
