Renewal of OAuth2 credentials did not work on appengine because it
replies with 302 instead of 401 when authentication fails. Configured
it to attempt credentials renewal on a 302.

Of course this will prevent any 302 from working normally, but it works
with Rietveld since it does not use 302.

Sometimes, removing lockfiles fails on windows, for obscure reasons.
Following advice from gclient_utils.rmtree, lock file removal has
been improved by using the builtin executable 'del' and retrying 3
times in case it fails.

This is a stopgap to prevent people with >20 local branches from running tools
like 'git rebase-update'. This usually indicates that the user isn't in the
habit of cleaning up old branches, which makes these tools unlikely to be useful
in the current state of their repo anyway.

When rietveld.py overrides upload.py's logging module, it generally works fine...
until someone tries to run upload.py with any level of verbosity. Then the
calls to logging.getLogger and logging.INFO/logging.DEBUG fail. This patches
upload.py to properly use a module-scope logger so that rietveld.py doesn't
have to perform invasive surgery, and everything just works.

This version of upload.py taken from upstream Rietveld at:

Evidence indicates that running non-builtin git commands is very
slow in msysgit, slow enough to dominate the running time of
gclient sync.  With this change, gclient never shells out to
git-cache; it import the lib directly instead.

Features:

- Non-verbose output is now limited to a one-line progress
indicator.

- Verbose output is now collated per subprocess.  As soon as a
subprocess finishes, its full output is dumped to terminal.

- Verbose output is prefixed with timestamps representing elapsed
time since the beginning of the gclient invocation.

- git progress indicators ("Receiving objects", etc.) are limited to
one line every 10 seconds.

- In both verbose and non-verbose mode, if a failure occurs, the
full output of the failed update operation is dumped to terminal
just before exit.

- In the event that updates are progressing, but slowly,
"Still working" messages will be printed periodically, to pacify
users and buildbots.
