Better command line arg parsing for play_testcase.py

Makes the play_testcase.py script more configurable. The current behaviour
of running whatever it finds is unpredictable. The command line arguments
syntax has changed, so callers will need to adapt.

[Download] Return DownloadInterruptReason from OnStartedCallback

DownloadUrlParameters::OnStartedCallback is invoked when the server
response is received for a newly started download. If there's an error,
this callback used to receive a net::Error indicating why.

This CL changes the return value to a DownloadInterruptReason so that
the callback can indicate error conditions that affect downloads that
aren't considered errors at the network layer. Also, it avoids having to
call DownloadManager::Start() when the response indicates that a
download is not possible.

Currently downloads that fail to start return a net::Error, but those
that fail after starting return a DownloadInterruptReason. With this
change, all downloads will return a DownloadInterruptReason regardless
of when the download is interrupted.

Remove NVIDIA entry from blacklist

It turns out that it's not this particular driver which caused the pink
screen but rather a 3D vision setting.

Don't use SVN revision for Chromoting Android APK internal version.

An APK built from a later Chromium branch should have a higher version
number than one built from an earlier branch. This CL fixes the
Chromoting Android package's internal version to have that property.

The scheme implemented here matches official Chrome.apk.
