Workaround deps2git issue with inline Python in DEPS.

When running
https://code.google.com/p/chromium/codesearch#chromium/tools/deps2git/deps2git.py
on our DEPS file, an error is caused by the formatting pretty printing
of the converted DEPS -> .DEPS.git output.
Since this needs to work in order to switch our bots to bot_update
(uses Git) and the fact that changing deps2git.py is high risk, it's
better to work around this problem by altering the Python inline code.
The fact that deps2git will go away when the remaining projects
have switched to Git also motivates not taking the risk of changing
deps2git for this case only.

BUG=3534
TESTED=Ran gclient runhooks and verified the script executed
when there was a trunk/check_root_dir.py file.

Reland 28629004: adding new AEC dump start interface for chrome.

This is required because we are not allow to pass CRT objects across dll boundaries, that says, when we pass a file descriptor from chrome dll to libpeerconnection dll, the file descriptor will become invalid immediate, more information can be found here:

Remove talk_base from suppressions.

This namespace doesn't exist anymore, so remove all suppressions that
include it in the call stack.

Mark all virtual overrides in the hierarchy of Transport as virtual + OVERRIDE. 
This also marks all virtual overrides of other classes in the same files. 

This will make a subsequent change I intend to do safer, where I'll change the 
argument types of the base Transport functions, by breaking the compile if I 
miss any overrides. 

This also highlighted a number of unused functions. I've removed some of these.
