cr: Ignore Ctrl-C while running shell programs

While running programs in an interactive subshell (cr shell), ignore
Ctrl-C in cr itself. This lets the child program handle Ctrl-C the best
way it sees fit without always terminating cr.

TEST=cr shell gdb # Press Ctrl-C => Neither gdb nor cr terminates.

Allow individual volume control of remote webrtc audio tracks.
This fixes an issue where remote audio tracks would all share the same volume state.  Although there's still a limitation in the audio stack, this brings us a step closer to spec compliance.

BUG=343998
TEST=I ran the currently disabled, yet functional WebRtc tests in content_unittests.  Also created my own test HTML page that renders the same media stream in multiple video tags and verified that individual volume control worked and that the volume could be boosted up to a max factor of 10.

Cache the boolean value in usingDelegatedRenderer.
As we are going to use this api at many places, caching the value at the first instance, will save the checking every time.

Move the translate script callbacks from TranslateManager to TranslateScript

This CL refactors the way callbacks for TranslateScript are handled.
Previously, only one callback was allowed, and thus TranslateManager was
managing a global list of pending script request to be able to merge all these
requests into one callback.

As we want to move away from TranslateManager being a singleton, the management
of TranslateScript requests is moved to TranslateScript (which is also cleaner).
TranslateScript now supports multiple callbacks.
