ChromeOS mixer: Talk to new ChromeOS audio server.

ChromeOS mixer: Talk to new ChromeOS audio server.

Instead of talking to ALSA in dB we talk to the new audio
server (CRAS) in percent. CRAS will contain a board-specific
volume curve for mapping percent to dB.

LGTM, built and ran from the chroot with use_cras defined.

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer or
a lowly provisional committer, _not_ a full super star committer.
See http://www.chromium.org/getting-involved/become-a-committer
Note that this has nothing to do with OWNERS files.

(Not sure if it'll work, but self-LGTM-ing.  This is Dylan's change and I
