[Chromium] Pipe getFontDataForCharacters via ChromiumBridge

[Adam Langley]

This is hopefully the last step before our renderers can run cleanly in a chroot.

WebKit needs to be able to ask for the correct font to use in the case that the current font doesn't include glyphs for certain code points. Currently we make a fontconfig call in our WebKit port to handle this.

This patch changes this so that the call is sent our via ChromiumBridge.

I'm leaving the "real" review for Darin Fisher, but I'll give you some style things to fix up to make it go faster.

Typically the link to the bug is near the top of the change log entry.  (I did see you put it in bug it way at the bottom.)

"characters" doesn't seem to add any information here due to the api name and the const UChar* type.
So it would be good to remove it.  (WebKit style is to not put in param names when they don't add information.)

Use 0 instead of NULL.

My only comment, in addition to what Dave wrote, is that numCharacters should probably be size_t instead of int.  Post a revised patch and LGTM.

Opps, sorry.
