This add methods to compositor_util.cc to compute the number of
raster threads to be used in the renderer process. Then this number
is passed to the renderer process explicitly instead of just forwarding
a command line flag blindly.

If the renderer will use more than one thread, chrome://gpu will report
that "Multiple Raster Threads" is enabled, otherwise it shows disabled.
If the --num-raster-threads command line argument is used to force more
than one thread, then it will show Force enabled.

There is no change in behaviour with this patch, it still uses one thread
unless forced otherwise on the command line.

The problem is that some locales (Hindi) or platforms (Linux) have a
bigger base font size for the default font (crbug.com/405994). If this
is the case, we should decrease the font size to the one we expect,
so that the font fits in the button correctly.

Just adjusting the baseline is not always enough, as the new avatar
button has a fixed size, and the text might not fit correctly
regardless of the baseline adjustments.

Override the main() function from libppapi_stub, and rather than
simply failing when PPAPI is missing, assume that we are running
in sel_ldr and jump directly to the user's main function.

As a nice side effect this removes the needs to SEL_LDR=1 builds.

This component handles the protocol between Chrome and an associated phone for
the Easy Unlock and Easy Sign-in features.

The system is currently implemented as a Chrome packaged app, and this is the
first step in migrating this functionality to native code. We will gradually
reimplement the system and switch from the app to this component once the
refactoring is complete.
