Update oilpan plugin, now includes plugin code as of r255054.

As described on https://code.google.com/p/chromium/wiki/UpdatingClang ,
lower part.

We replaced the existing clang-198389.tgz package on googlestorage
with a new one that's identical to the old one (same compiler binary) except
that there's now a libBlinkPlugin_2.so in the package too. That so isn't used
yet, so this shouldn't have a behavior change (except that it'll cause runhooks
to update everyone's clang packages to the one including the plugin.)

Move ExtensionFunctionRegistry out of src/chrome

This is mostly a mechanical change with the exception that
ExtensionsBrowserClient has a new method for registering
additional extensions functions with the registry.

Chrome-dependent function registration has been moved to
the ChromeExtensionsBrowserClient implementation.
