Do extensions update manifest XML parsing in a sandboxed process.

This involves moving the xml parsing code from static functions in 
extension_updater.cc to a UpdateManifest class, and switching from 
logging any errors directly to collecting them up and passing them 
across the IPC channel.

TEST=extensions auto-update should still work correctly
