Split IPC logging between content and chrome.
I add a new content API to register IPC message loggers, and modify the IPC
message macros to not directly create the g_log_function_mapping. That allows
for multiple files generating IPC loggers. Also, it gets rid of the ctor/dtor
for the g_log_function_mapping.
