Some vendors want to add a field when a 'sruct sock' is added so give a hook to handle this. Any memory allocated when trace_android_rvh_sk_alloc() is called needs to be freed when trace_android_rvh_sk_free() is called. Note, if trace_android_rvh_sk_alloc() fails, be sure to be able to handle this in trace_android_rvh_sk_free(), but that should not be an issue as that needs to be addressed in vendor code that runs for 'struct sock' objects that have been created before the vendor code is loaded no matter what.
