Care to first just consolidate the code from the binary handlers to
exec.c and then restrucure it? Currently mainline doesn't even
have ptrace_event yet so it's hard to verify the code is the same.
It certainly isn't for binfmt_som although that's like just a bugfix
that needs to be documented. Also the two new routines are too large
to be inlined, and I would rather not rely on the guarantee that no
other caller will pop up.
