679365e7b9 Reduce gratuitous includes: don't include jail.h if it's not needed. 
Presumably, at some point, you had to include jail.h if you included
proc.h, but that is no longer required.

Result of:	self injury involving adding something to struct prison

75b8b3b25c Replace the at_fork, at_exec, and at_exit functions with the slightly more 
flexible process_fork, process_exec, and process_exit eventhandlers.  This
reduces code duplication and also means that I don't have to go duplicate
the eventhandler locking three more times for each of at_fork, at_exec, and
at_exit.

b254666064 Use td_ucred of curthread instead of p_ucred of curproc. This required 
changing sem_perm() and sem_hasopen() to take a thread instead of a proc
for the first argument.

efaa658806 Bring in my implementation of kernel support for posix realtime semaphores 
that are shareable between processes.

There will be a cleanup shortly along with the necessary changes made to
libc, libc_r, libpthread as well as the hooks into sys/conf and sys/modules.
