[PATCH] RLIM: add rlimit entry for controlling queued signals 

The following patches introduce per user rlimits for both queued signals and
POSIX message queues.  The changes touch all the arches resource.h files as
well as init_task.c to get the rlimit defaults setup.

Both require caching the user_struct to avoid problems with setuid().

The signal changes makes some small changes to send_signal() to pass along the
task being signalled to get proper accounting for signals initiated in
interrupt.  Thanks to Marcelo for getting this one going.


This patch:

Add an rlimit entry to control the maximum number of pending signals a user
may have.  This is essentially just the resource.h changes.
