mdoc: remove superfluous paragraph macros.

Add a resource limit for the total number of kqueues available to the
user. Kqueue now saves the ucred of the allocating thread, to
correctly decrement the counter on close.

Under some specific and not real-world use scenario for kqueue, it is
possible for the kqueues to consume memory proportional to the square
of the number of the filedescriptors available to the process. Limit
allows administrator to prevent the abuse.

This is kernel-mode side of the change, with the user-mode enabling
commit following.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Since setclasscpumask() is not static, assume that it is intended to be
part of the public API. Accordingly, add a prototype and document it.

- Import the HEAD csup code which is the basis for the cvsmode work.

Add support for a new login capability, cpumask which allows login
sessions to be pinned to cpus by login class.
