No need to support UL_GETSIZE and UL_SETSIZE anymore; they are about to be
renamed in RELENG_5_0.

Rename UL_GETSIZE to UL_GETFSIZE and UL_SETSIZE to UL_SETFSIZE; these are
the names required by 1003.1-2001. The old names are retained for
source compatibility with FreeBSD 5.0 and will be removed before 6.0.

Bracket the prototype for ulimit() with __BEGIN_DECLS/__END_DECLS
so that it can be called from C++.

Implement POSIX.1-2001 (XSI)'s ulimit(3).
