Remove configure probe and related tests for getrlimit.

Browse Source 
getrlimit() is in SUSv2 and all targeted systems have it.

Windows doesn't have it.  We could just use #ifndef WIN32, but for a
little more explanation about why we're making things conditional, let's
retain the HAVE_GETRLIMIT macro.  It's defined in port.h for Unix systems.

On systems that have it, it's not necessary to test for RLIMIT_CORE,
RLIMIT_STACK or RLIMIT_NOFILE macros, since SUSv2 requires those and all
targeted systems have them.  Also remove references to a pre-historic
alternative spelling of RLIMIT_NOFILE, and coding that seemed to believe
that Cygwin didn't have it.
