[PATCH 3/8] build: Add build support for XRC

[sean.hefty-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org]

From: Sean Hefty <sean.hefty-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

Modify autotools to check for and require a libibverbs
version that includes XRC and extension support.

Remove any code used to support older versions of
libibverbs.
