[PATCH 1/7] libibumad: Provide MAD definitions with libibumad

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

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

The only definitions for MAD data types are in ib_types.h, which
is an opensm file.  The libibumad interface is essentially useless
without these data types.  Add new header files to libibumad
with basic MAD data types.

The definitions and structures are based on those defined in
the linux kernel.  Only an initial framework is given, basically
the values for various methods, attributes, etc. along with
structure definitions for the common, rmpp, and vendor specific
headers.  Other data structures are left for future development.
