Add definitions for path record wire definition. This
will be used by the librdmacm and ib_acm service, and is
exchanged with the kernel using the newer set and query

I went with the simpler definition, rather than defining bitfields.
Once a definition is accepted into the libibverbs git tree, I will
request that the same definition be pulled into the OFED 1.5.2 codebase.
