winverbs: fix memory violation in SRQ code
Problem reported by Shiqing Fan:
"I got a memory violation error in wv_srq.cpp Query() function around
line 202. It seems using uninitialized verbsData.output_size for
memcpy. The verbsData.input_size is initialized in WvPreQueryQp
(wvuverbs.cpp), and it has a similar memcpy in this function too."
wv_uverbs.cpp should initialize the output_size to 0 in all
WvPre* calls.

winverbs: add mr interface
The lkey isn't guaranteed to be unique. To ensure that we track
memory registrations properly, associate MRs with their own data
structure. Deregistration will reference the data structure, rather
than just the lkey from the registration.

libibverbs: remove _errno include from verbs.h
verbs.h is intended to be included directly by applications. Since
_errno.h is a linux header file abstraction, move its use internal
to libibverbs. This avoids issues if the user includes errno.h
directly.

libibverbs: remove duplicate wc status values
Several ibv_wc_status values map to the same winverbs wc status
values. This causes an error if the ibv_wc_status values are
referenced in a switch statement. Replace the duplicated values
with constants, so every wc status value is unique.
Since the wc status values are mapped from the provider library,
the duplicated values are not used anyway.
