winverbs.sys: add initial support for CQ, SRQ, and QP

winverbs.sys: add initial support for CQ, SRQ, and QP

This adds the starting implementation for CQ, SRQ, and QP support.
Some code is restructured to relocate functions to different source
files.  This makes them easier to find and allows other functions to
become static.

The kernel driver now implements all synchronous verb related routines.
The code is compile tested only, and does not yet implement any
asynchronous routines (ones that involve the use of OVERLAPPED operations).
