The old code is effectively always posting iser_conn->min_posted_rx
descriptors, since it is
if (outstanding + iser_conn->min_posted_rx <= iser_conn->qp_max_recv_dtos) {
if(iser_conn->qp_max_recv_dtos - outstanding > iser_conn->min_posted_rx)
count = iser_conn->min_posted_rx;
else
count = iser_conn->qp_max_recv_dtos - outstanding;
which is equivalent to
if(iser_conn->qp_max_recv_dtos - outstanding >= iser_conn->min_posted_rx)
if(iser_conn->qp_max_recv_dtos - outstanding > iser_conn->min_posted_rx)
count = iser_conn->min_posted_rx;
else
count = iser_conn->min_posted_rx;
So the "if" is redundant and the "min_posted_rx" is actually behaving more
like a _maximum_ number of posted descriptors in one iser_post_recvm.
Fix it with the (presumably) intended logic and remove a goto along
the way.

The code was implicitly dependent on container_of from
inifiniband/verbs.h, however that's been removed in rdma-core
latest release:
ce0274acff
Define container_of locally if it's not already defined
Win32 has been rotting for a while. This patch adds vs17 build files
as well as fixing up all build errors that have accumulated.
There are still build warnings but those can be addressed in a followup
patch.

This splits a transport into static driver specific functions for the common
iscsi commands. Optionally, a driver specific opaque memory is introduced
which is currently only used by iSER transport.
Last a lot of functions changed to static.
