For the common, open coded 'skb->h.raw = skb->data' operation, so that we can
later turn skb->h.raw into a offset, reducing the size of struct sk_buff in
64bit land while possibly keeping it as a pointer on 32bit.
This one touches just the most simple cases:
skb->h.raw = skb->data;
skb->h.raw = {skb_push|[__]skb_pull}()
The next ones will handle the slightly more "complex" cases.

As of commit 6cdbd77e ("cxgb3 - missing CPL hanler and register
setting."), the cxgb3 ethernet NIC driver no longer handles SET_TCB
replies, so we need to do it in the iWARP driver.

Fix memory region permission problems:
- remove useless and redundant iwch_mem_perms enum.
- create ib_to_tpt_access_rights() for mapping ib access rights
to T3 TPT permissions.
- create ib_to_mwbind_access_rights() for mapping ib access rights
to T3 MWBIND WR permissions.
- fix up the mem reg code to utilize the new functions.

Fixes for "normal close" failures:
- Start normal close timer when moving to CLOSING state.
- Handle ABORTING state in close_con_rpl().
- Stop timer correctly on abort during a normal close.

If the consumer rejects the connection we end up under-referencing the
endpoint structure. The fix is to call iwch_ep_disconnect() instead
of the low level disconnect functions so that the endpoint close timer
is started correctly.

- don't mark static functions in C files as inline - gcc should know
best whether inlining makes sense
- never compile the unused cxio_dbg.c
- make the following needlessly global functions static:
- cxio_hal.c: cxio_hal_clear_qp_ctx()
- iwch_provider.c: iwch_get_qp()
- remove the following unused global functions:
- cxio_hal.c: cxio_allocate_stag()
