[infiniband] Return status code from ib_create_cq() and ib_create_qp()
Any underlying errors arising during ib_create_cq() or ib_create_qp()
are lost since the functions simply return NULL on error. This makes
debugging harder, since a debug-enabled build is required to discover
the root cause of the error.
Fix by returning a status code from these functions, thereby allowing
any underlying errors to be propagated.

[retry] Hold reference while timer is running and during expiry callback
Guarantee that a retry timer cannot go out of scope while the timer is
running, and provide a guarantee to the expiry callback that the timer
will remain in scope during the entire callback (similar to the
guarantee provided to interface methods).

Access to the gpxe.org and etherboot.org domains and associated
resources has been revoked by the registrant of the domain. Work
around this problem by renaming project from gPXE to iPXE, and
updating URLs to match.
Also update README, LOG and COPYRIGHTS to remove obsolete information.

[infiniband] Generate more specific errors in response to failure MADs
Generate errors within individual MAD transaction consumers such as
ib_pathrec.c and ib_mcast.c, rather than within ib_mi.c. This allows
for more meaningful error messages to eventually be displayed to the
user.
[infiniband] Add the concept of a management interface
A management interface is the component through which both local and
remote management agents are accessed.
This new implementation of a management interface allows for the user
to react to timed-out transactions, and also allows for cancellation
of in-progress transactions.
