Update the OFED Infiniband core to the version supplied in Linux
version 3.7.
The update to OFED is nearly all additional defines and functions
with the exception of the addition of additional parameters to
ib_register_device() and the reg_user_mr callback.
In addition the ibcore (Infiniband core) and ipoib (IP over Infiniband)
have both been made into completely loadable modules to facilitate
testing of the OFED stack in FreeBSD.
Finally the Mellanox Infiniband drivers are now updated to the
latest version shipping with Linux 3.7.

newvers.sh. Pass it in from include/Makefile. If it isn't passed in,
fall back to the old logic of using dirname $0.
Using dirname $0 does not yield the path to the script if it was
sourced in from another script in another directory; you end up with
the parent script's path. That was causing newvers.sh to look one
level below the FreeBSD src/ directory when building osreldate.h and it
may find something like a git or svn repo there that has nothing to do
with FreeBSD.

Without these, if the timeout value passed is "large enough", the
value of the sum of it and other factors (e.g. current time as
returned by sbinuptime() or 'precision' argument) might result in a
negative number. This negative number is then passed to
eventtimers(4), which causes et_start() routine to load et_min_period
into eventtimer, making the CPU where the thread is stuck forever in
timer interrupt handler routine. This is now avoided rounding to
INT64_MAX the timeout period in case of overflow.
