Fix a bug in ld, where indirect symbols are not handled properly during
linking of a shared library, leading to corrupt indexes in the dynamic
symbol table.  This should fix the multimedia/ffmpegthumbnailer port.

Update OFED to Linux 3.7 and update Mellanox drivers.

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.

Fix ixp425 boot2 with ARM EABI:
 - libkern is missing __aeabi_llsl, implement this by calling __ashldi3.
 - Because of how the asm entry macros are defined the boot2 code
   requires the unwind symbols to exist, include them in boot2.

Add LK_TRYUPGRADE operation for lockmgr(9), which attempts to

Reimplement r255797 using LK_TRYUPGRADE.

The  r255797 was:
Increase the chance of the buffer write from the bufdaemon helper
context to succeed.  If the locked vnode which owns the buffer to be
written is shared locked, try the non-blocking upgrade of the lock to
exclusive.

For vunref(), try to upgrade the vnode lock if the function was called
with the vnode shared-locked.  If upgrade succeeded, the inactivation
can be done immediately, instead of being postponed.

Changes to CAM or busdma have caused SIMs to be sent 0-length CCBs on
occasion. This resulted in zero mapped segments, triggering an assert in
the PS3 CDROM driver. Allow no DMA for 0-length transfers.

Use MK_SSP=no after including bsd.own.mk to disable SSP instead of user-knob
WITH[OUT]_SSP to avoid hitting an error if user has WITH_SSP in their
make.conf. Ports now use this knob.

  make[7]: "/usr/src/share/mk/bsd.own.mk" line 466: WITH_SSP and
  WITHOUT_SSP can't both be set.

This is similar to previous cleanup done in r188895
