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.

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.

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
