Contains:
* Refactor the hardware RNG CPU instruction sources to feed into
the software mixer. This is unfinished. The actual harvesting needs
to be sorted out. Modified by me (see below).
* Remove 'frac' parameter from random_harvest(). This was never
used and adds extra code for no good reason.
* Remove device write entropy harvesting. This provided a weak
attack vector, was not very good at bootstrapping the device. To
follow will be a replacement explicit reseed knob.

Remove invalid assert in DAGTypeLegalizer::RemapValue
There is a comment at the top of DAGTypeLegalizer::PerformExpensiveChecks

// Note that these invariants may not hold momentarily when processing a node:
// the node being processed may be put in a map before being marked Processed.
Unfortunately, this assert would be valid only if the above-mentioned invariant
held unconditionally. This was causing llc to assert when, in fact,
everything was fine.

When helping the bufdaemon from the buffer allocation context, there
is no sense to walk the whole dirty buffer queue. We are only
interested in, and can operate on, the buffers owned by the current
vnode [1]. Instead of calling generic queue flush routine, do
VOP_FSYNC() if possible.
Holding the dirty buffer queue lock in the bufdaemon, without dropping
it, can cause starvation of buffer writes from other threads. This is
esp. easy to reproduce on the big memory machines, where large files
are written, causing almost all dirty buffers accumulating in several
big files, which vnodes are locked by writers. Bufdaemon cannot flush
any buffer, but is iterating over the whole dirty queue
continuously. Since dirty queue mutex is not dropped, bufdone() in
g_up thread is starved, usually deadlocking the machine [2]. Mitigate
this by dropping the queue lock after the vnode is locked, allowing
other queue lock contenders to make a progress.

Allow the path to the system source directory to be passed in to
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.
Prevent the set -e from mk-osreldate.sh from propagating into newvers.sh.

Add driver for the PAPR VSCSI virtual SCSI controller. This lets FreeBSD

/sys/cam in the future to allow them to be used for IB storage. Thanks to
Scott Long for a great deal of implementation help.

identifier to the known SCSI transports for the SCSI RDMA protocol, as

Rework handling of ofw_quiesce(), making it the responsibility of the
platform modules. Whether to call this function or not is highly machine
dependent: on some systems, it is required, while on others it breaks

out. This is required for POWER hypervisor SCSI to work correctly. There
are no functional changes on Powermac systems.
Make sure that ref and changed bits propagate back to the VM layer

allow these to become stale.
Allow Open Firmware syscons to attach to devices without an "address"
