For head/, this will remain eternally default-on to maintain the status quo.
For stable/ branches, it should be flipped to default-off to maintain the
status quo.
There's value in being able to flip it one way or the other easily on head
or stable branches, whether you want to gain some performance back on head/
(for machines there's little chance you'll actually hit an assertion) or
potentially diagnose a problem with the version of llvm on an older branch.
Currently, stable branches get the CFLAGS+= -ndebug line uncommented; going
forward, they will instead have the default of LLVM_ASSERTIONS flipped.

Without this patch, the xid used for the client side krpc requests over
UDP was initialized for each "connection". A "connection" for UDP is
rather sketchy and for the kernel NLM a new one is created every 2minutes.
A problem with client side interoperability with a Netapp server for the NLM
was reported and it is believed to be caused by reuse of the same xid.
Although this was never completely diagnosed by the reporter, I could see
how the same xid might get reused, since it is initialized to a value
based on the TOD clock every two minutes.
I suspect initializing the value for every "connection" was inherited from
userland library code, where having a global xid was not practical.
However, implementing a global "xid" for the kernel rpc is straightforward
and will ensure that an xid value is not reused for a long time. This
patch does that and is hoped it will fix the Netapp interoperability
problem.

Notably, the default IFS contains space/tab, thus any leading/trailing
whitespace characters tend to be removed.
Set IFS= for just the read lines to mitigate this, allowing the user to be
less surprised when their leading/trailing spaces weren't actually captured
in the password as they are with other means of setting a user's password.

Prepare the ground for a rework of the bridge locking approach. We will
use an epoch-based approach in the datapath and making it safe to
iterate over the interface, span and rtnode lists without holding the
BRIDGE_LOCK. Replace the relevant lists by their ConcurrencyKit
equivalents.

The reporter is developing a frame buffer driver for hardware using
3 bytes per pixel, but a stride that's a multiple of 256. Previously
this resulted in writing beyond the end of each stride. On the last

In the FreeBSD base system we do not have Python support in lldb, but
will have Lua support. Make Lua the default.
This needs to be made into a configure-time option; that is being
discussed upstream and will appear in a future lldb import. For now
carry this change as a tiny patch to our copy of lldb.
Also, print a little more information for otherwise unhandled inhibited states.
Finally, improve the grammar of some prints. Some of the print statements
