Implement a small enhancement to the original qsort implementation:
If the data is 32 bit aligned we can side-step the long type
version and use int instead.
The change brings a modest but significant improvement in
32 bit workloads.

Passing through physical block size/offset from underlying storage allows

This fixes an issue where a FDT child node without a matching driver could
leave the GPIO pins mapped and prevent the further use of them.
This prints a warning when your system have a hinted child or a FDT child

-mno-align-long-strings when compiling with base gcc. This is checked
by comparing the version number against 4.2.1, which is not exactly
right, but good enough. (There is no other way to check whether we are
using the non-standard gcc in base, as far as I know.)

When several threads are trying to send datagram to the same destination,
but fragmentation is disabled and datagram size exceeds link MTU,
ip6_output() calls pfctlinput2(PRC_MSGSIZE). It does notify all
sockets wanted to know MTU to this destination. And since all threads
hold PCB lock while sending, taking the lock for each PCB in the
in6_pcbnotify() leads to deadlock.
RFC 3542 p.11.3 suggests notify all application wanted to receive
IPV6_PATHMTU ancillary data for each ICMPv6 packet too big message.
But it doesn't require this, when we don't receive ICMPv6 message.
Change ip6_notify_pmtu() function to be able use it directly from
ip6_output() to notify only one socket, and to notify all sockets
when ICMPv6 packet too big message received.

* Force the arge0 interface to not use a PHY for speed negotiation
for now. It'd be nice to do it, but right now the RGMII interface
to the switch needs to stay at 1000/full in order to match what
the switch side of the port is programmed as.
So until that's all sorted out, disconnect arge0 from the PHY
and leave it at fixed at 1000/full.
I noticed this when I tried using a busted ethernet cable that
forced the PHY to negotiate 100/full. The switch was fine and
it negotiated to 100/full, but then arge0 saw the link update
and set the speed to 100/full when the switch side of that
hook up was set to 1000/full. Tsk.
* When using argemdio, the mdio device resets and initialises
the MAC, /not/ the arge_attach (or, as I discovered, arge_init.)
So arge1 wasn't being fully initialised and thus no traffic
would ever flow.
So until I tidy up that mess, just create an argemdio bus for
arge1. It's totally fine; it won't do anything or find anything
attached to it.
Tested:
* AP135 reference board - both arge0 and arge1 now work.

Additionally, add the --not-running-from-cron flag they bypasses the TTY requirement, and allows freebsd-update to be invoked by orchestration frameworks, scripts, or otherwise.

As it turns out, the density code for DAT-160 (0x48) is the same
as for SDLT220. Since the SDLT values are already in the table,
we will leave them in place.
Thanks to Harald Schmalzbauer for confirming the DAT-72 density code.
