r363079 introduced the possibility of loading the SCTP stack as a module in
addition to compiling it into the kernel. As part of this, the registration
of the system calls was removed and put into the loading of the module.
Therefore, the system calls are not registered anymore when compiling the
SCTP into the kernel. This patch addresses that.

Old subscription model allowed only single customer.
Switch inet6 to the new subscription api and eliminate the old model.
Differential Revision: https://reviews.freebsd.org/D25615
Subscriptions are planned to be used by modules such as route lookup engines.
In that case that's the module task to properly unsibscribe before detach.
However, the in-kernel customer - inet6 wants to track default route changes.
To avoid having inet6 store per-fib subscriptions, handle automatic
destruction internally.

It is documented as a raw hardware-based clock not subject to NTP or
incremental adjustments. With this "not as precise as CLOCK_MONOTONIC"
description in mind, map it to our CLOCK_MONOTNIC_FAST (the same
mapping as for the linux CLOCK_MONOTONIC_COARSE).
This is needed for the webcomponent of steam (chromium) and some
other steam component or game.
The linux-steam-utils port contains a LD_PRELOAD based fix for this.
There this is mapped to CLOCK_MONOTONIC.
As an untrained ear/eye (= the majority of people) is normaly not
noticing a difference of jitter in the 10-20 ms range, specially
if you don't pay attention like for example in a browser session
while watching a video stream, the mapping to CLOCK_MONOTONIC_FAST
seems more appropriate than to CLOCK_MONOTONIC.
Linux processes these clocks in reverse order and some DT relies
on this fact. For example, the frequency setting for a given PLL
is the last in the list, preceded by the frequency setting of its
following divider or so...

The reason for this is to work around an idiosyncrasy of glibc
getttynam(3) implementation: it checks whether st_dev returned for
fd 0 is the same as st_dev returned for the target of /proc/self/fd/0
symlink, and with linux chroots having their own devfs instance,
the check will fail if you chrooted into it.

The change adds an SCTP mode akin to UDP mode. This is handy for doing
smoke testing of SCTP.
Use a long option to minimize the risk of option conflicts with OpenBSD.
For bonus points, this change unbreaks --no-tcpopt by adding a missing

This fixes a coredump with NetBSD guests when XHCI is configured.
On seeing the AC64 flag clear, the NetBSD XHCI driver was only writing
to the lower 32-bits of 64-bit physical address registers. The emulation
relies on a write to the hi 32-bits to calculate a host virtual address
for internal use, and has always supported 64-bit addressing.
All other guests were seen to write to both the lo- and hi- address
registers, regardless of the AC64 setting.
