cons: Add boot option to mute boot messages after banner
This is useful for embedded systems, where it provides feedback that the
kernel has booted, but avoids printing the probe messages. If both
mutemsgs and verbose are set, verbose cancels the mute.
Additionally, this unmutes the console on panic, so a user can see what
happened leading up to the panic.

cxgbe(4): Do not read hardware registers to determine the number of ports.
PORTVEC obtained from the firmware is the authoritative source of this
information, and nports (calculated from PORTVEC) is available by the
time t4_port_init runs.

Fix new users of MAXPHYS and hide it from the kernel namespace
In cd8537910406, kib made maxphys a load-time tunable. This made
the #define MAXPHYS in sys/param.h almost entirely obsolete, as
it could now be overridden by kern.maxphys at boot time, or by
opt_maxphys.h.
However, decades of tradition have led to several new, incorrect, uses
of MAXPHYS in other parts of the kernel, mostly by seasoned
developers. I've corrected those uses here in a mechanical fashion,
and verified that it fixes a bug in the md driver that I was
experiencing.
Since using MAXPHYS is such an easy mistake to make, it is best to
hide it from the kernel namespace. So I've moved its definition to
_maxphys.h, which is now included in param.h only for userspace.
That brings up the fact that lots of userspace programs use MAXPHYS
for different reasons, most of them probably wrong. Userspace consumers

All the channels are not used on all boards and there's no point

libsys: don't try to expose freebsd7___semctl
This has always been in libc and never exported directly. I accidently
included it along side some freebsd11_* symbols based on a tree where I
moved semctl(2).

vm: Fix error handling in vm_thread_stack_back()
vm_object_page_remove() wants to busy the page, but that won't work
here. (Kernel stack pages are always busy.)
Make the error handling path look more like vm_thread_stack_dispose().

Remove remnants of portsnap(8)
This was prompted by noticing that '/var/db/portsnap' still exists on
newly-installed machines.
With this change, all mentions of portsnap(8) in the tree are gone,
except for the historical note in the AUTHORS section of manpage
phttpget(8).
locate(1) will thus start indexing again '/var/db/portsnap' on machines
where this directory still exists, which may be a good way to push
administrators to delete it.
