amdtemp(4): Add support for Family 17h temperature sensor
The sensor value is formatted similarly to previous models (same

co-processor.

Add smn(4) driver for AMD System Management Network
AMD Family 17h CPUs have an internal network used to communicate between
the host CPU and the PSP and SMU coprocessors. It exposes a simple
32-bit register space.
Make root_mount_rel(9) ignore NULL arguments, like it used to before r313351.
It would be better to fix API consumers to not pass NULL there - most of them,
such as gmirror, already contain the neccessary checks - but this is easier
and much less error-prone.
One known user-visible result is that it fixes panic on a failed "graid label".

Merge pipes and socket pairs.
Now that CloudABI's sockets API has been changed to be addressless and
only connected socket instances are used (e.g., socket pairs), they have
become fairly similar to pipes. The only differences on CloudABI is that
socket pairs additionally support shutdown(), send() and recv().
To simplify the ABI, we've therefore decided to remove pipes as a
separate file descriptor type and just let pipe() return a socket pair
of type SOCK_STREAM. S_ISFIFO() and S_ISSOCK() are now defined
identically.

Fix loader bug causing too many pages allocation when bootloader is U-Boot
FreeBSD loader expects to have mmsz variable set by bootloader.
U-Boot behaviour is that if buffer size is not big enough to keep
whole memory map, assign the smallest correct buffer size to sz
and return error.
In other words U-Boot assumes that nobody will need mmsz value when buffer
is not filled with memory map, which is not true, so calculated pages value
was too big to allocate.
