Uses of mallocarray(9).
The use of mallocarray(9) has rocketed the required swap to build FreeBSD.
This is likely caused by the allocation size attributes which put extra pressure
on the compiler.
Given that most of these checks are superfluous we have to choose better
where to use mallocarray(9). We still have more uses of mallocarray(9) but
hopefully this is enough to bring swap usage to a reasonable level.

Focus on code where we are doing multiplications within malloc(9). None of
these is likely to overflow, however the change is still useful as some
static checkers can benefit from the allocation attributes we use for
mallocarray.
This initial sweep only covers malloc(9) calls with M_NOWAIT. No good
reason but I started doing the changes before r327796 and at that time it
was convenient to make sure the sorrounding code could handle NULL values.

Since we have no control over the name, the MAKEDEV_CHECKNAME flag must be
used to return an error on an invalid (to devfs) name instead of panicing.
r305900 that originally added this feature also introduced a few other bugs:
- Proper locking not performed
- Theoretically broke the expectation that the control event buffer would
not span more than one pages, but did not update the CTASSERT that was
in place to prevent this. However, since the struct virtio_console_control
and the bulk buffer together were quite small, this could not have happened.
Also workaround an QEMU VirtIO spec violation in that it includes the NUL
terminator in the buffer length when the spec says it is not included.

Make virtio_console(4) create `/dev/vtcon/<port_name>` alias pointing
to /dev/ttyVx.y upon receiving PORT_NAME (id = 7) event over the control
queue.

Most affect comments, very few have user-visible effects.

- Support the KDB alt break sequence to enter the debugger,
panic, reboot, etc. [1]
- Provide emergency write feature description. Note that QEMU
does not implement this feature.
- Make the VTCON_FLAG_* defines sequential once again.
- When the multiple port feature is not negotiated, query the
rows and columns of the one console during the device attach
when the size feature is negotiated.
- Report failure to the device if hot plugging a port fails.
- Acknowledge the console port event with an open event. This
is required by the spec, but QEMU doesn't seem to care.

Support for the multiport feature is mostly implemented, but currently
disabled due to some potential races in the hot plug code paths.
