rc: virtual_oss: Wait for process to exit

Sometimes virtual_oss processes do not exit immediatelly. If we do not
wait for the processes to fully exit before returning from
virtual_oss_stop(), then the service restart operation might call
virtual_oss_start() too early and fail, because it will think the
service wasn't stopped and is still running.

virtual_oss: Introduce virtual_oss_default_control_device rc variable

The -t option gives the user the ability to create a control device for
a given virtual_oss(8) instance, so that the instance's configuration
can be manipulated during runtime with virtual_oss_cmd(8). As is
expected, the control device's name is not known, since it is specified
by the user.

This patch introduces a virtual_oss_default_control_device rc variable,
which defaults to "vdsp.ctl". The goal of this is that third-party
programs and scripts can access the control device of the default
virtual_oss(8) configuration without guessing. This is especially useful
for sbin/devd/snd.conf which deals with hot-swapping sound devices using
virtual_oss(8).

virtual_oss: Port to base

This patch diverges quite a bit from the current upstream [1] in a few
ways:

1. virtual_oss(8), virtual_bt_speaker(8) and virtual_oss_cmd(8) are
actually separate programs.
2. Backends (lib/virtual_oss) are built as separate shared libraries and
we dlopen() them in virtual_oss(8) and virtual_bt_speaker(8) on
demand.
3. virtual_equalizer(8) and the sndio and bluetooth backends are built
as ports, because they depend on third-party libraries.
4. Use newer libav API in bluetooth backend (see HAVE_LIBAV ifdefs) to
address compiler errors.
