Libvirt switched to using a UNIX socket for monitors in
2009 for version 0.7.0. It seems unlikely that there is
a running QEMU process that hasn't been restarted for
11 years while also taking a libvirt upgrade. Therefore
we can drop support for opening a PTY for the QEMU
monitor.

On FreeBSD 12 the default ulimit settings allow for 100,000
open file descriptors. As a result spawning processes in
libvirt is abominably slow. Fortunately FreeBSD has long
since provided a good solution in the form of closefrom(),
which closes all FDs equal to or larger than the specified
parameter.

When emulating smartcard with host certificates, qemu needs to
be able to read the certificates files. Add necessary code to
add the smartcard certificates file path to the apparmor profile.

Passthrough support has been tested with spicevmc and remote-viewer.

v2:
- Fix CodingStyle
- Add support for 'host' case.
- Add a comment to mention that the passthrough case doesn't need
  some configuration
- Use one rule with '{,*}' instead of two rules.

Users expect to be able to configure the <console> element and see
that configuration reflected into the <serial> element or at least
sticking, however due to our crazy back-compat code that doesn't
always happen.

There's really not much we can do to make this kind of corner cases
work as the user would expect, especially not without introducing
additional complexity in a part of libvirt that already has more
than a fair share of it; we can, however, improve the documentation
so that it will nudge said users in the right direction.

Our virCommand helper API already has the ability to capture
program output, there's no need to open-code it.

Apart from simplifying the code, the test is marginally faster
due to recent improvements in virCommandMassClose.

Until now, both stderr and stdout were stored in the same buffer.
This change stores stderr separately and expects it to be empty
for all the tests we currently run.
