Users expect to be able to configure the <console> element and see

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.

Simplify gathering the actual return value from a passed-through QMP
command when using 'qemu-monitor-command' by adding '--return-value'
switch which just extracts the 'return' section and alternatively
reports an error if the section is not present.
This simplifies gathering of some test data where the full reply would
need to be trimmed just for the actual return value.

This deletes all trace of gnulib from libvirt. We still
have the keycodemapdb submodule to deal with. The simple
solution taken was to update it when running autogen.sh.
Previously gnulib could auto-trigger refresh when running
'make' too. We could figure out a solution for this, but
with the pending meson rewrite it isn't worth worrying
about, given how infrequently keycodemapdb changes.
