Instead of having each test manually initialize and cleanup
its own fakerootdir, do that as part of the common test
initialization logic in virTestMain().
In most cases we can simply drop the relevant code from the
test program, but scsihosttest uses the value of fakerootdir
as a starting point to build another path, so we need to do
things slightly differently. In order to keep things working,
we retrieve the value from the LIBVIRT_FAKE_ROOT_DIR
environment variable, same as all the mock libraries are
already doing.

Most replacements are completely straightforward but
vircgrouptest requires slightly different handling because,
instead of initializing a single fakerootdir at the start of
the test program and cleaning it up at the end, it creates
multiple different ones one after the other.

Our code uses fdsets for the pipe passed from virtlogd to qemu, but the

Historically, we declared pointer type to our types:
typedef struct _virXXX virXXX;
typedef virXXX *virXXXPtr;
But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

Turns out that it's not enough to pass the qemu:///embed root to
virQEMUDriverConfigNew(), you also have to make sure the same
string is copied into the virQEMUDriver structure yourself, and
not doing so in our case resulted in the cleanup never happening
and in distcheck failing because of that.
On the other hand, actually setting config->embeddedRoot would
result in different paths being generated for each test run, which
would obviously break qemuxml2argvtest, so that's not an option
either.

The qemuMonitorTestNew() function returns with the monitor object
locked, and expects it to still be locked when qemuMonitorTestFree
is called. The qemuhotplug test, however, explicitly unlocks the
monitor, but then forgets to lock it again. As a result the
qemuMonitorTestFree function is unlocking a mutex it doesn't own.
This bug has existed forever, but since we use normal POSIX mutexes
and don't check the return value of pthread_mutex_lock/unlock we
didn't see the error. It was harmless until the switch to the per
monitor event loop which requires the thread synchronization to
work reliably, whereupon it started crashing.
