Most code now uses the virProcess / virCommand APIs, so
the need for sys/wait.h is quite limited. Removing this
include removes the dependency on GNULIB providing a
dummy sys/wait.h for Windows.

The current event loop test suite has two threads running
in lockstep. This was just about viable when we have full
control over the internal details of the event loop impl.
When we're using the GLib event loop though there are
things going on that we don't know about, such as use of
eventfd() file descriptors. This will break the assumptions
in the test suite, causing non-deterministic failures.
This change switches the event loop thread to run fully
asynchronously from the test suite cases. This is slightly
weaker validation, but the only way we can get a reliable
test suite.

The event test directly calls the internal poll event impl
APIs. It does not rely on any specific details of the poll

Reviewed-by: Ján Tomko <jtomko@redhat.com>
Add a validator which checks that a bitmap spanning multiple backing
chain members doesn't look broken. The current rules are that no
intermediate birmaps are missing (unfortunately it's hard to know
whether the topmost or bottommost bitmap is missing) and none of the
components is inconsistent.
We can obviously improve it over time.
The validator is also tested against the existing bitmap data we have
for the backup merging test as well as some of the existing broken
bitmap synthetic test cases.

Struct lxcNetworkParseData is being used as a single pointer which
iterates through LXC config lines. It means that it will be applied as a
network each time that a new type appears. After, the same struct is
used to populate a new network interface. This commit changes this logic
to multiple lxcNetworkParseData to move this strcuture to an array. It
makes more sense if we are using indexes to fill interface settings.
This is better to improve code clarity.
