914cb83218 conf: Add support for tpm-spapr to domain XML
This patch adds support for the tpm-spapr device model for ppc64. The XML for
this type of TPM looks as follows:

 <tpm model='tpm-spapr'>
   <backend type='emulator'/>
 </tpm>

Extend the documentation.

21b6f41d95 conf: Introduce VIR_DOMAIN_TPM_MODEL_DEFAULT as default model
Introduce VIR_DOMAIN_TPM_MODEL_DEFAULT as a default model which we use
in case the user does not provide a model in the device XML. It has
the TIS's previous value of '0'. In the post parsing function
we change this default value to 'TIS' to have the same model as before.

11a79283b8 src: ensure use of g_printf / g_fprintf functions
The printf/fprintf function impls provided on Windows do
not follow the normal syntax for format specifiers as
the UNIX hosts. Currently we use GNULIB to provide a
portability fix for this. GLib has also imported the
GNULIB impl for this same reason, and thus we can rely
on the g_printf / g_fprintf functions.

This identified a couple of places not explicitly
linking to glib.

32363452af tests: refactor event test to not run lock step
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.

Add a validator which checks that a bitmap spanning multiple backing

We can obviously improve it over time.

The validator is also tested against the existing bitmap data we have

bitmap synthetic test cases.
