Python3 versions less than 3.7 have very unhelpful handling
of the C locale where they assume data is 7-bit only. This
violates POSIX which requires the C locale to be 8-bit clean.
Python3 >= 3.7 now assumes that the C locale is always UTF-8.
Set env variables to force LC_CTYPE to en_US.UTF-8 so that
we get UTF-8 handling on all python versions. Note we do
not use C.UTF-8 since not all C libraries support that.

Many drivers had a comment that they did not validate the incoming
'flags' to virDomainGetXMLDesc() because they were relying on
virDomainDefFormat() to do it instead. This used to be the case
(at least since 461e0f1a and friends in 0.9.4 added unknown flag
checking in general), but regressed in commit 0ecd6851 (1.2.12),
when all of the drivers were changed to pass 'flags' through the
new helper virDomainDefFormatConvertXMLFlags(). Since this helper
silently ignores unknown flags, we need to implement flag checking
in each driver instead.
Annoyingly, this means that any new flag values added will silently
be ignored when targeting an older libvirt, rather than our usual
practice of loudly diagnosing an unsupported flag. Add comments
in domain_conf.[ch] to remind us to be extra vigilant about the
impact when adding flags (a new flag to add data is safe if the
older server omitting the requested data doesn't break things in
the newer client; a new flag to suppress data rather than enhancing
the existing VIR_DOMAIN_XML_SECURE may form a data leak or even a
security hole).
In the qemu driver, there are multiple callers all funnelling to
qemuDomainDefFormatBufInternal(); many of them already validated
flags (and often only a subset of the full set of possible flags),
but for ease of maintenance, we can also check flags at the common
helper function.

Currently, the functions return a pointer to the
destination buffer on success or NULL on failure.
Not only does this kind of error handling look quite
alien in the context of libvirt, where most functions
return zero on success and a negative int on failure,
but it's also somewhat pointless because unless there's
been a failure the returned pointer will be the same
one passed in by the user, thus offering no additional
value.
Change the functions so that they return an int
instead.

Re-generating of generated source files in the hyperv directory

timestamp older than src/hyperv/hyperv_wmi_generator.py. "make
maintainer-clean" erases the generated files, but not this sentinel
file, so the erased files aren't regenerated during the next
make. Once we add it to the list of MAINTAINERCLEANFILES, it gets
deleted at the same time as the generated files, so make is able to

Hyper-V uses its own specific memory management so no mapping is going to
be perfect. However, it is more correct to map Limit to max_memory (it
really is the upper limit of what the VM may potentially use) and keep
cur_balloon equal to total_memory.
The typical value returned from Hyper-V in Limit is 1 TiB, which is not
really going to work if interpreted as "startup memory" to be ballooned
away later.

already set a meaningful error message at that point).

Slight refactor of the WMI serialization code to minimize mixing

The only usage of libxml2 APIs now is in creating CDATA blocks,
because the openwsman API does not provide that functionality. The
clang alignment warning in this case is silenced by casting to a
void pointer first.
