The bulk stats functions are specific as they pass around the list into
many sub-functions and also a substantial amount of the entries uses
formatted names for indexing purposes. This makes them ideal to be
converted to the new virTypedParamList helpers.
Unfortunately given how the functions are used this requires a big-bang
rewrite of all of the calls to add entries to the parameter list.
Given that a substantial simplification is achieved as well as a pretty
significant change to the original code is required some macros which
were used only sporadically were replaced by inline calls rather than
tweaking the macros first and deleting them later.

None of the fields actually return negative values. The internal
implementation of BlockAcctStats struct in qemu uses uint64_t and the
last place using -1 in libvirt was in the HMP monitor code which was
deleted.
Change the internal type to unsigned long long and ensure that all
public conversions don't overflow.

Introduce a new set of helpers including a new data structure which
simplifies keeping and construction of lists of typed parameters.
The use of VIR_RESIZE_N in the virTypedParamsAdd API has performance
benefits but requires passing around 3 arguments. Use of them lead to a
set of macros with embedded jumps used in the qemu statistics code.
This patch introduces 'virTypedParamList' type which aggregates the
necessary list-keeping variables and also a new set of functions to add
new typed parameters to a list.
These new helpers use printf-like format string and arguments to format
the argument name as the stats code often uses indexed typed parameters.
The accessor function then allows extracting the typed parameter list in
the same format as virTypedParamsAdd* functions would do.
One additional benefit is also that the list function can easily be used
with VIR_AUTOPTR.

Some of the typed parameter APIs are exported publicly, but the
implementation was intermixed with private functions. Introduce
virtypedparam-public.c, move all public API functions there and purge
the comments stating that some functions are public.
This will decrease the likelihood of messing up the expectations as well
as it will become more clear which of them are actually public.

Turns out, block mirror is not the only job a disk can have. It
can also do commits of one layer into the other. Or possibly some
other tricks too. Problem is that while we set seclabels on given
layers of backing chain when the job is starting (via
qemuDomainStorageSourceAccessAllow()) we don't restore them when
job finishes. This leaves XATTRs set and corresponding images
unusable.

In bc1e924cf0 we've introduced video driver name and whilst
doing so we've utilized VIR_ENUM_IMPL() macro. Then, in domain
XML parsing code the generated
virDomainVideoBackendTypeFromString() is called and its return
value is assigned directly to an unsigned int variable which is
wrong. Also, the video driver enum has 'default' value which is
not formatted into domain XML but is accepted during parsing.

Semantically VIR_DOMAIN_START_AUTODESTROY doesn't really clash with
snapshot operations as the VM stays on the same host and thus bound to

Semantically we can't guarantee that we'll be able to destroy the VM on

of migration (e.g. saving to file) are okay though as they don't clash

Apart from migrating the VM to a remote host where we can't honour the
VIR_DOMAIN_START_AUTODESTROY flag properly, restricting APIs which just
modify the state of the VM does not make much sense.
Change the wording of the documentation for VIR_DOMAIN_START_AUTODESTROY
so that snapshots and saving to a file may be permitted as they
semantically don't clash with the flag itself. Otherwise we'd have to
forbid other APIs, such as virDomainDestroy as well.

Python3 >= 3.7 now assumes that the C locale is always UTF-8.

we get UTF-8 handling on all python versions. Note we do
