Similar to how other objects arrange their parse APIs. This will be
used by the test driver.

Right now things are split a bit between parsing from a relative file
path or parsing from inline XML. Unify it. This will simplify upcoming
bits.

Passing virConnectPtr is redundant, just pass testConnPtr and simplify
certain callers.

The function that parses custom driver XML was getting pretty unruly,
split the object parsing into their own functions. Rename some variables
to be consistent across each function. This should be functionally
identical.

Currently the virConnectBaselineCPU API does not expose the CPU features
that are part of the CPU's model.  This patch adds a new flag,
VIR_CONNECT_BASELINE_CPU_EXPAND_FEATURES, that causes the API to explicitly
list all features that are part of that model.

Cleanup the libxl capabilities code to be a bit more extensible,
splitting out the creation of host and guest capabilities.  This
should make it easier to implement additional capabilities in the
future, such as NUMA topology reporting.

Feedback from the polkit developers indicates that the
"_detail_XXXX" attributes are a private implementation
detail. Our examples should be recommending use of the
"action.lookup('XXX')" method instead.

Previous patch fixed an issue where, when parsing a bitmap from the
string, the bounds of the bitmap weren't checked. That flaw resulted into
crashes. This test tests that case to avoid it in the future.

The virBitmapParse function was calling virBitmapIsSet() function that
requires the caller to check the bounds of the bitmap without checking
them. This resulted into crashes when parsing a bitmap string that was
exceeding the bounds used as argument.

This patch refactors the function to use virBitmapSetBit without
checking if the bit is set (this function does the checks internally)
and then counts the bits in the bitmap afterwards (instead of keeping
track while parsing the string).

This patch also changes the "parse_error" label to a more common
"error".

The refactor should also get rid of the need to call sa_assert on the
returned variable as the callpath should allow coverity to infer the
possible return values.

Gnulib recently patched gcc warning detection so that it does
not treat things like -Wno-unused-command-line-argument as
supported in gcc (treating it as supported merely resulted in
extra verbosity when an actual compile error occurred).  It
has also improved bootstrap to work with less hassle on OpenBSD.

I noticed that in a fresh checkout, autogen.sh generated the
following output, but continued on with execution:

autoreconf: running: automake --add-missing --copy --force-missing
gnulib/tests/Makefile.am:28: TESTS was already defined in condition TRUE, which includes condition WITH_EXPENSIVE_TESTS ...
gnulib/tests/gnulib.mk:28: ... `TESTS' previously defined here
gnulib/tests/Makefile.am:19:   `gnulib/tests/gnulib.mk' included from here

and after the run, line 28 of gnulib.mk lists GNULIB_TESTS, not TESTS.
After more investigation, I found that it is because gnulib bootstrap
provides two hooks, one before automake, and the other after; we used
the one that ran after, and were then rerunning automake ourselves;
and the warning was from the first run.  But a manual second run is
pointless if we use the right hook in the first place.

The wrong function name has been latent since commit 38c9440a, and we
tried to work around it in commit 6cbab7c1, but it took commit 70363ea9
to finally change output enough for me to realize the root cause.

There is a potential leak of a newly created libxlDomainObjPrivate

Unref the object on such an error so that it is properly disposed.

libvirt the name and path strings weren't freed properly.

This resolves the issue that prompted the filing of

  https://bugzilla.redhat.com/show_bug.cgi?id=928638

(although the request there is for something much larger and more
general than this patch).

commit f3868259 disabled the
forwarding to upstream DNS servers of unresolved DNS requests for
names that had no domain, but were just simple host names (no "."
character anywhere in the name). While this behavior is frowned upon
by DNS root servers (that's why it was changed in libvirt), it is
convenient in some cases, and since dnsmasq can be configured to allow
it, it must not be strictly forbidden.

This patch restores the old behavior, but since it is usually
undesirable, restoring it requires specification of a new option in
the network config. Adding the attribute "forwardPlainNames='yes'" to
the <dns> elemnt does the trick - when that attribute is added to a
network config, any simple hostnames that can't be resolved by the
network's dnsmasq instance will be forwarded to the DNS servers listed
in the host's /etc/resolv.conf for an attempt at resolution (just as
any FQDN would be forwarded).

When that attribute *isn't* specified, unresolved simple names will
*not* be forwarded to the upstream DNS server - this is the default
behavior.

The virtlockd/libvirtd daemons had listed '?' as the short option
for --help. getopt_long uses '?' for any unknown option. We want
to be able to distinguish unknown options (which use EXIT_FAILURE)
from correct usage of help (which should use EXIT_SUCCESS). Thus
we should use 'h' as a short option for --help. Also add this to
the man page docs

The virtlockd/libvirtd daemons did not list any short option
for the --version arg. Add -V as a valid short option, since
-v is already used for --verbose.

I noticed this yesterday and fixed it in a different way, but ended up
with one more problem.  It was probably the way I fixed it combined
with one more filename changed.

Anyway, why I'm saying this is that one more filename should be renamed
in order to avoid a race (which I was unable to reproduce, though).

I checked this is the last file those two tests have in common by going
through the code and the re-checked by this "script":

strace -o session.trace -e open ./virnettlssessiontest
strace -o context.trace -e open ./virnettlscontexttest
sort \
 <(sed -n '/^open/s/open("\([^"]*\)",.*$/\1/p' context.trace | sort -u)\
 <(sed -n '/^open/s/open("\([^"]*\)",.*$/\1/p' session.trace | sort -u)\
 | uniq -d| grep '.pem$'

So it should be enough to make these tests independent of each other.
