Update the regex for the slirp component now that it lives
solely inside /slirp/, and note that it should be ignored in
Coverity analysis (because it's a separate upstream project
now, and they run Coverity on it themselves).

9e8be4c546 drop libxml2 checks since libxml is not actually used (for parallels)
For a long time, we assumed that libxml2 is necessary for parallels
block format support (block/parallels*). However, this format actually
does not use libxml [*]. Since this is the only user of libxml2 in
whole QEMU tree, we can drop all libxml2 checks and dependencies too.

It is even more: --enable-parallels configure option was the only
option which was silently ignored when it's (fake) dependency
(libxml2) isn't installed.

Drop all mentions of libxml2.

[*] Actually the basis for libxml use were introduced in commit
    ed279a06c5 ("configure: add dependency") but the implementation
    was never merged:

a5730b8bd3 block/file-posix: Simplify the XFS_IOC_DIOINFO handling
The handling for the XFS_IOC_DIOINFO ioctl is currently quite excessive:
This is not a "real" feature like the other features that we provide with
the "--enable-xxx" and "--disable-xxx" switches for the configure script,
since this does not influence lots of code (it's only about one call to
xfsctl() in file-posix.c), so people don't gain much with the ability to
disable this with "--disable-xfsctl".
It's also unfortunate that the ioctl will be disabled on Linux in case
the user did not install the right xfsprogs-devel package before running
configure. Thus let's simplify this by providing the ioctl definition
on our own, so we can completely get rid of the header dependency and
thus the related code in the configure script.

e17bdaab2b coverity-model: write models fully for non-array allocation functions
Coverity seems to have issues figuring out the properties of g_malloc0
and other non *_n functions.  While this was "fixed" by removing the
custom second argument to __coverity_mark_as_afm_allocated__, inline
the code from the array-based allocation functions to avoid future
issues.

0da41187df coverity-model: constrain g_malloc/g_malloc0/g_realloc as never returning NULL
g_malloc/g_malloc0/g_realloc only return NULL if the size is 0; we do not need
to cover that in the model, and so far have expected __coverity_alloc__
to model a non-NULL return value.  But that apparently does not work
anymore, so add some extra conditionals that invoke __coverity_panic__
for NULL pointers.

243a545bff coverity-model: make g_free a synonym of free
Recently, Coverity has started complaining about using g_free() to free
memory areas allocated by GLib functions not included in model.c,
such as g_strfreev.  This unfortunately goes against the GLib
documentation, which suggests that g_malloc() should be matched
with g_free() and plain malloc() with free(); since GLib 2.46 however
g_malloc() is hardcoded to always use the system malloc implementation,
and g_free is just "free" plus a tracepoint.  Therefore, this
should not cause any problem in practice.

fbb84f0741 run-coverity-scan: support --update-tools-only --docker
Just build the container when run-coverity-scan is invoked with
--update-tools-only --docker.  This requires moving the "docker build"
logic into the update_coverity_tools function.

The only snag is that --update-tools-only --docker requires access to
the dockerfile.  For now just report an error for --src-tarball, and
"docker build" will fail if not in a source tree.  Another possibility
could be to host our container images on a public registry, and use
"FROM qemu:fedora" to make the Dockerfile small enough that it can be
included directly in the run-coverity-scan script.

For the "run" phase this is transparent; for the "build" phase however
scripts are replaced with a bind mount (-v).  This is not an issue
because the secret option is meant for secrets stored globally in the
system and bind mounts are a valid substitute for secrets that are known
