e9cfbd36c5 tests: fix stat mocking with Fedora rawhide
GLibC has a really complicated way of dealing with the 'stat' function
historically, which means our mocks in turn have to look at four
different possible functions to replace, stat, stat64, __xstat,
__xstat64.

In Fedora 33 and earlier:

 - libvirt.so links to __xstat64
 - libc.so library exports stat, stat64, __xstat, __xstat64
 - sys/stat.h header exposes stat and __xstat

In Fedora 34 rawhide:

 - libvirt.so links to stat64
 - libc.so library exports stat, stat64, __xstat, __xstat64
 - sys/stat.h header exposes stat

Historically we only looked at the exported symbols from libc.so to
decide which to mock.

In F34 though we must not consider __xstat / __xstat64 though because
they only existance for binary compatibility. Newly built binaries
won't reference them.

Thus we must introduce a header file check into our logic for deciding
which symbol to mock. We must ignore the __xstat / __xstat64 symbols
if they don't appear in the sys/stat.h header, even if they appear
in libc.so

c7fa462a87 meson: remove non-pkg-config fallback for devmapper
The fallback for distros which lack pkg-config support for devmapper
references an undefined variable "tmp". It appears non of our supported
build platforms are triggering this bug and so the fallback code can be
removed entirely rather than fixed.

c6c2341570 build: remove duplicate check for GET_VLAN_VID_CMD
Somehow this check was duplicated just below the original.

(I was at first skeptical that it's needed at all, since
GET_VLAN_VID_CMD was already present in kernel 2.6.32, but then I
realized that there is no higher level check for __linux__ around the
code that is conditional on WITH_DECL_GET_VLAN_VID_CMD; it only checks
for SIOCGIFVLAN and WITH_STRUCT_IFREQ - the latter is also present on
*BSD platforms, the former doesn't seem to be anywhere but Linux, but
I didn't want to change the effect of the conditional, so I left it in
(we could have also replaced WITH_DECL_GET_VLAN_VID_CMD, but possibly
there is a non-Linux platform that *does* have it...)

7556ab139f build: eliminate WITH_MACVTAP flag entirely
This flag was originally created to indicate that either 1) the build
platform wasn't linux, 2) the build platform was linux, but the kernel
was too old to have macvtap support. Since there was already a switch
there, the ability to also disable it when 3) the kernel supports
macvtap but the user doesn't want it, was added in. I don't think that
(3) was ever an intentional goal, just something that grew naturally
out of having the flag there in the first place (unless possibly the
original author wanted a way to quickly disable their new code in case
it caused regressions elsewhere).

Now that the check for (2) has been removed, WITH_MACVTAP is just
checking (1) and (3), but (3) is pointless (because the extra code in
libvirt itself is miniscule, and the only external library needed for
it is libnl, which is also required for other unrelated features (and
itself has no subordinate dependencies and takes up < 1MB on
disk)). We can therfore eliminate the WITH_MACVTAP flag, as it is
functionally equivalent to WITH_LIBNL (which implies __linux__).

0cbce414e4 build: simplify check for WITH_MACVTAP
macvtap support was added to the Linux kernel in 2.6.33. libvirt
checked for this by looking for MACVLAN_MODE_BRIDGE and IFLA_VF_MAX in
linux/if_link.h. This hasn't been necessary for a very long time, so
just gate on platform == 'linux' (and be sure to complain if someone
tries to enable it on a non-Linux platform).

a79e7639da build: eliminate useless WITH_VIRTUALPORT check
WITH_VIRTUALPORT just checks that we are building on Linux and that
IFLA_PORT_MAX is defined in linux/if_link.h. Back when 802.11Qb[gh]
support was added, the IFLA_* stuff was new (introduced in kernel
2.6.35, backported to RHEL6 2.6.32 kernel at some point), and so this
extra check was necessary, because libvirt was being built on Linux
distros that didn't yet have IFLA_* (e.g. older RHEL6, all
RHEL5). It's been in the kernel for a *very* long time now, so all
supported versions of all Linux platforms libvirt builds on have it.

Note that the above paragraph implies that the conditional compilation
should be changed to #if defined(__linux__). However, the astute
reader will notice that the code in question is sending and receiving
netlink messages, so it really should be conditional on WITH_LIBNL
(which implies __linux__) instead, so that's what this patch does.

2ef84f000f util: introduce helpers for GLib DBus implementation
With libdbus our wrappers had a special syntax to create the DBus
messages by defining the DBus message signature followed by list
of arguments providing data based on the signature.

There will be no similar helper with GLib implementation as they
provide same functionality via GVariant APIs. The syntax is slightly
different mostly for how arrays, variadic types and dictionaries are
created/parsed.

Additional difference is that with GLib DBus everything is wrapped in
extra tuple (struct). For more details refer to the documentation [1].

de3289e2b5 remove HAL node device driver
There was one attempt a year ago done by me to drop HAL [1] but it was
never resolved. There was another time when Dan suggested to drop HAL
driver [2] but it was decided to keep it around in case device
assignment will be implemented for FreeBSD and the fact that
virt-manager uses node device driver [3].

I checked git history and code and it doesn't look like bhyve supports
device assignment so from that POV it should not block removing HAL.

The argument about virt-manager is not strong as well because libvirt
installed from FreeBSD packages doesn't have HAL support so it will not
affect these users as well [4].

The only users affected by this change would be the ones compiling
libvirt from GIT on FreeBSD.

I looked into alternatives and there is libudev-devd package on FreeBSD
but unfortunately it doesn't work as it doesn't list any devices when
used with libvirt. It provides libudev APIs using devd.

I also looked into devd directly and it provides some APIs but there are
no APIs for device monitoring and events so that would have to be
somehow done by libvirt.

Main motivation for dropping HAL support is to replace libdbus with GLib
dbus implementation and it cannot be done with HAL driver present in
libvirt because HAL APIs heavily depends on symbols provided by libdbus.

caa9560c15 wireshark: Prefer ws_version.h over config.h
A wireshark plugin must declare what major and minor version it
was built with as these are checked when wireshark loads plugins.
On the top of that, we use major + minor + micro to adapt to
changed API between releases. So far, we were getting these
version numbers from wireshark/config.h.

And while most distributions install wireshark/config.h file some
don't. On distros shipping it it's hack^Wsaved during built by
packaging system and installed later. But some distros are not
doing that. At least not for new enough wireshark because as of
wireshark's commit v2.9.0~1273 the ws_version.h is installed
which contains the version macros we need and is installed by
wireshark itself.

But of course, some distros which have new enough wireshark
packaged do not ship ws_version.h and stick to the hack. That is
why we can't simply bump the minimal version and switch to the
new header file. We need a configure check and adopt our code to
deal with both ways. At least for the time being.

028d6c0513 meson: add -Wall and -Wextra explicitly
If someone runs `meson setup --buildtype plain` meson ignores
warning_level=2 that is in our meson.build file. The implication is
that Meson will not automatically add -Wall which enables -Wformat.

This breaks building libvirt from git with the buildtype set to plain.

There is an issue reported [1] to not ignore warning_level silently
and the change to ignore it was done by upstream commit [2].

This change makes Meson print warnings about using warning_level which
as described above doesn't work for all build types.

84bb5fd1ab meson: fix readline detection if there is no pkg-config file
Commit <74416b1d4849ef77ef31de5344dd75f03094434b> added check for
rl_completion_quote_character to make sure we have correct readline
library. Commit <a9443bc9a9ef451b46306e66ed3b706756fc1414> added
inaccurate comment that it's a function.

We need to check for generic symbol instead of checking for function.
In addition the readline/readline.h file requires stdio.h to by included
beforehand which was done in autotools but I dropped it in meson.

And lastly the final condition to print error or disable readline was
broken as well by replacing the readline_dep every time if readline was
not explicitly enabled.
