As advertised in previous commits, wireshark has changed the way
that plugins register. In fact, it has done so two times since
the last time we've touched our code (wireshark v2.5.0 and
v2.9.0). Use the wireshark script from respective releases to
generate newer registration callbacks and put them into our code.

In order to be able to dissect libvirt protocol the wireshark
plugin needs to be registered. So far this plugin registration
code was generated on every build using a script that was copied
over from wireshark's tools/ directory.
This is suboptimal, because the way that plugins register changes
across wireshark releases. Therefore, let's keep the generated
file in the git, put the command line used to generate the file
into a comment and remove the script.
This solution allows us to put different registration mechanism
into one file (under #ifdef-s) and thus compile with wider range
of wireshark releases.

In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.
In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.
With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to find the
author of a particular bit of code.
This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.
The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.

Commit 4f4c3b13 (v3.3) fixed an issue where performing cleanup of
libvirt objects could sometimes lose error messages, by adding code
to copy the libvirt error into last_error prior to cleanup paths.
However, it caused a regression: on other paths, some errors are now
printed twice, if libvirt still remembers in its thread-local
storage that an error was set even after virsh cleared last_error.
For example:
$ virsh -c test:///default snapshot-delete test blah
error: Domain snapshot not found: no domain snapshot with matching name 'blah'
error: Domain snapshot not found: no domain snapshot with matching name 'blah'
Fix things by telling libvirt to discard any thread-local errors at
the same time virsh prints an error message (whether or not the libvirt
error is the same as what is stored in last_error).
Update the virsh-undefine testsuite (partially reverting portions of
commit b620bdee, by removing -q, to more easily pinpoint which commands
are causing which messages), now that there is only one error message
instead of two.

Rather than have virJSONValueArraySize return a -1 when the input
is not an array and then splat an error message, let's check for
an array before calling and then change the return to be a size_t
instead of ssize_t.
That means using the helper virJSONValueIsArray as well as using a
more generic error message such as "Malformed <something> array".
In some cases we can remove stack variables and when we cannot,
those variables should be size_t not ssize_t. Alter a few references
of if (!value) to be if (value == 0) instead as well.
Some callers can already assume an array is being worked on based
on the previous call, so there's less to do.

Undefined symbols are a bad thing in general because they can get
resolved in unexpected ways at runtime if multiple sources provide the
same symbol name. For example both glibc and libtirpc may provide XDR
symbols and we want to ensure that we resolve to libtirpc if that's what
we originally built against.
The toolchain maintainers thus strongly recommend that all applications
use the '-z defs' linker flag to prevent undefined symbols. This is
shortly becoming part of the default linker flags for RPMs. As an added
benefit this aligns Linux builds with Windows builds, where the linker
has never permitted undefined symbols.

Because WARN_CFLAGS and COVERAGE_CFLAGS are not set globally, we
rely on each binary built to include WARN_CFLAGS/COVERAGE_CFLAGS.
But it is easy to forget those - e.g. libvirt_shell.la. However,
don't enable WARN_FLAGS (i.e. don't include AM_CFLAGS) for
wireshark plugin - parts of that code are generated and trigger
some warnings.

There are couple of limitations when it comes to option types and
flags for the options. For instance, VSH_OT_STRING cannot have
VSH_OFLAG_REQ set (commit c7543a728). For some reason this is
checked in vshCmddefHelp() but not in vshCmddefCheckInternals().

It is literally only a wrapper around virBitmapNewData() and
virBitmapFormat(), only the naming was wrong since it was introduced.
And because we have virBitmap*String functions where the meaning of
the 'String' is constant, this might confuse someone.

Since update to glibc-2.26 removed the /usr/include/rpc/rpc.h we used until now,
it showed us a problem with not using XDR_CFLAGS properly. On linux that
variable has usually -I/usr/include/tirpc because we already probe for it
properly, we just don't use it everywhere we need. It is needed by wireshark
dissector as well as testutilsqemu.c (through includes) so the build fails with:
wireshark/src/packet-libvirt.c:33:10: fatal error: rpc/xdr.h: No such file or directory
#include <rpc/xdr.h>
^~~~~~~~~~~
and
In file included from ../src/logging/log_manager.h:29:0,
from ../src/qemu/qemu_domain.h:40,
from testutilsqemu.c:11:
../src/logging/log_protocol.h:9:10: fatal error: rpc/rpc.h: No such file or directory
#include <rpc/rpc.h>
^~~~~~~~~~~
Since lot of tests use testutilsqemu.c it is easier to add XDR_CFLAGS to
AM_CFLAGS than adding it to all $binary_CFLAGS. It's just for tests and we
already have bunch of CFLAGS there anyway.

The 'set-lifcycle-action' is throwing a weird error after executing it with
the '--help' option. The command output is showing the options 'type' and
'action' are as optional, but they aren't. Both are required.
virsh # set-lifecycle-action --help

SYNOPSIS
set-lifecycle-action <domain> [--type <string>] [--action <string>] ...
...
OPTIONS
[--domain] <string> domain name, id or uuid

After applying this patch, both arguments are required now.

In some cases there's dangling backward slash at the end of multi
line macros. While technically the code works, it will stop if
some empty lines are removed.
Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
Right-aligning backslashes when defining macros or using complex
commands in Makefiles looks cute, but as soon as any changes is
required to the code you end up with either distractingly broken
alignment or unnecessarily big diffs where most of the changes
are just pushing all backslashes a few characters to one side.

Commit fdeac7a05f tried to fix the output
of 'virsh domxml-to-native --help' by switching types around. One of the
changes broke the option parser. VSH_OT_ARGV should be used only for
variable argument count, not to make the help generator look pretty.
The correct option type in this case is VSH_OT_STRING as it's not
mandatory now since it can be substituted by using --domain.
This makes --help for this command look incorrect, but the parser works
as it should.

The command tries to match interface in domain definition by MAC
address or interface name. However, since it's possible to
configure two interfaces with the same MAC address, it may
happen that the XPath returns two or more nodes. We should check
for that.

The current implementation reads the stats from the host.
However, this doesn't work for all types of interfaces as not all
of them have a representation in the host. For instance,

So we refer to the terms 'persistent' and 'transient' across the whole
man page, without describing it further, but more importantly, how the
create command affects it, i.e. explicitly stating that domain created
via the 'create' command are going to be transient or persistent,
depending on whether there is an existing persistent domain with a
matching <name> and <uuid>, in which case it will remain persistent, but
will run using a one-time configuration, otherwise it's going to be
transient and will vanish once destroyed.

In case of PPC, IOMMU in the host kernel either has it or it's not
compiled in. The /sys/kernel/iommu_groups check is good enough to
verify if it was compiled with the kernel or not.
