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 IOW, the Author: comments are quickly out of date,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.

The virt-pki-validate tool is extracting components in the x509
certificate Subject field. Unfortunately the regex it is is using is far
too strict, and so truncating valid data. It needs to consider ',' as a
field separator, and if that's not there take all data until the EOL.

With the broken regex:

$ echo "  Subject: O=Test,CN=guestHyp1ver"  | sed 's+.*CN=\(.[a-zA-Z \._-]*\).*+\1+'
guestHyp

And with the fixed regex

$ echo "Subject: O=Test,CN=guestHyp1ver"  | sed 's+.*CN=\([^,]*\).*+\1+'
guestHyp1ver

Since commit v4.3.0-336-gc84726fb all
{hypervisor-,}cpu-{baseline,compare} commands use a generic
vshExtractCPUDefXMLs helper for extracting individual CPU definitions
from the provided input file. The helper wraps the input file in a
<container> element so that several independent elements can be easily
parsed from the file. This works fine except when the file starts with
XML declaration (<?xml version="1.0" ... ?>) because the XML declaration
cannot be put inside any element. In fact it has to be at the very
beginning of the XML document without any preceding white space
characters. We can just simply skip the XML declaration.

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.

This removes code duplication and simplifies cgroup detection.
As a drawback we will not have separate messages to enable cgroup
controller in kernel or to mount it.  On the other side the rewrite
adds support for cgroup v2.

The kernel config support was wrong because it was parsing
'/proc/self/cgroup' instead of '/proc/cgroups/' file.

The mount suggestion is removed as well because it will not work
with cgroup v2.

The domxml-to-native virsh command accepts either --xml or --domain
option followed by a file or domain name respectively. The --domain
option is documented as required, which means an argument with no option
is treated as --xml. Commit v4.3.0-127-gd86531da broke this by making
--domain optional and thus an argument with no option was treated as
--domain.
