d152c727c6 snapshots: Avoid term 'checkpoint' for full system snapshot
Upcoming patches plan to introduce virDomainCheckpointPtr as a new
object for use in incremental backups, along with documentation on
how incremental backups differ from snapshots.  But first, we need
to rename any existing mention of a 'system checkpoint' to instead
be a 'full system snapshot', so that we aren't overloading
the term checkpoint.

5817dec014 virsh: Elide backslash-newline in batch mode
The previous patch made it possible to split multiple commands by
adding newline, but not to split a long single command. The sequence
backslash-newline was being used as if it were a quoted newline
character, rather than completely elided the way the shell does.

Again, add more tests, although this time it seems more like I am
suffering from a leaning-toothpick syndrome with all the \.

fe1b683fd0 virsh: Treat \n like ; in batch mode
I wanted to do a demonstration with virsh batch mode, which
takes multiple commands all packed into a single argument:

$ virsh -c test:///default 'echo a; echo b;'
a
b

but that produced a really long line, so I tried to make it
more legible:

$ virsh -c test:///default '
   echo a;
   echo b;
'
error: unknown command: '
'

Let's be more like the shell, and treat unquoted newline as a
command separator just as we do for semicolon.  In fact, with
that, I can even now mix styles:

$ virsh -c test:///default '
   echo a; echo b
   echo c
'
a
b
c

a87a75e579 tools: Keep wireshark plugin registration code in git
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.

6a4d938dd3 Require a semicolon for VIR_ENUM_IMPL calls
Missing semicolon at the end of macros can confuse some analyzers

non-semicolon usage through the code. Let's standardize on using

Move the verify() statement to the end of the macro and drop
the semicolon, so the compiler will require callers to add a
semicolon.

While we are touching these call sites, standardize on putting
the closing parenth on its own line, as discussed here:

600462834f Remove all Author(s): lines from source file headers
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.

11ceedcda0 tools: Add virsh iothreadset command
Add a command to allow for setting various dynamic IOThread polling
interval scope (poll-max-ns, poll-grow, and poll-shrink). Describe
the values in the virsh.pod in as generic terms as possible. The
more specific QEMU algorithm has been divulged in the previous patch.

Based heavily on code originally posted by Pavel Hrdina
<phrdina@redhat.com>, but altered to only provide one command
and to not managed a poll disabled state.

66a85cb136 libvirt: add daemon itself as shutdown reason
This patch introduces a new shutdown reason "daemon" in order
to indicate that the daemon needed to force shutdown the domain
as the best course of action to take at the moment.

This action would occur during reconnection when processing
encounters an error once the monitor reconnection is successful.

35966308b5 virsh: Fix regression with duplicated error messages
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

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-gd86531daf2 broke this by making
--domain optional and thus an argument with no option was treated as
