Add python script with new logic of searching for tests:
Current ./check behavior:
- tests are named [0-9][0-9][0-9]
- tests must be registered in group file (even if test doesn't belong
to any group, like 142)
Behavior of findtests.py:
- group file is dropped
- tests are all files in tests/ subdirectory (except for .out files),
so it's not needed more to "register the test", just create it with
appropriate name in tests/ subdirectory. Old names like
[0-9][0-9][0-9] (in root iotests directory) are supported too, but
not recommended for new tests
- groups are parsed from '# group: ' line inside test files
- optional file group.local may be used to define some additional
groups for downstreams
- 'disabled' group is used to temporary disable tests. So instead of
commenting tests in old 'group' file you now can add them to
disabled group with help of 'group.local' file
- selecting test ranges like 5-15 are not supported more
(to support restarting failed ./check command from the middle of the
process, new argument is added: --start-from)
Benefits:
- no rebase conflicts in group file on patch porting from branch to
branch
- no conflicts in upstream, when different series want to occupy same
test number
- meaningful names for test files
For example, with digital number, when some person wants to add some
test about block-stream, he most probably will just create a new
test. But if there would be test-block-stream test already, he will
at first look at it and may be just add a test-case into it.
And anyway meaningful names are better.
This commit doesn't update check behavior (which will be done in
further commit), still, the documentation changed like new behavior is
already here. Let's live with this small inconsistency for the
following few commits, until final change.

Options such as "server" or "nowait", that are commonly found in -chardev,
are sugar for "server=on" and "wait=off". This is quite surprising and
also does not have any notion of typing attached. It is even possible to
do "-device e1000,noid" and get a device with "id=off".
Deprecate it and print a warning when it is encountered. In general,
this short form for boolean options only seems to be in wide use for
-chardev and -spice.

The HMP command \"change vnc TARGET\" is messy:
- it takes an ugly shortcut to determine if the option has an "id",
with incorrect results if "id=" is not preceded by an unescaped
comma.
- it deletes the existing QemuOpts and does not try to rollback
if the parsing fails (which is not causing problems, but only due to
how VNC options are parsed)
- because it uses the same parsing function as "-vnc", it forces
the latter to not support "-vnc help".
On top of this, it uses a deprecated QMP command, thus getting in
the way of removing the QMP command. Since the usecase for the
command is not clear, just remove it and send "change vnc password"
directly to the QMP "change-vnc-password" command.

When we first converted our documentation to Sphinx, we split it into
multiple manuals (system, interop, tools, etc), which are all built
separately. The primary driver for this was wanting to be able to
avoid shipping the 'devel' manual to end-users. However, this is
working against the grain of the way Sphinx wants to be used and
causes some annoyances:
* Cross-references between documents become much harder or
possibly impossible
* There is no single index to the whole documentation
* Within one manual there's no links or table-of-contents info
that lets you easily navigate to the others
* The devel manual doesn't get published on the QEMU website
(it would be nice to able to refer to it there)
Merely hiding our developer documentation from end users seems like
it's not enough benefit for these costs. Combine all the
documentation into a single manual (the same way that the readthedocs
site builds it) and install the whole thing. The previous manual
divisions remain as the new top level sections in the manual.
* The per-manual conf.py files are no longer needed
* The man_pages[] specifications previously in each per-manual
conf.py move to the top level conf.py
* docs/meson.build logic is simplified as we now only need to run
Sphinx once for the HTML and then once for the manpages5B
* The old index.html.in that produced the top-level page with
links to each manual is no longer needed
Unfortunately this means that we now have to build the HTML
documentation into docs/manual in the build tree rather than directly
into docs/; otherwise it is too awkward to ensure we install only the
built manual and not also the dependency info, stamp file, etc. The
manual still ends up in the same place in the final installed
directory, but anybody who was consulting documentation from within
the build tree will have to adjust where they're looking.

The PWM module is part of NPCM7XX module. Each NPCM7XX module has two
identical PWM modules. Each module contains 4 PWM entries. Each PWM has
two outputs: frequency and duty_cycle. Both are computed using inputs
from software side.
This module does not model detail pulse signals since it is expensive.
It also does not model interrupts and watchdogs that are dependant on
the detail models. The interfaces for these are left in the module so
that anyone in need for these functionalities can implement on their
own.
The user can read the duty cycle and frequency using qom-get command.

The clock_get_ns() API claims to return the period of a clock in
nanoseconds. Unfortunately since it returns an integer and a
clock's period is represented in units of 2^-32 nanoseconds,
the result is often an approximation, and calculating a clock
expiry deadline by multiplying clock_get_ns() by a number-of-ticks
is unacceptably inaccurate.
Introduce a new API clock_ticks_to_ns() which returns the number
of nanoseconds it takes the clock to make a given number of ticks.
This function can do the complete calculation internally and
will thus give a more accurate result.

Anywhere we create a list of just one item or by prepending items
(typically because order doesn't matter), we can use
QAPI_LIST_PREPEND(). But places where we must keep the list in order
by appending remain open-coded until later patches.
Note that as a side effect, this also performs a cleanup of two minor
issues in qga/commands-posix.c: the old code was performing
new = g_malloc0(sizeof(*ret));
which 1) is confusing because you have to verify whether 'new' and
'ret' are variables with the same type, and 2) would conflict with C++
compilation (not an actual problem for this file, but makes
copy-and-paste harder).

When kernel-doc is called via kerneldoc.py, there's no need to
auto-detect the Sphinx version, as the Sphinx module already
knows it. So, add an optional parameter to allow changing the
Sphinx dialect.
As kernel-doc can also be manually called, keep the auto-detection
logic if the parameter was not specified. On such case, emit
a warning if sphinx-build can't be found at PATH.
I ended using a suggestion from Joe for using a more readable
regex, instead of using a complex one with a hidden group like:
m/^(\d+)\.(\d+)(?:\.?(\d+)?)/
in order to get the optional <patch> argument.

Preserve bisectability while we update scripts/kernel-doc from Linux.
Without this patch, building with Sphinx 3 would break while we
revert our own Sphinx 3 support and replace it with Linux's.

Adds bit #4 to status/control field of CPU hotplug MMIO interface.
New bit will be used OSPM to mark CPUs as pending for removal by firmware,
when it calls _EJ0 method on CPU device node. Later on, when firmware
sees this bit set, it will perform CPU eject which will clear bit #4
as well.
