Add a clock_ns_to_ticks() function which does the opposite of
clock_ticks_to_ns(): given a duration in nanoseconds, it returns the
number of clock ticks that would happen in that time. This is useful
for devices that have a free running counter register whose value can
be calculated when it is read.

The Clock framework allows users to specify a callback which is
called after the clock's period has been updated. Some users need to
also have a callback which is called before the clock period is
updated.
As the first step in adding support for notifying Clock users on
pre-update events, add an argument to the ClockCallback to specify
what event is being notified, and add an argument to the various
functions for registering a callback to specify which events are
of interest to that callback.
Note that the documentation update renders correct the previously
incorrect claim in 'Adding a new clock' that callbacks "will be
explained in a following section".

This is a plugin intended to help with profiling access to various
bits of system hardware. It only really makes sense for system
emulation.
It takes advantage of the recently exposed helper API that allows us
to see the device name (memory region name) associated with a device.
You can specify arg=read or arg=write to limit the tracking to just
reads or writes (by default it does both).
The pattern option:
-plugin ./tests/plugin/libhwprofile.so,arg=pattern
will allow you to see the access pattern to devices, eg:
gic_cpu @ 0xffffffc010040000
off:00000000, 8, 1, 8, 1
off:00000000, 4, 1, 4, 1
off:00000000, 2, 1, 2, 1
off:00000000, 1, 1, 1, 1
The source option:
-plugin ./tests/plugin/libhwprofile.so,arg=source
will track the virtual source address of the instruction making the
access:
pl011 @ 0xffffffc010031000
pc:ffffffc0104c785c, 1, 4, 0, 0
pc:ffffffc0104c7898, 1, 4, 0, 0
pc:ffffffc010512bcc, 2, 1867, 0, 0
You cannot mix source and pattern.
Finally the match option allow you to limit the tracking to just the
devices you care about.

Meson's "static" argument to cc.find_library is a tri-state. By default
Meson *prefers* a shared library, which basically means using -l to
look for it; instead, "static: false" *requires* a shared library. Of
course, "static: true" requires a static library, which is all good
for --enable-static builds.
For --disable-static, "static: false" is rarely desirable; it does not
match what the configure script used to do and the test is more complex
(and harder to debug if it fails, which was reported by Peter Lieven
for librbd).

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.

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 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.

The tracetool.py script writes to stdout. This means the output filename
is not available to the script. Add the output filename to the
command-line so that the script has access to the filename.
This also simplifies the tracetool.py invocation. It's no longer
necessary to use meson's custom_build(capture : true) to save output.

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).
