For GNOME X11 sessions, avoid relying on xdg autostart desktop files
to initialize the X11 plugins. This is now handled via a systemd unit
file.
The xdg autostart is still installed, but has been made to instruct
GNOME to skip it with X-GNOME-HiddenUnderSystemd. This is still the
primary way to initialize X11 plugins for other DEs.

The scripts in this directory are loaded (in GNOME sessions thus far)
at the time of starting Xwayland for X11 clients (may happen on session
start, or on demand whenever X11 clients are started).
This will ensure the relevant X11 modules are loaded as long as there's
a Xwayland instance, thus X11 clients that might make use of them.

The .include meta command already supports specifying a directory and
when including a directory, all files with the extension '.pa' in that
directory will be parsed in alphabetical order.
This feature can be used to add support for default.pa.d directory, so
that packages for other applications or users can just drop in a file
for configuration without changing the default.pa which is shipped.
We use the PA_DEFAULT_CONFIG_DIR for this, however, since meson quotes
this build variable, introduce an unquoted version for this purpose and
use it with .include.

The webrtc backend of module-echo-cancel uses sscanf() to parse floating
point numbers from module arguments, which didn't work when the locale
used a comma for the decimal point. Setting the LC_NUMERIC locale
variable to C makes the pulseaudio process use a period as the decimal
point regardless of the user's locale configuration.

pa_core_check_idle() uses pa_core.exit_idle_time, which is set after the
pa_core_new() call, so pa_core_check_idle() needs to be called later.
This patch preserves the fact that core state is set to PA_CORE_RUNNING
after checking idle (now in main). It doesn't seem to matter anyway and
main(pa_core_new(state:PA_CORE_STARTUP)->...->state:PA_CORE_RUNNING)
seems right as well.
When running under systemd from its `.service` file, the daemon is
started with `--daemonize=no`. This means that the default logging
target is `stderr` (see the documentation for `--log-target` in
`pulse-daemon.conf(5)`). That works fine, but results in all the
structured logging data from the `pa_log()` calls being thrown away and
not making it into the journal.
In order to preserve structured logging data, and hence make the
messages in the journal a little more useful (for example, allowing the
user to filter by message priority), explicitly pass
`--log-target=journal` in the `.service` file. This should always be
appropriate because the journal should always be used with systemd.

When a source is unlinked, all streams of this source are moved to
default_source, this action is implemented in the core rather than
modules now.
And after this change, the module-rescue-streams is not needed, but
for backward compatibility, we keep it as a dummy module.

remixing-produce-lfe controls upmixing, and remixing-consume-lfe
controls downmixing. The motivation is that a user might want to
synthesize LFE while playing stereo audio on his/her 5.1 speakers,
but at the same time follow the industry recommendation to omit
the LFE channel when producting a stereo downmix (e.g. for headphones)
from 5.1 content. Or the other way round.
Fixes: #753.
Add an xauthority parameter and use it in the startup script.
Apparently on some systems the X authentication cookie is not stored in
~/.Xauthority but in some dynamic location pointed to by the XAUTHORITY
environment variable. The environment variable therefore needs to be set
in the PulseAudio daemon environment in order to have access to the X
server from the PulseAudio daemon, but the variable is not necessarily
set when starting PulseAudio. For example, systemd starts PulseAudio
outside the X session. The start-pulseaudio-x11 script is run in the
X session, so it has the environment variable available, and can pass it
to the X modules, which then can set the variable in the daemon
environment.

Currently, the version check snippet uses a 'bash' extension which
arithemtically evaluates variables prior to expansion. This approach
does not nesseceraly work on other shells which may complain with
'5: Illegal numer' error. Expand the arithmetic expression before
evaluation to avoid such an error.

Almost all distributions patch the configuration to disable
flat-volumes, because users tend to find the concept confusing (and it
also causes nasty surprises when some application pushes the volume to
100%). Let's remove the need for patching and disable the feature by
default.

Removes a warning from HAVE_GCONF not being set, and fixes generation of
a large section that depends on OS_IS_WIN32 being explicitly set to 0.
We can't set OS_IS_WIN32 to 0 by default since a bunch of code uses it
via an ifdef rather than by value.
This was being done automatically by autotools, now we need to manually
specify this for each executable/library with a dependency in a
non-standard directory.
conditions this may lead to massive slowdown of floating point operations
when underflows or denormals are encountered. In particular, this problem
was observed with the soxr resampler after applying
https://gitlab.freedesktop.org/pulseaudio/pulseaudio/merge_requests/120
Therefore this patch adds -ffast-math to the link flags of the pulseaudio
daemon. Linking with -ffast-math adds a procedure set_fast_math() to the
startup code of the daemon. On x86, the procedure sets bit 6 and 15 of the
mxcsr register. When these bits are set, denormals and results of
underflowing operations are truncated to 0.
It is helpful to improve reproducibility build [1] since
PA_SRCDIR/PA_BUILDDIR contains build path,
--disable-running-from-build-tree could drop these macros at
precompilation.

The bool was inverted for some reason - maybe because the next line
prints enable-remixing that needs to be inverted from disable_remixing,
and somehow this logic was accidentally copied to the avoid-resampling
handling.

This is a working implementation of a build with meson. The server,
utils, and most modules build with this, and it is possible to run from
a build tree and play/capture audio on ALSA devices.
There are a number of FIXMEs, of course, and a number of features that
need to be enabled (modules, dependencies, installation, etc.), but this
should provide everything we need to get there relatively quickly.
To use this, install meson (distro package, or mesonbuild.com) and run:
$ cd <pulseaudio src dir>
$ meson <builddir>
$ ninja -C <builddir>
This also makes the module-gconf section conditional on HAVE_GCONF,
because if only gsettings support is built, the gconf section in the
configuration file would be redundant and confusing.
Usually PulseAudio is built with a linker that supports the -z,now
option, and that option should have the same effect (i.e. the dynamic
linker resolves all symbols when the program is started) as re-execing
with the LD_BIND_NOW environment variable set, so usually the re-execing
is redundant.
