This patch adds the PA_COMMAND_SEND_OBJECT_MESSAGE command to protocol-native
so that clients can use the messaging feature introduced in the previous patch.
Sending messages can in effect replace the extension system for modules. The
approach is more flexible than the extension interface because a generic string
format is used to exchange information. Furthermore the messaging system can be
used for any object, not only for modules, and is easier to implement than
extensions.

playing sound through null sink takes almost 2 seconds at first time
playback when norewinds is set. Because block_usec is set 2 seconds at
initializing time. The value will be changed 50 msec after calling
update_request_latency callback.

This replaces the original virtual surround sink with a total
rewrite, aiming to implement any number of hrir use cases,
including asymmetrical impulses as two separate left and right
output files. It uses FFTW3 FFT convolution, using the overlap-
save method, with full rewind support. It operates in steps
equal to the resampled length of the hrir, and overlaps input
blocks in increments equal to the size of the FFT block. If
using paired hrirs, it requires matched sample spec and sample
rates and channel maps. For best results, the input files should
have speaker maps, rather than expecting the sample loader to
auto detect the mapping.

The HP Thunderbolt Dock [1] has two separate USB cards, a headset jack
and an optional module which is a speakerphone.
This patch adds new description for them, and mark the intended-roles as
phone for the speakerphone module.

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.

We already supported the CLFE element, which should be semantically
equivalent, so I just copied all the CLFE element definitions.
The Center/LFE element is seen on Creative X-Fi with 20K1 chipset cards.

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.

Newer GCC warns us that the channel_map and volume in legacy entries are
accessed via pointers, and these might be unaligned as the legacy entry
is a packed structure. For this reason, we read out those values into
local variables before accessing them as pointers.
The warnings are:

Commits 323195e305 ("switch-on-port-available: Switch to headphones on
unknown availability") and d83ad6990e ("module-alsa-card: Drop
availability groups with only one port") broke switching from headphones
to speakers when headphones are unplugged. switch_from_port() selects
speakers, whose availability is unknown and availability group is unset,
and then calls switch_to_port(). The new logic in switch_on_port()
unintentionally blocked that switch.
This patch moves the problematic logic from switch_to_port() to
port_available_hook_callback() where it doesn't interfere with
switch_from_port().

Since not all users will have environments that asks what they plugged
in when their hardware supports TRRS inputs but don't have impedance
sensing, let's emulate our previous default behaviour of enabling the
headphone port at least.
This can likely be improved so users can configure the module to select
for the device they are most likely to plug in (so an option to enable
just the microphone, or headphones+headset-mic ports).

HDMI jacks are configured like this:
[Jack HDMI/DP]
append-pcm-to-name = yes
The pa_alsa_jack.name field is then "HDMI/DP" and pa_alsa_jack.alsa_name
is set to "HDMI/DP,pcm=3 Jack" or similar. If we compare the name fields
of HDMI paths, they appear to use the same jack element even though they
are different in reality, so all HDMI ports got incorrectly assigned to
the same availability group.
Previously they were set once per mapping, which caused the numbering to
restart from 1 for every mapping, so ports were incorrectly assigned to
the same group.
Almost all reports from users, I have seen in last years, were not valid.
The report is also printed when the system scheduler does not wake
the pulseaudio thread in the right time. Users are not able to distinguish
between slow machine and the real problem.
Move the log level from 'error' to 'debug' for those messages.
The right fix should be to measure the time between the call invocation and
return to determine (and skip) the scheduling problems, but it is another
extra code just to debug things.

Packaging shouldn't be using the automatic setting anyway, and let's
disable by default for one release and mark this as experimental so we
can flush out any corner cases.
Since the RTP timestamp is converted to time units and back, a small
error can creep up, which then results in a single frame error in where
we place the buffer in the output memblockq. This results in minor
glitches, so we check for and eliminate the error.
With GStreamer 1.18, the old behaviour of storing the capture time in
DTS is gone (which is reasonable, since the semantics really don't
match). So instead, we get a capture timestamp when the buffer is being
pushed from udpsrc. This should eventually move into udpsrc, and the
timestamp should come from the cmsg instead of the clock.
We still fallback to the DTS if the meta isn't available, as the meta
might be dropped in older versions of rtpL16pay due to a bug.
Hashmap loaded_device_paths contain objects holding keys to entries, and
these objects must be alive while map is emptied.
Reorder freeing this hashmap before destroying device objects to fix
crash on exit.
If port becomes unavailable then PA_CORE_HOOK_PORT_AVAILABLE_CHANGED
callbacks may eventually destroy related source or sink object. Call
this hook after stream is moved to prevent crash reading from freed
memory.
