Try to register profile support again after RegisterProfile fails, when
BlueZ indicates no one else is implementing the profiles we are
interested in.
Ideally this would rely on a list of UUIDs supported by the profile
manager instead of the adapter, but BlueZ has no such API.

Create pa_bluetooth_profile_status_t to represent all stages an external
Bluetooth profile can go through:
0. Inactive: Initial state, no D-Bus object has been registered for
this profile yet.
1. Active: an object implementing the org.bluez.Profile1 interface has
been registered on the system bus.
2. Registering: RegisterProfile has been called.
3. Registered: RegisterProfile succeeded.
This will be useful to handle RegisterProfile failures, as well as
dynamically register and un-register a profile based on the current
active seat.

HF indicator 2 (see [assigned-numbers], Hands-Free Profile) is able to
report battery percentage at 1% intervals (in range [0, 100]), contrary
to the `+XAPL` `+IPHONEACCEV` extension which only supports 10%
increments. This does not guarantee increased granularity however, as
peers may still be limited to imprecise battery measurements internally
or round to coarser percentages.
Supporting both additionally broadens the range of devices for which PA
can report its battery level.

Whenever a device disconnects the device is not removed from BlueZ, only
the profiles that had an active connection are disconnected. Since we
were providing this battery level based on AT commands received through
HSP/HFP these services should be responsible for deregistering it again.
Deregister the interface to signal BlueZ (And UPower in return) that the
battery level won't be accurate/updated anymore.

The peer will wait some time and eventually time out the connection if
no reply is sent back. When sending `ERROR` the peer can decide to break
the RFCOMM connection immediately or continue when a command is not
critical.

Devices for Apple's iOS uses a few extra HFP AT commands to
inform the iPhone about the headphone's battery status.
Apple documented the AT commands in the following document:
https://developer.apple.com/hardwaredrivers/BluetoothDesignGuidelines.pdf
The patch has been tested with a Bose QC35, which results
in the following communication:
D: [pulseaudio] backend-native.c: RFCOMM << AT+VGS=14
D: [pulseaudio] backend-native.c: RFCOMM >> OK
D: [pulseaudio] backend-native.c: RFCOMM << AT+XAPL=009E-400C-0129,3

D: [pulseaudio] backend-native.c: RFCOMM >> OK
D: [pulseaudio] backend-native.c: RFCOMM << AT+IPHONEACCEV=2,1,4,2,0

Alsa UCM device string can contain private configuration prefix required to make
correct device open call. Private prefix is dynamically generated by UCM manager
depending on internal state. Since pulseaudio sink/source port names currently
contain device string, these may change between runs breaking volume database
and module arguments referring to sink/source.
Fix this by skipping UCM private prefix available via `_alibpref` key while
creating UCM mapping name. Mapping object will still contain unmodified
device string for device open call.

When child `gsettings-helper` terminates prematurely, unconditionally reading
from child pipe fails in a busy loop until child process is reaped.
Fix this by terminating module upon PA_IO_EVENT_HANGUP or PA_IO_EVENT_ERROR.

These two log messages are most likely intended for the path that was
just tried, but they are mistakenly printing the name of the port's
current path. Fix them.

Recently we found an issue of output volume on speaker and headphone,
they should have their own volume but in practice they share one
output volume.
This issue happens on the laptops which use the ucm2 sof-hda-dsp,
originally the speaker has output volume A while the headphone has the
output volume B, suppose the speaker is the active port at the moment
and the output volume is A, users plug a headphone to the jack and the
headphone becomes the active port, in this process, ucm_set_port()
calls _disdev/_enadev which triggers the io_mixer_callback(), in the
meanwhile, the module_device_restore will restore the headphone's
volume to B, it will call set_volume_cb() to set the volume to B, but
this value is not written to hw immediately, during the time of
waiting for the B to be written to the hw, the io_mixer_callback()
calls get_volume_cb(), it reads hw volume and gets the volume A, then
it overrides the output volume to A, this results in the headphone
gets the volume A instead of B.
If a machine doesn't use the ucm, this issue will not happen since the
set_port_cb() will not trigger the io_mixer_callback(). If the ports
don't belong to the same sink/source, this issue also doesn't happen.

* Minimal implementation of --system on win32.
* Wrap main with a Windows Service on win32 (with a fallback to
running it directly).
* Update PA_SYSTEM_{RUNTIME,STATE,CONFIG}_PATH and HOME dynamically
on Windows (overrides the build config, similar to the existing
config path replacement logic).

Having G_MESSAGES_DEBUG=all set in the environment (a normal thing to do
when debugging Gnome troubles) causes gsettings-helper to emit a bunch
of helpful gnome debug logs (which is good), but before this change they
were printed on stdout rather than stderr (which was bad!). Rather than
going somewhere the user could see, these log messages were being sent
to the pulesaudio server and interpreted as the src/modules/stdin-util.c
protocol. pulseadio waits to see a '!' message from gsettings-helper
before continuing startup. With the log messages mixed in messing up
the stdin-util protocol, pulseaudio never saw the '!' message, and so
never completed startup.
This simple fix relies on a recent glib > 2.68 (Mar 2021), so builds
against old versions of glib will still have this problem! We consider
this good enough until some complains otherwise.

New card database entry version 5 for card profile is sticky flag.
New messaging API handlers set-profile-sticky and get-profile-sticky.
When card profile is sticky, always restore it even if it is unavailable,
and prevent switching from it when ports become unavailable.
