Add a simple native headset backend that implements support for the
blutooth HSP profile.
This allows pulseaudio to output audio to a Headset using the HSP profile.
Make the native backend the default.
This should not have any effect on behaviour. The goal is to align
with the pattern that I think we should follow:
Object initialization:
- put() is the place to create references from other objects to the
newly created object. In this case, adding the transport to
discovery->transports was moved from new() to put, and adding the
transport to device->transports was moved from set_state() to
put().
Object destruction:
- unlink() undoes put() and removes all references from other objects
to the object being unlinked. In this case setting the
device->transports pointer to NULL was moved from set_state() to
unlink(), and setting the discovery->transports pointer to NULL was
moved from free() to unlink().
- free() undoes new(), but also calls unlink() so that object owners
don't need to remember to call unlink() before free().
Now a2dp and hsp sinks and sources will have different names which means that
applications and other modules can use sink/source to distinguish selected
profile.
Module module-device-restore uses sink/source name and port name as identifier,
so if different profiles have different names module-device-restore can store
volume settings for each profile.
So with this patch it is possible to configure different volume settings for
a2dp and hsp profiles.
This patch does not change port names so gnome applications will be happy.
Note that similar patch is needed also for bluez5, but I'm not using bluez5
so I cannot write or test it.

This allow 'off' profile to be choosen when no other profile is available
which is considered better since it requires less resources than other
profiles.
Register as a HandsfreeAudioAgent with oFono during backend
initialization and unregiter during backend finalization. This commit
also adds a check when receiving method calls or signals to make sure
the sender matches with the D-Bus service we're registered with.
If the transport for the profile doesn't exist, the old behaviour was
to leave cp->available at the default value, which is
PA_AVAILABLE_UNKNOWN, but if there's no transport, the profile should
be marked as unavailable.
This commit adds basic support for devices implementing HSP Headset
Unit, HSP Audio Gateway, HFP Handsfree Unit, HFP Audio Gateway to the
BlueZ 5 bluetooth audio devices driver module (module-bluez5-device).
The code in the "io_fail" section was only used for HUP handling, but
there were jumps to there also from places where reading or writing
failed, because the read/write failure could have been caused by HUP.
This patch simplifies things by checking for HUP condition before
trying to read or write. Now if reading or writing fails, we will
jump to "fail" directly instead of going via the "io_fail" label. As
a result, the "io_fail" label isn't needed any more.
There are several intertwined changes that I couldn't separate into
nicer commits. This is mostly just refactoring, but this also fixes
a bug: the old code set the device valid in parse_device_properties()
even if the device's adapter was invalid (had NULL address).
To improve the clarity of the code, I split the device_info_valid
variable into two booleans: properties_received and valid.
I added function device_update_valid() that checks all conditions that
affect the device validity. The function can then be called from any
place where something changes that potentially affects the device
validity. However, currently the only validity-affecting thing that
can change is the device adapter, so device_update_valid() is only
called from set_device_adapter().
I added the aforementioned set_device_adapter() function so that
whenever the adapter is set, the device validity gets updated
automatically.
The new properties_received variable allowed me to remove the
is_property_update function parameters.
This is a cosmetic change. There are a couple of places where we check
whether the adapter object is valid, and while checking whether the
address property is set works just fine, I find it nicer to have a
dedicated flag for the object validity. This improves maintainability
too, because if there will ever be more adapter properties that affect
the adapter validity, the places that check if the adapter is valid
don't need to be updated.
This name is more acurate with regards of what role we're currently
playing and we've already been using it in
pa_bluetooth_profile_to_string() since 449d6cb.
Currently the latency information is being updated based on the encoded
SBC data instead of the decoded PCM data. Fixing this required moving
the timing update to be after the packet has been decoded.
The Nokia E7 running Symbian Belle Refresh seems to generate invalid SBC
packets every few minutes. This causes pulseaudio to disconnect the
stream and log "SBC decoding error (-3)".
If a single packet is bad, pulseaudio should keep playing the stream.
I think this makes the code a bit nicer to read and write. This also
reduces the chances of off-by-one errors when checking the bounds of
channel count values.
by using pa_modargs_get_sample_rate() we avoid inconsistant validity
checking of the sample rate in various places

When setting attribute foo, or in this case the card profile, in my
opinion the thing passed to the set_foo() function should be of the
type of foo, not a string identifier that can be used to search for
the actual foo in set_foo().
This is mostly a question of taste, but there's at least some small
benefit from passing the actual object: often the profile object is
already available when calling pa_card_set_profile(), so passing the
card name would cause unnecessary searching when pa_card_set_profile()
needs to look up the profile from the hashmap.
When parsing device properties, missing adapter will result in
device_info_valid being set to -1. It is then logical that if the
adapter goes missing at a later point, device_info_valid gets set to
-1 also in that situation.
The function did two things: set device_info_valid to -1 and called
device_free() for each device in the hashmap. Setting
device_info_valid to -1 was unnecessary. The main purpose of that was
to fire DEVICE_CONNECTION_CHANGED as a side effect, but that hook is
fired anyway in device_free(), as a side effect of removing all
transports. Calling device_free() can be delegated to pa_hashmap, when
freeing or emptying it.
