Disable flush polling when we don't have data ready to write to the
socket (or socket send failed). This avoids entering into a poll busy
loop, which may result to rtkit killing the process.
Enable SBC-XQ by default, and move it at the end of the codecs list, so
that bluez does not connect to it automatically except when it is the
codec used previously.
When the codec is disabled by quirks, it won't appear in the codecs
list, and so can't be selected by user (and so won't be connected
automatically).
However, since SelectConfiguration does not carry information which
device is in question, we cannot prevent BlueZ connecting to the codec
even if it's disabled for a specific device. If the "impossible" occurs
regardless, we won't reject the connection and the profile will be shown
as the generic "A2DP" one. If the sound is garbled, the user can select
some other profile that works.
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 PW
can report its battery level.

libfreeaptx is a fork of libopenaptx prior to the dubious licensing
situation was introduced to the library.
As it's fully API compatible, let's use that instead for those who
want to use aptX support.
The library source is available at https://github.com/iamthehorker/libfreeaptx
If socket write results to EAGAIN/EWOULDBLOCK or rx data starts late,
spa_bt_sco_io_write may return 0, and we should give up and skip ahead
(and not loop in RT thread with very small timeout).
The kernel-provided SCO write MTU is currently never the correct packet
size for writing, so don't try to use it. Some adapter firmware (eg.
BCM20702A0 0b05:17cb) appears in practice sensitive to the alignment of
the msbc frames, and writes with wrong packet size break things but only
on certain headsets. For other adapters, this doesn't appear to matter.
This is a bitfield, but it's unclear what it achieves since this is the
only member of a bitfield, so it may be more efficient to just make it a
bool.
Fixes a LGTM warning:
Bit field started of type int should have explicitly unsigned integral, explicitly signed integral, or enumeration type.
Mark some structures, arrays static/const at various places.
In some cases this prevents unnecessary initialization
when a function is entered.
All in all, the text segments across all shared
libraries are reduced by about 2 KiB. However,
the total size increases by about 2 KiB as well.
Instead of spa_aprintf(), convert `rfcomm_send_{cmd,query}`
to take a printf-style format string.
Furthermore, handle overflows and return errors from
`rfcomm_send_{cmd,reply}`. And make those functions
take an rfcomm as argument instead of any spa_source.
And match conversion specifiers to the actual types
in format strings.
Several places in the code don't handle reconnecting DBus connections
yet. In those cases, a ref to the DBusConnection handle needs to be
kept, so that there's no use-after-free if it gets freed by spa_dbus
if the connection is broken.
Adjust spa_dbus so that others keeping additional refs is safe.
Use the quirks database to check whether to enable MSBC codec for each
device.
If quirks don't allow ALT1 mode for an USB adapter, check whether the
adapter has an usable ALT6 mode and disable MSBC if not.
It seems few devices support the Device Id via bluez.
Try to figure out vendor/product ids for usb devices also via sysfs.
Also try to figure out the adapter bus type.
Keep all types of devices, only emit device info if device has audio profiles.
Heuristically add profiles based on bluez actions so device can still be connected
even without initial UUIDs info from signal InterfaceAdded for org.bluez.Device1.
Fixes#1330
impl_add_listener() could be called more than one time, ensure that we always emit node info
so that session manager(bluez-monitor) can receives it.
Fixes#1308
bluez5 nodes will always be removed & created again during profile changing, hence
node volume & mute will always be reset. This is OK if profile did changed, because
session manager would carries volume & mute to bluez5 route param. But if profile
was not changed after setting profile (a2dp-sink-sbc -> a2dp-sink -> a2dp-sink-sbc),
session manager would think node volume & mute are not changed and no route
setting is performed, causing route volume out of sync with node volume.
To fix this, we emit node volume and mute right after bluez5 node is created.
Fixes#1254
When we add a new listener to an object, it will emit the full state
of the object. For this it temporarily sets the change_mask to all
changes. Restore the previous state after this or else we might not
emit the right change_mask for the next listener.
Consider the case where one there are two listeners on an object.
The object emits a change and the first listener wants to enumerate the
changed params. For this is adds a new listener and then triggers the
enumeration. If we set the change_mask to 0 after adding the listener,
the second listener would get a 0 change_mask and fail to update
its state.
This replaces the manual check for "true" and some (inconsistent) return value
of atoi. All those instances now require either "true" or "1" to parse as
true, any other value (including NULL) is boolean false.
SPA_MEMBER is misleading, all we're doing here is pointer+offset and a
type-casting the result. Rename to SPA_PTROFF which is more expressive (and
has the same number of characters so we don't need to re-indent).
