Calling g_dbus_client_new followed by g_dbus_client_set_proxy_handlers
cause two calls to GetManagedObjects in a row as GetNameOwner reply is
asyncronously it triggers the second call because the handlers have
been set by g_dbus_client_set_proxy_handlers.
In the case that ofono_handsfree_card_connect_sco() is called outside the
context of a .Connect() call, there's no message we need to reply. This
happens, for example, when the HFP AG plugin initiates a SCO connection when
it receives an AT+BCC command from the HF.
When setting the SDP features, only enable wideband speech support if
the kernel has defer setup for SCO.
It is possible that even if defer setup is supported the kernel is
not able to use Transparent Mode for SCO.
It was a cause of confusion for little gain to have separate
functions for registering profiles with extra information, for
example "role" and "features". We remove those helper functions
in favor of a single one with more parameters, "role" and
"feature" when NULL, will be ignored.
This patch extends SetProperty method of the Handsfree interface
allowing to disable echo canceling and noise reduction feature in
the audio gateway through a D-Bus method call. Once disabled, it
is not allowed to enable it using this procedure.
According to Bluetooth HFP spec: By default, if the AG supports its
own embedded echo canceling and/or noise reduction functions, it shall
have them activated until the AT+NREC command is received. The
configuration set by the HF shall by used by the AG while the Service
Level Connection is active.
Since there isn't a command to query the current value, it is being
assumed that Echo Canceling and Noise Reduction is enabled when the
connection is established and the gateway supports this feature.
This patch adds echo canceling and noise reduction property to Handsfree
interface, allowing the handsfree unit to disable this feature in the
audio gateway. The HFP spec defines the procedure to turn off echo
canceling and noise reduction only, it is not allowed to enable this
feature from the HF unit.
According to Bluetooth HFP 1.6 spec: By default, if the AG supports its
own embedded echo canceling and/or noise reduction functions, it shall
have them activated until the AT+NREC command is received from the HF
unit. From then on, and until the current Service Level Connection is
dropped for any reason, the AG shall disable these functions every time
an Audio Connection is established.
A watch to G_IO_HUP is added to remove the file descriptor when the
emulator is automatically disconnected when its GAtServer closes.
We use a dupped file descriptor because the events aren't delivered to
the file descriptor who originated them.
HFP 1.6 adds a new feature called Codec Negotitation. For the HF Role,
this feature is stored in bit 8 of the supported features
bitmap.
This patch changes the range of valid HF feature bitmaps to 2^8-1.
Each time an agent registers itself, we check if we support deferred
setup and if the agent has mSBC as a codec, if both checks are true,
we enable wideband speech support.
'defer_setup' will be one of the inputs when enabling or disabling
support for wideband speech codecs, we will only enable wideband
speech support if the kernel supports deferred setup.
So, we have to have this information available, in this case it means
a global variable.
This patch removes the hard-coded CVSD codec, and adds the selected
codec in the NewConnection method call, notifying the agent the codec
previously selected for the audio connection.
This will be used by the drivers that a given codec was negotiated
for a card.
It will return FALSE if the codec can't be used. For example, if the selected
codec is mSBC and defer setup is not supported by the kernel.
Before, the AT+BAC command was being sent with fixed information,
now we send the command (that inform the AG of the codecs supported by
the HF) with the codecs supported by the registered Handsfree Audio
Agent.
As we can assume that the CVSD codec will be always available, the only
information that we need to export is if we have support for wideband
codecs. Right now only mSBC is defined as wideband.
In case a property did not appear by the time proxy_added was called
property_changed has to be called if it appear latter otherwise the
application will be unaware of it.
g_atomic_* end up using G_STATIC_ASSERT, causing gcc 4.8 to yell due to

This patch parses and reads the profile "Version" that comes in the fd
dictionary of the NewConnection method. "Version" is input for Audio Card
registration.
This can be set by the modem driver to indicate that the device is
always in the online state when it is enabled. This is useful for
modem drivers that handle both CDMA and GSM devices.
