Add support for hfgw card profile in module-bluetooth-policy, just like
a2dp_source is handled.
In this case also the sink needs to be connected using module-loopback.
Instead of focusing on a2dp_source only, prepare the module to support
several profiles. It will be possible to enable/disable each of them
using module arguments.
Property bluetooth.protocol did make a distinction between A2DP sink and
source roles but on the contrary did not separate HFP roles (headset vs
gateway). For consistency, they should both behave similarly.
This automatically fixes another incosistency: the HFGW (or HSP) sink
was set to bluetooth.protocol="sco", while the source was set to "hsp".
There is no use for this distinction, since the protocol (including the
role) is the same.
On ARM, pa_object has less strict alignment requirements
than e.g. pa_sink and pa_source, so when pa_object is cast
to pa_sink, the compiler thinks that it's unsafe. In this
case, however, the pointer given to pa_sink_ref() was a
pa_sink pointer to begin with, so casting it first to
pa_object and then back to pa_sink is entirely safe.
This particular source of warnings is extremely annoying,
because this message is printed for any compilation unit
that includes sink.h, source.h or any other header that
defines a class, and the message tends to get printed
multiple times for one compilation unit:

Profile a2dp_source, just like any other card profile, should have
state guards when the profile is being changed. If the BlueZ interface
is not connected, the profile should be set to "off".
Fixes this:
/usr/bin/ld: utf8_test-utf8-test.o: undefined reference to symbol 'pa_log_set_level'
/usr/bin/ld: note: 'pa_log_set_level' is defined in DSO /home/takaskin/dev/pulseaudio/src/.libs/libpulsecommon-2.98.so so try adding it to the linker command line
/home/takaskin/dev/pulseaudio/src/.libs/libpulsecommon-2.98.so: could not read symbols: Invalid operation
With this fix, `check-daemon` doesn't need a system-wide running pulseaudio
anymore.
The method to use is to invoke `make check-daemon` under `src/` and it just
works! :)
