This makes updating of permissions on existing directories optional with
pa_make_secure_dir() and pa_make_secure_parent_dir(). This makes sure
that the recursive directory creation doesn't end up modifying existing
directories, and also fixes a problem where creating an auth cookie
(specifically ~/.esd_auth) would end up modifying permissions on ~.
Thanks to Frédéric Danis for reporting this.
Many desktops have headphone on the front and line outs on the back.
Sometimes this means that the headphone is labelled "Front Headphone Jack",
but the volume controls are only "Headphone Playback Volume", i e,
without the "Front" prefix.

Some devices have inverted right channel, so when you add left and right,
the result is silence, or very faint sound. In recent kernels (3.5,
perhaps also 3.4) these are starting to be marked with a special
"Inverted Internal Mic" capture switch.
While we might want to add some reverse summing mechanism in the
future, for now, we just turn the thing off to avoid the problem of
recording silence.

For kernel 3.6, "phantom jack" kctls have been added. They serve as
a marker that a particular port exist. They were made so we can detect
that there actually are speakers and internal mic on a laptop, even if
there are no other indications (volume controls etc).

Several laptops have speaker ports, and/or internal mic ports, but we have
no way of detecting that. So we make the port(s) always show up for these
devices.

In practice there is always at least one profile, and I
don't think there will ever be cards without profiles.
Therefore, I added assertions to pa_card_new() stating that
the card new data must always contain at least one profile.
Now a lot of code can be simplified, because it's guaranteed
that the profiles hashmap and the active_profile field are
always non-NULL.
module-tunnel doesn't care about the proplist contents, so
pa_tagstruct_get_proplist() is only used for removing the
data from the tagstruct buffer. In that case it's more
convenient to just pass NULL as the proplist argument.
PropertyChanged signal of org.BlueZ.MediaTransport is processed in
pa_bluetooth_transport_parse_property() which updates t->nrec.
This is called by :
- First by filter_cb() of bluetooth-util.c
- Then by filter_cb() of module-bluetooth-device.c which retrieve value
of t->nrec before calling parse function, then it checks if t->nrec
has changed before updating bluetooth.nrec property.
As t->nrec has alreday been changed during first process, property
update is never performed.
This patch creates a new hook in pa_bluetooth_transport called
PA_BLUETOOTH_TRANSPORT_HOOK_NREC_CHANGED.
The hook is fired by bluetooth-util.c when the transport's NREC
property changes.
module-bluetooth-device.c won't listen the PropertyChanged signal of
MediaTransport anymore. Instead, it will use the hook in
pa_bluetooth_transport to get a notification when the NREC property
changes, and update the sink or source proplist accordingly.
const qualifier for returned pointer of
pa_bluetooth_discovery_get_transport() is removed.
The bluetooth device should have ports so we can attach a latency to
the ports.
Every profile (a2dp, hsp...) has his own set of ports depending on the
number of sinks and sources it provides.
I doesn't make sense to require all callers of
pa_device_port_new() to create the hashmap themselves. There
are and there will be no cases where a port without any
profiles would be desired.

When a Bluetooth headset is connected only to HFP profile (not connected
to A2DP) and host streams to it, a crash occurs if host disconnects.
When HFP disconnects, audio thread will fail on POLLHUP then generate
a message to set PA profile to Off before ending.
If this message is managed before PA unload bluetooth device module,
all works fine.
But, if this message is managed during module unload, this finish by
re-entrance in release code (stop_thread) and a crash.
This fix prevents to process profile change when module is unloading.
pa_bool_t and dbus_bool_t cannot be used interchangably since their size
might (and do) vary. This caused a crash on some systems which was
reported and root caused by: Aidan Thornton <makosoft@googlemail.com>.

Changes in v2:
- Call the mapping a generic 4-channel input mapping
instead of a 4-channel mic array mapping. The mapping
will be used also by sound cards that have two stereo
input jacks, so in those cases talking about mic arrays
is wrong.
- Added a comment about using the "hw" device name.

Log in as user A, fast user switch to user B, let user B change
port, volume or mute status, then switch back to user A.
At this point we must make sure that the ALSA and PA volumes are
synchronised by writing to the ALSA mixer when the ALSA device
becomes available.

If deferred volumes were activated, set_volume does not really set
the volume, and is probably only meant to be called from the main
thread.
As we're currently really setting the port and the mute here (i e
modifying ALSA), we should really modify the volume as well.

Make sure we can't be called into by remaining references to
sink-inputs and source-outputs after we have unloaded, as
that will likely lead to segfaults.

Coverity thinks that device_name can be NULL when it's
dereferenced by strcmp. Adding an assertion doesn't hurt
here (in my opinion), and that should get rid of the
warning.

Valid channel id range is from 0 to SND_MIXER_SCHN_LAST,
inclusive, so the size of the masks array in pa_alsa_element
has to be SND_MIXER_SCHN_LAST + 1. Similar "too small"
arrays were also in alsa-sink's and alsa-source's userdata,
but actually those arrays were not used at all so they were
removed.
element_is_subset() in alsa-mixer.c skipped the last channel
id when iterating the element masks array; that's now fixed
as well.
Thanks to David Henningsson for spotting the too small
arrays in alsa-sink and alsa-source and the
element_is_subset() problem.
