Modifiers may have their own PlaybackPCM/CapturePCM and for these, we
create separate sinks/sources. These are marked with the
device.intended_roles property to let role-based routing take care if
streams are tagged appropriately.
The proplist isn't used by the conventional alsa-mixer code path, but
can be used by UCM to transfer properties from UCM data to the
sinks/sources corresponding to a mapping. These properties could be used
later in policy, etc.
The specific use for which I'm writing this now is for UCM modifiers
that have their own PlaybackPCM/CapturePCM field. These will be
translated to a separate sink/source corresponding to the modifier by
adding an additional mapping per sink/source. These mappings' proplist
will be populated with the name of the modifier and corresponding
"device.intended_role" property. The latter will be used in the usual
routing-by-role way, and the former will be used during sink/source
activation and deactivation to know what UCM modifier is to be enabled
or disabled.
Jack in UCM is decided by UCM device name, although in fact
not all UCM devices have "jacks". Because port is also mapped
to UCM device, we can always find target port when some jack
event happens.

UCM basic functions will provide another way to handle the alsa mixer
and controls. That means alsa card module will make use of alsa ucm
configurations provided by various audio systems instead of mixer and
paths configurations provided by PA. PA profiles come from UCM verb, PA
sinks/sources and ports come from UCM devices.
In case the proper UCM configurations are found, ucm branches are
activated, or we will still fall through to the original way.

Some ASUS netbooks, such as the 1015 CX, have only one 3.5 mm jack,
but it can be used either as a headphone or as a mic (but not both
simultaneously).
This patch adds support for the "Headphone Mic" path that is used
on these devices, so that we can use the jack as an external mic, and
doing so without muting the speaker.

Since commit 12af302a last month, cards always have at least one
profile, so there is also always an active_profile (this makes the code
more simple). However, module-coreaudio-device did not create a profile
yet, causing a crash of PulseAudio when used on OS X. This patch fixes
this crash, by adding a single "On" profile. I've also added a TODO for
adding an "Off" profile which removes all sinks and sources -- I can
work on resolving this TODO later on.
As these functions are called together and are related, we might merge
them and call setting_select from pa_alsa_path_select by passing
optional pa_alsa_setting argument.
Make also the setting_select static as it is not called outside of
alsa-mixer.c after this change.
[Additional note from Tanu Kaskinen: this change improves the
mute-during-activation feature, because now the mixer changes related
to selecting the setting happen while the hw is muted.]
Move pa_alsa_setting_select call just after the pa_alsa_path_select in
[sink | source]_set_port_cb functions as there is no dependency to volume
calculations that are done between these two calls. Idea here is to make
possible to merge these two functions since they are called together from
other places too.
It's assumed in a couple of places that entry_read()
initializes entry->profile to a non-NULL string. This patch
makes those assumptions hold.

module-card-restore now saves the latency offsets.
This change includes a entry version bump.
The entry now consists of a port count and a port name and offset for
every port that belongs to the relevant card.
This is a basic module for enabling loopback as soon as a new bluetooth A2DP
source is created. The module is given a source and a media role using command
line. This allows module-intended-roles or module-device-manager to choose a
target sink for the stream.
At module-loopback load, if no sink is given, the default sink is used. If the
stream has a media.role property, the property cannot be used because a the
source or sink is forced to default. Both module-intended-roles and
module-device-manager are affected. The same apply to sources.
With this patch, if sink or source is missing, routing modules can be used.
I forgot half of the front headphone patch, i e, to hide the
speaker output when the front headphone is connected. Thanks to
Shih-Yuan Lee for noticing.

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.

This includes updating the native protocol and the client API.
A new command was added to allow setting the latency offset.
Also the card list command now shows the latency offset if there
are ports available.
Update protocol to 27.
Set the state variable immediately to zero so if we fail to open the
configuration file we don't check an uninitialized pointer and free an
nonexistent proplist.
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.
In my opinion, pa_card_set_profile() should assert that name
is not NULL, and it would be the job of the client interface
to filter out NULLs from the client input, but this is done
this way also when setting sink and source ports, so for
consistency I'll do this this way for now.
I don't like long function parameter lists, and I plan to
add some more state data to the parser which would make the
parameter lists even longer without this refactoring.
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.
