FSF addresses used in PA sources are no longer valid and rpmlint
generates numerous warnings during packaging because of this.
This patch changes all FSF addresses to FSF web page according to

Done automatically by sed-ing through sources.
These two control names are currently being added to the HDA driver,
so let's support them in PulseAudio as well.

Recognize the Dock headphone jack in the same way the normal & front
headphone jacks are detected.

In the (theoretical) case that no other elements exists but
"Line HP Swap", the presence of that element signals that there are
headphone and line-out outputs, otherwise there would be nothing to
swap.
These kcontrol names have started to show up lately, in
combination with surround internal speakers.

Previously the path description was looked up based on the
path name only. Since there can be multiple paths that use
the same description, it had to be possible to have multiple
paths with the same name.
Having the same name with multiple paths makes identifying
the paths more complex than necessary, so the plan is to
make it impossible to have paths with the same name. This
patch prepares for that by retaining the possibility to
still have the same description with multiple paths. Instead
of the path name, the path description is looked up by using
the "path description key" if it is set (path name is still
used as a fallback lookup key).
When a "Headphone Mic" jack becomes available, we do not know if
a headphone or a mic has been plugged in. Therefore, setting both
paths to "unknown" is, in theory, the correct thing to do.
However, in practice, people are more likely to plug in a headphone
rather than a mic. Therefore, allow autoswitch to the headphone port
when the jack is plugged in.
A more advanced implementation would consider what was plugged in last
time depending on what port was selected on the input side at that
time, and set availability accordingly. However, such an implementation
will have to wait (probably at least until we have our fancy routing
system implementation).

Found on Logitech B530 USB Headset / kernel 3.8. Because we don't
have different path for headset and headphone today, just add
Headset to the existing headphone path.

It's fairly uncommon, but it happens that jack detection is enabled
for some reason, e g hardware design. In that case, we cannot use
jack detection, but we can still use the hint to pick up that there
is a path.

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.

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.

Support the new jack detection interface implemented in Linux 3.3
(and Ubuntu's 3.2 kernel).
Jacks are probed and detected using the snd_hctl_* commands, which
means we need to listen to them using fdlists. As this detection
needs to be active even if there is currently no sink for the jack,
so this polling is done on the card level.
Also add configuration support in paths, like this:
[Jack Headphone]
required-any = any
...where 'Jack Headphone' should match 'Headphone Jack' as given by
ALSA (as seen in e g 'amixer controls').
"Required", "required-any" and "required-absent" is supported. Using
required-any, one can have several ports even though there is no
other indication in the mixer that this path exists.

I've seen more than one system where the volume control named
"Front" is a part of audio path for headphones. This is somewhat
of a compromise: While we don't merge it into the path, as that
would be regressing machines where "Front" isn't a part of the
audio path, it would still enable sound on these machines.

Completely rework mixer logic. This now allows controlling a full set of
elements from a single sink's volume slider/mute button.
This also introduces sink and source "ports" that can be used to choose
different input or output ports with the UI. (i.e. "mic"/"line-in" or
"speaker"/"headphones".
The mixer paths and device maps are now configered in external
configuration files and can be tweaked as necessary.
