When there's no explicit delivery system information
for a channel in the channel configuration file and
the user hasn't selected one via setting the delsys
property, we *guessed* it by selecting the last
supported delsys reported by the driver. This change
provides the basis for smarter delsys auto detection
and implements a rule for DVB-T2. Rules for other
delivery systems can be added in _guess_delsys() in
a similar way.
Additionally: Store list of adapter-supported
delivery systems instead of querying the driver each
time this information is needed.

It works the same as the 'tune' property that is used only to signal
the element that it should tune, but it is more natural to be used
as a signal rather than a property.
It is also proxied at the dvbbasebin element
ISDB-T and ISDB-Tb (the Brazilian variant) are the
terrestial DTV standards used by Japan, Philippines,
Maldives, Thailand, most South American countries
and Botswana. Changeset adds the set of previously
missing (and required) ISDB-T parameters, adapter
and frontend setup logic and proxies the new
properties on dvbbasebin.
Tested to work with the live aerial broadcast by
Tv Paraíba HD in Campina Grande (Brazil).

Allows proper tuning around high/low band boundaries when using
non "standard" LNBs.
Not all LNBs (Low noise block down converters) are made equal.
This is particularly true for universal LNBFs, where, even though
there are seemingly standard values for the local oscillator
frequencies, these can vary from manufacturer to manufacturer
and LNB model. Change also proxies the new LNB properties in
dvbbasebin.

* Drop remaining sleep() logic in favor of polling
* Use best guess delivery system if none is set
* Make tuning/locking timeout configurable
* Add signals for tuning start, done and fail
* Drop gst_dvbsrc_frontend_status(). It was used only
for signal LOCK checking. This is now part of the
tuning/locking loop
* Break up frontend configuration and tuning
on separate functions
Plus:
* Add some more useful DEBUG/TRACE messages
* Move over misplaced DVB API message
* Fix wrong comment for default DVB buffer size (http://linuxtv.org/downloads/v4l-dvb-apis/dmx_fcalls.html#DMX_SET_BUFFER_SIZE)

-add delsys property
-add delivery system capability to the gstreamer adapter structure
-ready for add new delivery systems
Application must ask the adapter structure to know which delivery systems are avaible.
The property delsys must be set.

This allows to use much higher timeout values because GstPoll
is interruptible and keeps the number of wakeups during signal
loss lower.
Fixes bug #608171.

Integrate SoC work done by Alessandro for the Freevo project.
Adds cam support to the dvb stack in GStreamer and a new
element (actually a bin) called dvbbasebin that integrates
dvbsrc and mpegtsparse to a) handle decryption and b) allow
acquiring multiple channels on same transponder without
knowing pid numbers.

adapter-prefix is a terrible name for a device, so replace it.
strerror should be used immediately after the syscall related to it.
Actually throw a reasonable GST_ELEMENT_ERROR if we fail to open
(pretty easy to trigger by opening the same device twice).
Use _OBJECT macros where it makes sense.
This element is going to need some work before it moves.
