5b1191cb4c dvbsrc: smarten-up delsys autodetection logic 
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.

c7e0e8d6ab dshowsrcwrapper: fix DirectShow caps negotiation and set capture pin caps 
Some cameras (IDS) have broken DirectShow drivers which incorrectly fill some
fields in the VIDEOINFOHEADER structure; comparison between suggested and
supported media types in CBaseRenderer should ignore deprecated and/or not
essential fields; additionaly explicitely setting the mediatype for the capture
pin before trying to connect it works around another IDS driver bug, and
should have been already done anyway.

c257829213 ahc: eliminate AHC*_CALL macros 
Currently, we use AHC*_CALL macros to call many of the Camera functions.
However, we already have helper classes to call the Camera functions, so
eliminate the macros.

As a nice side-benefit, we also get improved error handling and
reporting when something goes wrong calling these functions, because a
GError gets populated, and we log a GST_ERROR when something fails. This
was harder to do using macros, as all error handling was hidden from the
caller.

Currently it was wrongly reporting min/max as being the shortest and
longest possible frame duration. This is not how latency works in

Fix by reporting min latency as being the longest possible duration of
one frame. As we don't know how many buffers the stack can accumulate, we
simply assume that max latency is the same (the usual default behaviour).

691ab727b0 androicamera: if buffer size increases, then readd new buffers to the queue and drop old ones 
The on_preview callback gets called with NULL if the buffer in the queue is
too small, so we need to handle the case where the array is NULL. Also
there is a bug in the android source which makes it drop one of the buffers
so if we had 5 buffers, and we renegotiate to a higher resolution, then we'd
only get 4 calls to on_preview_frame with NULL, with one being dropped.
This means we can't reallocate the buffers in the if (data == NULL) case
because we might end up with 0 buffers in the end.

936b2fdfbc applemedia: implement GstAppleCoreVideoMemory 
Implement a new memory type wrapping CVPixelBuffer.

There are two immediate advantages:
 a) Make the GstMemory itself retain the CVPixelBuffer. Previously,
    the containing GstBuffer was solely responsible for the lifetime of
    the backing CVPixelBuffer.

    With this change, we remove the GST_MEMORY_FLAG_NO_SHARE so that
    GstMemory objects be referenced by multiple GstBuffers (doing away
    with the need to copy.)

  b) Delay locking CVPixelBuffer into CPU memory until it's actually
     mapped -- possibly never.

The CVPixelBuffer object is shared among references, shares and
(in planar formats) planes, so a wrapper GstAppleCoreVideoPixelBuffer
structure was introduced to manage locking.
