GstPhotography API contains functions to get/set flicker reduction
mode, but GstPhotoCaps enumeration doesn't have item for it, so elements
are not able to report whether they support this feature or not.
Also add useful GST_PHOTOGRAPHY_CAPS_ALL for easily selecting all
capabilities at once.

Property "quality" to specify VBR quantizer quality and property
"brtype" to choose between ABR and VBR encoding. The default is now VBR
with quality=100.
Fixes bug #654310.

camrabin2 connects a viewfinderbin on "vfsrc". viewfinderbin is made of:
vfbin-csp ! vfbin-videoscale ! videosink.
we should either remove csp/videoscale from wrappercamerabinsrc (as
done in this patch) or we should get rid of viewfinderbin altogether.
The use of this method was removed in:
commit 539f10f4d9
basecamerasrc: More cleanup
The code from wrappercamerabinsrc is from v4l2camerasrc but is unused:
get_allowed_input_caps is not called anywhere.
The audio source inside camerabin2 is put to READY and back to
PLAYING when starting capture, causing the pipeline to lose its
clock. As camerabin2 isn't put to PAUSED->PLAYING again during
this, a new clock isn't selected for elements.
A flags property has been added to encodebin to toggle whether the
conversion elements (ffmpegcolorspace, videoscale, audioconvert,
audioresample, audiorate) are created and linked into the appropriate
branches of encodebin.
Not including these elements avoids some slow caps negotiation and
allows the first buffers to flow through encodebin much more quickly.
However, it imposes that the uncompressed input is appropriate for the
target profile and elements selected to meet that profile.
If we bring the audio source up to the PAUSED state before emitting the
start-capture signal to the camera source, when subequently taking the
audio source to the PLAYING state, it will begin capture more quickly.
Since camerabin2 has switched to encodebin and encodebin has its own
queues and conversion elements, those preceding encodebin are no longer
necessary and as such can be removed.
Previously hlsdemux wasn't sending out any newsegment.
Here we push a GST_FORMAT_TIME newsegment, and whenever possible we
try to indicate the proper start time.
This allows downstream elements to relay the start/time values properly
to the sinks, allowing better stream switching.
The program_stopped vmethod was called before stream_removed vmethod
was being called. Since we only did stream-related operations in there,
we just remove the program_stopped vmethod and do everything in the
stream_removed one.
Also, make sure we flush out all pending data before sending EOS.
stream_type is stored as guint inside the GstStructure but was retreived
using valist with a pointer to guint16. This would cause stack gardening
when code is compiled without optimisation (e.g. in -O0 the compiler wont
pad the stack to optimise out required mask).

When switching bitrates, we might end up switching to a different
media-type (like from aac to/from mpeg-ts).
For this switch to behave properly in decodebin2, this patch adds:
* dynamic source pads (which will be added/removed whenever a stream
media type changes
* re-checking the fragment media type whenever we switch to a different
playlist
gstpcapparse.c: In function 'gst_pcap_parse_chain':

The current code is not checking for ethernet type, as it's supposed to,
but link layer device type and it's hard-coded to only accept dumps from
ethernet (ARPHRD_ETHER; 1). We don't care where the dump was fetched
from (wlan, 3G, etc.)
What we care about is the that the ethernet type is IP (ETHERNET_IP;
0x800), which is clearly field 14:
http://www.tcpdump.org/pcap3_man.html
And do a bit of cleanup.

We first activate new streams before shutting down old ones.
We emit no-more-pads after we add new streams and emit EOS before
removing old ones.
Also cleanup/refactor a bit more of the code accordingly
