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

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:

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
Using a NULL string for location means that the application
doesn't want the image to be encoded, but wants to receive
the preview image. (Only works for image captures)
Useful for application that want the capture in memory only, like
displaying to the user before it choses to encode or take another
picture in avatar capturing scenarios.

We in fact get the size of the header (including stuffing bytes), therefore
use that instead of trying to skip 0xff bytes ourselves since some media
streams do start with 0xff (like mpeg audio's initial 0xfff).
