mpegtspacketizer: Speed up descriptor parsing/packing
...
descriptors are stored as a GValueArray of GString. The downside is
that there is no way to "pass" ownership of a GValue to a GValueArray
which previously resulted in expensive copy/free of the (already expensive)
GString.
Here we estimate first the size of the GValueArray, then create it,
then directly use the GValue of that array.
Speeds up total SI parsing by ~30%

tsdemux: Add support for Motorola DigiCipher II MPEG2 video

Since there is a conflict between the DCII stream type and BluRay
stream types, moved the processing of BluRay-specific stream types
to the beginning of the function. Only if a BluRay stream type
IS NOT found do we proceed to check the rest of the stream type
identifiers
Previous code was also "sort-of" handling a similar conflict between
BluRay AC3 audio and standard AC3 audio. Moved the special case BluRay
AC3 handling in the main switch statement to the new BluRay-specific
switch.

tsdemux: Adapt to new packetizer API
...
We no longer use GstBufferList and instead copy the incoming data
into newly allocated memory.
This makes tsdemux behaviour 3 to 4 times faster.

mpegtspacketizer: Avoid usage of GstBuffer internally
...
The overhead of creating/using 188 byte GstBuffer from GstAdapter
is too expensive.
We now peek the next packet, and provide a data/size which is only
valid until the packetizerpacket is cleared.
In addition, cleanup all the internal code to deal with that new
behaviour and remove double-checks which are no longer needed.
The section_length is now the corrected section_length (i.e. with
the additional 3 bytes).
Avoid using gst_adapter_prev_timestamp and instead track
the timestamp ourself.

tsdemux: flush on pusi only for payload packets
...
Data should not be flushed out of the tsdemux because a payload unit start
indicator (pusi) is seen in a adaptation only ts packet. If the package contains no
payload a pusi does not indicate a new PES packet, but PSI information, etc.
This fixes playback of several TS files which contain ts packets without
payload but with pusi set to 1.
