c7b195740e mpegtsparse: actually work when we have small buffers coming in 
available_fast is not what we want and it will never get to discover packet
size if 188 byte buffers are being picked up.

61a8856133 mpegtsparse: don't free PAT structure which may still be needed later 
This is a problem if you tune to a channel which uses pid X and later tune to
another channel where X is used for another table (e.g. PMT).

The code that does that was actually already there but never used because the
pat structure was freed before. The commit that introduced those lines intended
to fix a memory leak, but we clean things up elsewhere.

Fixes #622725.

b1a12c3a2d mpegtsdemux: Don't use liboil functions 
glibc memcpy() will be faster than liboil's/orc's for now anyway
and we can use orc's later, after orc has support for loop unrolling.

e5a37377ae mpegtsdemux: Some checks to avoid asserts 
gst_mpeg_descriptor_find() expects the description field to be non-NULL.
This fixes a couple of calls where the value being passed is not
verified to be non-NULL first.

d2bd939899 mpegtsparse: parse TDT table in mpegts. 
Some tables in MPEG-TS do not have a crc in the spec, so also mpegtsparse
is not calculating crc for sections with table_id 0x70 - 0x72 because they
do not have a CRC in the spec. See EN300468. Parse Time and Date table and
output bus message.

a331228ecc mpegpsdemux: Workaround new gcc 4.5 compiler warning 
gcc 4.5 warns when comparing some integer with an enum value, in
the case of GstFlowReturn this is valid though. We should later
add GST_FLOW_CUSTOM_OK1, GST_FLOW_CUSTOM_OK2, etc. after new core
is released.

d7ab75abb8 mpegtspacketizer: Additionally use the CRC to check if tables are duplicates 
The current code just uses table id, subtable extension and version number to
check if the section has been seen before. However, this comparison is not
sufficient, causing actually new tables being dismissed.

needed) in order to avoid generating an invlaid new-segments event.

This fixes naive seeking a tiny bit (by basically hinting at _data_cb

Without this, seeking by more than 10mins forward would just end up in an
endless loop.
