4275a70cb5 mpegdemux: catch section lengths extending past the buffer length 
This is probably the cause for an occasional crash while streaming
MPEG. Blind fix after staring at the code and following logic, so
may or may not fix the issue, I cannot test.

0b4dfa685d mpegtsdemux: fix re-syncing on invalid data after seek 
Or possibly even at startup. If we couldn't find a sync within
the first few bytes, we'd just push more data into the adapter
but never discard any of the invalid data at the beginning, so
would never be able to re-sync.

b11f737096 mpegtsparse: fix handling of TOT and TDT sections. Fixes #635281. 
TDT and TOT sections, with PID=0x14, doesn't extend to several packets
and the section filter is not needed here and shouldn't be used at all
for these tables because the have a different structure.
For example, TDT tables were not parsed for odd hours because this bit
is the 'current_next_indicator' bit for the other sections, and the table
was discarded.

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.

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.

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.

Fixes bug #614479.

ba460f587a mpegdemux: Fix pointer-differences printout 
There is unfortunately no G_*_FORMAT conversion specifier for differences of
pointers in glib, and we can't rely either on all platforms being 64bit.

So let's just cast the difference to a gint and be done with it.

d88af539f9 mpegtspacketizer: Initialize debugging in _get_type 
There's no need for an extra function since all debuggin will require
a MpegTSPacketizer which means that the GType will be created, therefore
move the debug category initialization there.

There's GST_PTR_FORMAT for that, and too bad for the systems that don't have
support for that. It just costs too much cpu.
