Comment:
(In [7432]) Fixes #444 and some other memory leaks.
This fixes the all the PES leaks I see on channel changes
with the DVB recorder.
This doesn't use the patch in #444, but fixes that problem
and other problems with PES packet memory allocation and use.
In TVRec and SIScan it adds missing ReturnCachedTable calls.
It adds a DeleteCachedTable() to ATSCStreamData(), and adds
an explicit destructor to ATSCStreamData() that calls Reset().
These changes prevent the leak of 8KB on each channel change.
This also fixes the leak reported in #444, but does this by
handling the special case of a copy from a zero copy PES
packet to a regular PES packet a little more correctly.
This was leaking at least 512 bytes on each channel change.
This also adds a private memory allocation rutine for PES
packets, which takes advantage high number of 188 byte and
4 KB allocations, falling back to malloc when it a packet
is not one of these two sizes.
Finally, this fixes the handling of PES packets larger than
4 KB, before we would punt with a warning when this happened.
With this commit we reallocate if the PES packet grows larger
than the allocated size.
