Descriptors generators and decoders return NULL on error and a pointer to
the descriptor structure on success.

Remove b_append from dvbpsi_GatherCATSections()

- remove b_append from dvbpsi_GatherTOTSections()

Type int was used with some variables prefixed with b_ treating them
as booleans. This patch turns them into real booleans.

No functional changes.

Use dvbpsi_NewDecoder() and dvbpsi_DeleteDecoder() to allocate decoders for Demux, PAT, PMT and CAT.

Assert if p_decoder->p_current_section is not NULL.

Do not make an exception for dvbpsi tables debugging.

Change prototype of dvbpsi_PushPacket() to return bool iso void

Do not check continuity counter when this PID has not been seen before.
This used to produce false positives.

SCTE 35 2004 section 7.2 describes the following Splice Commands:
- 0x00 splice_null
- 0x04 splice_schedule
- 0x05 splice_insert
- 0x06 time_signal
- 0x07 bandwidth_reservation

Make use p_current->b_syntax_indicator and p_current->b_private_indicator are used as booleans.

The dvbpsi_decoder_t members b_discontinuity and b_complete_header are used as a boolean.

Simplify code by using dvbpsi_HasDecoder().

The function dvbpsi_HasDecoder(dvbpsi_t *handle) returns 'true' when a decoder has been attached to this dvbpsi handle. If the handle is not valid or no decoder is attached, then it will return 'false'.

The dvbpsi-info tool provides information about the DVB PSI tables in
DVB and MPEG-TS streams (or files). It uses libdvbpsi to gather all
information and prints it to stdout.

Remove executable bit.

Check mallocs return value.

- Add pointer to dvbpsi_t * to dvbpsi_BuildPSISection()
- Make dvbpsi_ValidTOTSection() return a boolean
- Make dvbpsi_ValidPSISection() return a boolean
