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

Less duplicate code.

Even when sys/time.h exists the function gettimeofday is not picked up
by this configure script. The example/decode_mpeg.c program compiles
fine when sys/time.h is present.

The cleanup paths forgot to cleanup the libdvbpsi handles.

The cleanup paths forgot to cleanup the allocated libdvbpsi handles.

The assert fired on the p_dvbpsi->p_private being NULL, while it should
have reacted on p_dvbpsi->p_private not being NULL. When the handle to
libdvbpsi (holding msg callback) is being deleted NO decoder maybe attached.

Fixed:
- bug in discontinuity counter signalling (ignore null packets)
- check for TS sync word

The source file had executable permissions which is inappropriate for source code files.

Fix not document functions and wrongly documented functions.

Correct function definitions in doxygen blocks.

All dvbpsi decoders now use dvbpsi_t as handle instead of
dvbpsi_decoder_t *. The pointer to dvbpsi_decoder_t is privatized
and accessible through (dvbpsi_t *)->p_private member. The user
must make sure to cast it to the correct dvbpsi_*_decoder_t type
before accessing structure members.

Dvbpsi decoder developers should use the define DVBPSI_DECODER_COMMON
at the start of a new dvbpsi_*_decoder_t.

WARNING: THIS COMMIT BREAKS THE EXISTING API IN A MAJOR WAY !!!

- most public APIs requires a pointer to existing dvbpsi_t
- new functions to obtain and delete a pointer to dvbpsi_t structure:
  dvbpsi_NewHandle() and dvbpsi_DeleteHandle()
- subtable descriptors fixes
- indentations

The descriptor structs have no reference to dvbpsi_h handle, so using
the dvbpsi_message_cb is currently impossible. Therefor remove the
dvbpsi_error() messages for now.

Follow up of commit id: 1f223e37

Use a message callback of dvbpsi_h instead of printf. The decoder
table functions all use a decoder_t. In dvbpsi.h a decoder_t * is
typedefed as dvbpsi_h.
Table encoder (or generators) do not use a dvbpsi_h handle. The
DVBPSI_{ERROR,DEBUG} have been disabled in these functions for now.

The descriptors will be done in another commit.

Libdvbpsi used printf and fprintf to return debug and error information to the caller.
This bypasses any logging mechanism the calling application uses and does not take
multi-threaded applications into account.
The unifying of messages (error, debug or warning) allows a calling application to
filter (message level: -1, 0, 1 or 2) and handle the messages in its own way.

- add --std=gnu99
- add -D_GNU_SOURCE
- remove DEBUG define in preparation of message callback.

Update documentation information and fix structure somewhat.
