The callback member of dvbpsi_decoder_t is used by dvbpsi_GatherXXSections()
functions. This patch makes the usage visisble.

Update doxygen information and fix linkage of howto-new-api.doxygen

The functions dvbpsi_GatherXSections() and dvbpsi_NewDemuxSubDecoder() take a
private decoder as argument. Change this argument from 'void *' to 'dvbpsi_decoder_t *'.
This makes its use more clear.

Use new utility functions to replace common code blocks. Moving
code to demux.c instead of repeating them in the subtable functions.
This reduces the amount of code in subtable files and reduces the risk
of introducing errors in future for this code.

Refactor common demux code structures into utility functions.
See the complete list below:
- rearrange arguments of dvbpsi_demux_new_cb_t callback
- define dvbpsi_demux_gather_cb_t callback type
- define dvbpsi_demux_detach_cb_t callback type
- new utility function dvbpsi_NewDemuxSubDecoder()
- new utility function dvbpsi_DeleteDemuxSubDecoder()
- new utility funciton dvbpsi_AttachDemuxSubDecoder()
- new utility function dvbpsi_DetachDemuxSubDecoder()

Renaming pf_callback to pf_gather to reflect its usage. It also
removes a typedef which was only used inside src/demux.c

Include config.h as first include file. It comes with some defines needed
for compilation.

Indentation cleanup.

The stdint.h header file was included twice.

- indentation cleanup
- Gather fucnction cleanup
- API cleanup

The compiler warned about comparison of signed and unsigned values. This
patch fixes this comparison.

The descriptor 0x40 was not included in src/Makefile.am. Therefor
syntax errors where not picked up. This patch adds the descriptor
to the src/Makefile.am and fixes a typo.

- refactor descriptor structs allocations

- check for subdec instead of demux when calling dvbpsi_demuxGetSubDec() function
- check if subtable decoder pointer actually exist

- remove excess whitelines
- indent

- remove excess parenthesis
- add boundary checks
- explicite allocation of struct members
  requires explicite release of struct members when freeing
