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

Logging functions nested use of va_arg(), which was wrong. The solutions
is to simplify the logging function nesting.

In monitor mode dvbinfo runs as Unix daemon and the logging goes to syslog instead of stderr.
- added -m (--monitor) commandline switch to run in the background
- added -s (--summary) commandline switch to produce bitrate summary files
- added --summary-file commandline switch to give a summary-file name (default: stdout)
- added --summary-period commandline switch to write every <n> ms a new summary file
- implemented a logging callback function for routing the dvbpsi log messages to dvbinfo application

The code referred to a not defined DVBPSI_MSG_FORMAT define and a not define variable inside the HAVE_VARIADIC_MACROS code block.
