For source file is used the output generated by examples/dvb_gen_si.

The descriptors that have loops in them used their own DESCxx_HEADER_SIZE
defines when calculating descriptor length. That works only in cases when
DESCxx_HEADER_SIZE is equal to DESC_HEADER_SIZE. In order to avoid confusion
and bugs use DESC_HEADER_SIZE instead of redefined value.

For now the file lists programs that are build in examples/ directory.

Better late than never. ;)
