Some distros (Ubuntu lucid) have slightly different glibc headers and require sys/types.h to be
included explicitly.

This struct was defined in two descriptors.

Found better solution.

This reverts commit 3b68bd17.

Make sure these definitions do not interact with each other.

When p->i_number == p_section->i_number AND p_prev == NULL, then the function
will crash with a segmentation fault. In this case the first element in the linked
list is going to be replaced. The pointer p_prev does not point to a valid sections,
since p is the first element in the list. To solve this case it needs to be treated
seperate.

Various fixes:
- add boundary check for p_decoded->i_references
- fix comments

Duplicating p_descriptor->p_decoded which has just been newly create is
wrong. The pointer is empty. What should have been done is duplicating
the pointer p_decoded which is passed to the generator function for the
descriptor.

Decode AAC Audio descriptor 0x7c and identify profile, level and type.
