The shortest valid linkage descriptor contains 56 bits = 7 bytes of payload.
Since the maximum possible payload length is 253 bytes, this leaves 246 bytes
for private data, not 248.

Also, the length checks were changed in order to check the minimum possible
length of the descriptor with the given data, instead of checking maximum
lengths.

GCC 5.1.0 features stricter warnings about comparing boolean variables
with integer values, and thus compilation with --enable-debug failed
with "comparison of constant 12 with boolean expression is always true".
The leftover pieces of old code which treated integers as booleans are
now fixed, and the test suite is now compilable and runs correctly.

The demux API for adding, deleting and selecting subtable decoders is marked
deprecated. It is target for removal for the 2.0.0 release and will be replaced
by a simpler system, that allows each PSI table decoder to be chained without the
need of adding extra structures and indirections.

dvbpsi_GenVStreamDr set the MPEG_1_only_flag incorrectly : it should be
set only if the descriptor does not carry extra information about MPEG-2
video. The previous behaviour was exactly the opposite.

This patch adds support for the MPEG-4 audio descriptor. aac_profile.h is now
allowed to be included multiple times, since it is also used by dr_1c.h.

The definition of AAC profile and level values is also used by the MPEG-4 audio
descriptor. Moving this definition to a separate file eliminates unnecessary
code duplication. New values from the 2015 version of H.222 were also added.
