(early multi sections table end, segmented EIT failure)

SCTE35 / CUEI Descriptor parsing bug. Descriptor lengths of one byte fail to parse, instead returning null.

The Spec from 2004 to 2016 shows the descriptor payload has never been
more than a single byte.
See SCTE 35 2016 Page 19 Table 2 (Section 8.2).

Correct the length validation check, and reject any descriptor that
IS NOT one byte long, as per the spec.

(cherry picked from commit 37f981c3)

The function dvbpsi_decoder_psi_section_add() never set p_decoder::i_last_section_number when
adding a new section at the end of the list. This was left to the decoder implementations. However
the correct action would have been to set p_decoder::i_last_section_number in dvbpsi_decoder_psi_section_add().

(cherry picked from commit fde118a1)

The EIT tables were output incomplete as the
first sections were always dropped.

(2 sections, last_section == 1)
Ex: section 1
    section 0
    secton  1

IsCompleteEIT is always true in first condition in that case.
It is also always true if section is N/N.
first_section > -1 && section_number == last_section because
it has just been added.

Doing the check before effectively adding the section
allows a correct evaluation against current section.

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.
