v4l-utils: run sync-with-kernel, add ioctl32 tests for v4l2-subdev.h

The v4l2-subdev ioctls were never tested in compat32 mode. Add the v4l2-subdev.h
header to v4l-utils when running sync-with-kernel and fix the gen_ioctl_list.pl
script to generate the subdev ioctls.

libdvbv5: fix reading multisection tables

Unfortunately the section ids are not granted to be incremented by one.
This means the last section id is not necessarily equal to the total
number of sections. The only way to know if everything has been parsed, is
to stop when a repeating section id has been found.

The sections do not need to contain the same table id. In EIT for example,
the id designates the corresponding service.
Thus, allow the table id to differ.
