The EDID had a few mistakes as reported by edid-decode:
Block 1, CTA-861 Extension Block:
Video Data Block: For improved preferred timing interoperability, set 'Native detailed modes' to 1.
Video Capability Data Block: S_PT is equal to S_IT and S_CE, so should be set to 0 instead.
Fixed those.

Currently the chroma_flags and alpha_flags are being zero'd with a bit-wise
mask and the following statement should be bit-wise or'ing in the new flag
bits but instead is making a direct assignment. Fix this by using the |=

The 'disconnect' error injection functionality suffered from bit rot.
New device nodes were added without updating vivid_user_gen_s_ctrl(), so
that function had to be updated for the new device nodes.
Also, vivid didn't check if specific device nodes were actually ever
created, so the vivid_is_last_user() would fail on that (it would return
true instead of false in that case).
Finally, selecting Disconnect, then unbind the vivid driver would fail
since the remove() would think that the device nodes were already
unregistered. Keep track of whether disconnect was pressed and re-register
the device nodes in remove() before doing the real unregister.

The FWHT stateless 'uAPI' was staging and marked explicitly in the
V4L2 specification that it will change and is unstable.
Note that these control IDs were never exported as a public API,
they were only defined in kernel-local headers (fwht-ctrls.h).
Now, the FWHT stateless controls is ready to be part
of the stable uAPI.
While not too late:
- Rename V4L2_CID_MPEG_VIDEO_FWHT_PARAMS to V4L2_CID_STATELESS_FWHT_PARAMS.
- Move the contents of fwht-ctrls.h to v4l2-controls.h.
- Move the public parts of drivers/media/test-drivers/vicodec/codec-fwht.h
to v4l2-controls.h.
- Add V4L2_CTRL_TYPE_FWHT_PARAMS control initialization and validation.
- Add p_fwht_params to struct v4l2_ext_control.

As defined at ETSI TS 101 162, original network IDs up to 0xfebf
are reserved for registration at dvb.org.
Let's use, instead, an original network ID at the range
0xff00-0xffff, as this is for private temporary usage.
As the same value is also used for the network ID,
the range 0xff01-0xffff also fits better, as values
lower than that depend if the network is used for
satellite, terrestrial, cable of CI.
While here, move the TS ID to the bridge code, where it
is used, and change its value, as it was identical to
the value previously used by network ID. While we could
keep the same value, let's change it, just to make easier
to check for the new code while reading it with DVB tools
like dvbinspector.

The sheet music used to generate the tones had a few
polyphonic notes. Due to that, its conversion to a
tones sequence had a few errors.
Also, due to a bug at the tone generator, it was missing
the pause at the initial compass.
Fix them.
While here, reduce the compass to 100bpm.
The music was converted from a Music XML file using
this small script:
<snip>
my $count = 0;
my $silent = 0;
my $note;
my $octave;
print "\t";
while (<>) {
$note = $1 if (m,\<step\>(.*)\</step\>,);
$octave = "_$1" if (m,\<octave\>(.*)\</octave\>,);
if (m,\<alter\>1\</alter\>,) {
$note .= "S";
$sharp = 1;
}
if (m,\<rest/\>,) {
$note = "SILENT";
$silent = 1;
}
if (m,\<duration\>(.*)\</duration\>,) {
printf "{ NOTE_${note}${octave}, %d},", $1 * 128 / 480;
$count++;
if ($silent || $count >= 3) {
print "\n\t";
$count = 0;
$silent = 0;
