Hi Jon,

That's she second version of the patch series fixing stuff
at media docs with Sphinx 3.1

Patch 1 is identical to the first version. As described before,
it adds support at cdomain.py for two notations found on
Sphinx 3.1:

:c:expr:
.. c:namespace::

The remaining patches remove the cdomain.py dependency from
the userspace-api/media, making them to produce a decent
result with both Sphinx 1.x/2.x and 3.1+.

While at the first version, I did the CEC conversion manually, for
this new version, I wrote a perl script that does the conversion
automatically:

<script>
#!/bin/perl
use strict;

my $namespace = shift or die "need a namespace";
my $file = shift or die "need a file name";

my $header = 1;
my $check_next;
my $changes;

my $out;

open IN, $file;
while (<IN>) {
if ($header) {
if (!m/^\.\.\s+_\S+:/) {
if (m/^\.\./) {
$out .= $_;
next;
}
}
$out .= "\.\. c:namespace:: $namespace\n\n";
$out .= $_;
$header = 0;
next;
}

# Replace :c:func
if (s/:c:func:`(\S+) \<\S+\>`/:c:func:`$1`/g) {
$out .= $_;
$changes = 1;
next;
}
if (s/:ref:`(poll|open|close|select|mmap|munmap|read|write)\s*\s+\<\S+\>`/:c:func:`$1()`/g) {
$out .= $_;
$changes = 1;
next;
}

next if ($check_next && m/^\s+:name:\s+\S+$/);

if (m/\.\. c:function::\s*int\s+(ioctl)\s*$\s*([^$]+),\s*([^\,]+),\s*([^\,]+) \)/
|| m/\.\. c:function::\s*int\s+(ioctl)\s*$\s*([^\,]+),\s*([^\,]+),\s*([^\,]+)$/) {
$check_next = 1;
my $arg0 = $1;
my $arg1 = $2;
my $arg2 = $3;
my $arg3 = $4;

$out .= ".. c:macro:: $arg2\n\n" if ($arg2 =~ m/^[A-Z_]+$/);
$out .= "``int`` :c:expr:`$arg0($arg1, $arg2, $arg3)`\n";
$changes = 1;
next;
}

if (m/\.\. c:function:: int\s+(ioctl)\s*$\s*([^$]+),\s*([^\,]+) \)/
|| m/\.\. c:function:: int\s+(ioctl)\s*$\s*([^\,]+),\s*([^\,]+)$/) {
$check_next = 1;
my $arg0 = $1;
my $arg1 = $2;
my $arg2 = $3;

$out .= ".. c:macro:: $arg2\n\n" if ($arg2 =~ m/^[A-Z_]+$/);
$out .= "``int`` :c:expr:`$arg0($arg1, $arg2)`\n";
$changes = 1;
next;
}

if (m/\.\. c:function:: /) {
$out .= $_;
$changes = 1;
$check_next = 1;
next;
}

$out .= $_;
}
close IN;

$out =~ s/\n\n\n/\n\n/g;

if ($changes) {
open OUT, ">$file";
print OUT $out;
close OUT;
}
</script>

And manually adjusted some issues:
- there were a \*argp on some CEC functions;
- there were some audio C prototypes with bugs. Sphinx 3.2
reported the issue and I manually fixed them.

It should be noticed that the DVB namespace has actually several
sub-namespaces (audio, video, dmx, ca, net and fe), as it contains
different APIs for each type of device.

I'll try to address tomorrow the remaing warnings with Sphinx 3.2.
