This flag is used to announce that the respective key is mandatory and
therefore the object containing this key is not suitable to be merged
with other objects missing it.

Use defines for the param index.
Fix params for filter. Make it possible to use Props params.

C code doesn't lend itself well to using classes and pages are best for prose.
A doxygen group is a set of related functions - which is exactly what we have
here, e.g. pw_context.

This patch basically adds the following lines to each header:
\defgroup pw_whatever
\addtogroup pw_whatever
\{
....  function declarations ....
\}

Doxygen is smart enough to merge documentation in the header with
documentation in the correspondin .c file where the function is implemented.

Where both declaration and definition are documented, drop one and rely on the
other. Drop the obvious documentations where not needed, doxygen wants either
none or all parameters documented.

These pages never existed, let's not try to reference them.

As of f724319e this happens automatically and
the function is no longer available.

Doxygen complains about invalid HTML tags, let's mark them as code.

When we duplicate the pipeline to match the channels, only check
if a port was used only once for the first instance. Makes
demonic filter work again.

This still referred to a config file format prior to 49d11acd. Reword
sections accordingly and try to explain the actual configuration file format.

xmltoman is quite limited in its supported tags, so we need to use wrong tags
to get some sensible formatting, notably <opt> to get a bold word.

Add a module to set thread priorities without using rtkit.

This replaces the manual check for "true" and some (inconsistent) return value
of atoi. All those instances now require either "true" or "1" to parse as
true, any other value (including NULL) is boolean false.

This change is only done in source files for now, header files will be done
separately.

Easier to use than strcmp() since their return value matches expectations. And
they do what is expected with NULL strings, two NULL pointers are equal, one
NULL pointer is not equal.

strcmp() is easier to get wrong (or lack consistency) so let's abstract all
these calls with a little helper.

udev's ID_MODEL_ID and ID_VENDOR_ID are inconsistent: always 4-digit hex but
sound devices are prefixed with 0x, v4l devices are not. Depending on the
actual ID, the value will look like decimal (1234) or hex (a234).

pw-dump will then print those as either decimal integers (i.e. 0x1234 becomes
decimal 1234) or double (i.e. a234 becomes 41524.00).

Make this consistent by converting the string from hex do decimal where we
get it.

Most of the time when we convert a string to an integer we only care about
success. Let's wrap this with a helper function that sets the value to the
result and returns true on success.

These are not part of the ABI, prefixing them makes this a bit more obvious
that they shouldn't be used.
