This properly prints the "Time"/"duration" values for songs in virtual
CUE folders.

`PRIoffset` was wrong, because it expects an `offset_type`
(i.e. `uint64_t`).  This broke on 32 bit machines where `size_t` has
32 bits.

"The documentation for mpd.conf still links to https://replaygain.org
– according to archive.org, this domain has been defunct since
2014-09-14, shortly after got domain squatted and ever since hosts
dubious content."

The `{TAG} {NEEDLE}` input format documented seems to be a holdover
of pre-0.21 filters, and the commands support the new format.

The original base relative path was introduced due to an erroneous test
where the URL started with three slashes: "https:///" instead of two,
which led to implementing handling for such cases but broke the two
slashes case.

This fix removes the base relative path handling because with two
slashes the path is anyway always relative to the host (aka absolute
URI, without host).

There can be more than one propstat block each with their own status
code. We're only interested in the one with the 200 status, the found
properties.

This fixes parsing to make sure we process all propstat blocks instead
of just the last one, which might have a 404 status for not-found
properties.

Some FFmpeg filters change the sample format, and since MPD assumes
this never happens, this results in loud noise instead of music.  This
commit finally implements the TODO comment by sending one frame of
silence to the filter and checking the output frame's format.
