Fix the possibly wrong assumption that we're able to accurately
calculate latency using GETOSPACE
(buffer size - available bytes to write).

New code uses GETODELAY to get latency directly but falls back to
GETOSPACE calculation should GETODELAY fail.

The recent changes to auhal had it using an AudioStreamBasicDescription
array when looking at the stream properties. However, the proper type is
AudioStreamRangedDescription. This patch corrects that, and then accesses
the AudioStreamBasicDescription inside it as necessary.

Technically, it's either filter or search, but not search filter

add SearchLineEdit above the advanced tree that filters the tree items.

add filter function to expand and show matched tree items and hide the rest

add contains function to search text in item's name, help and in the config items' text

module initial help value was always empty, causing leading line break when appending module psz_help text.
save name and help in modules' PrefsItemData like other prefs items.

Not only is an extra console obnoxious, but freopen() crashes.

This is required for Wine to find libvlc.dll and libvlccore.dll.

Just like we already do for (Unix) vlc.

This time, it should work (famous last words).

1kHz is way too much for human perception.

This unfortunately inserts silence shortly after resuming, right after
the samples that were held in the buffer during pause. This can possibly
be avoided with prebuffering (not tested).

Fixes #3078

do not wait until a state change event

GNOME went away from freedesktop DBus interface some time ago (for the sake of being 'special' ?)
Unfortunately that means we have to support 2 different (but very similar) interfaces

(GL/gl.h ought to be present if GL/glext.h is)

AC_CHECK_HEADERS does not work the way this change assumes. This commit
did not fix the stated problem.

This reverts commit 4e33295f.

Also scale maximum down to 2 times the nominal volume (i.e. +18dB) to
stay in the recommended range of +10 to +20dB.

The formula should be changed in any case. WaveOut has a logarithmic
scale, which is not consistent with the other audio outputs.
