This issue occurs when playing HLS streaming delivered
from a server that does not support partial requests.
The issue is reproduced as follows(using Ubuntu 20.04 PC):

1. Prepare HLS example content.

$ mkdir test
$ ffmpeg -i example.flac -vn -c:a aac -b:a 128000 -f hls -hls_list_size 0 test/output.m3u8
(ffmpeg 4.2.4 is used)

2. Prepare web server without partial requests support.
(Docker version 20.10.12 and NGINX official Docker image is used)

$ docker run --name tmp-nginx-container -d nginx
$ docker cp tmp-nginx-container:/etc/nginx/conf.d/default.conf .
$ docker rm -f tmp-nginx-container

Edit default.conf and add "max_ranges 0;" to "location / {...}".
This disables partial requests support,
removes 'Accept-Ranges: bytes' header from the server response.
Then, run the server:

$ docker run --name test-nginx -v $PWD/test:/usr/share/nginx/html:ro -v $PWD/default.conf:/etc/nginx/conf.d/default.conf -d -p 8080:80 nginx

3. Setup MPD to Play the next URL.

http://address-of-the-server:8080/output.m3u8

Seeking this stream results in "exception: Not seekable".

AVFMTCTX_UNSEEKABLE signals the stream is not seekable

Even if the "wave_encoder" option is disabled (and no other encoder
plugins are enabled), forcefully enable the Wave encoder (if Snapcast
is enabled).

This script setup a dummy android native app folder and call ndk-gdb from it.

It needs a modification in ANDROID_NDK since ndk-gdb may attach to the wrong
pid, cf. comments in the script.

This debuggable flag should not be set with release builds. Generally, graddle
is taking care of that.

Previous versions of MPD would call SetVolume on enabled outputs before
they are ready, causing all of MPD to crash. Checking the really_enabled
flag prevents this, though it also prevents setting volume before the
player starts.

Before (with the PipeWire output):
  [i] ~$ mpc clear
  volume: 81%   repeat: off   random: off   single: off   consume: off
  [i] ~$ systemctl --user restart mpd.service
  [i] ~$ mpc volume 100
  MPD error: Connection closed by the server
  [i] ~ 1 $

After:
  [i] ~$ # mpd is freshly started w/o anything in the queue
  [i] ~$ mpc
  volume:100%   repeat: off   random: off   single: off   consume: off
  [i] ~$ mpc volume 80
  MPD error: problems setting volume
  [i] ~ 1 $ mpc
  volume:100%   repeat: off   random: off   single: off   consume: off
  [i] ~$

Previous versions of MPD would, on parameter change, set the PipeWire
volume before clearing the restore_volume flag, causing the call to
short circuit and do nothing. Instead, clear the flag before the call.

This version was released 7 years ago, and it's reasonable to require
at least this version.

Fixes -Wunused-result

Move audio output state check ahead of mixer check and force volume
applying even for disabled software mixed outputs.

This fixes incorrect software mixer volume that used to occur when
volume was changed while output being disabled.

This is easily reproduced with following sequence of commands on
multi-output software mixed MPD setup.

 mpc volume 38; mpc disable 3; mpc volume 88; mpc enable 3

On current MPD, following commands would result in output 3 playing at
volume 38, while all other enabled outputs would play at volume
88. Moreover, global volume would display average of outputs real
volumes. In my case, it's 75.

After applying this patch, following commands would produce expected
behavior. All outputs play at expected (88) volume. And volume is
correctly displayed as 88.

This is more of what we did in commit 70bd35ab because it turns
out there are Ogg-Opus files with pages larger than 40 kB.

In libFLAC 0.3.4 (commit c9530118), the "dllimport" check has been
changed from "_MSC_VER" to "_WIN32", and now the MPD build is affected
by it.

Defining FLAC__NO_DLL disables the use of "dllimport", which allows
linking properly to the static libFLAC build.
