[Buildroot] [PATCH v2 00/11] add runtime test for mpd

[Andreas Ziegler <br025@umbiko.net>]

Testing MPD in a real world situation is fairly straightforward: build,
deploy, play some music. Representing this simple test within a test
framework is quite complex.

I tried to break down my simple test case into a few atomic steps that
interact with MPD via the built-in protocol. The necessary test data was
generated with ffmpeg and imagemagick and is royalty-free :-D

In good old usenet tradition, test data had to be split in archive
chunks, to overcome the limitations of the mailing list. The data will
be re-combined in a post-build script. 

Working on this also triggered some changes in the Buildroot setup:

The configuration file supplied by Buildroot is only a sample; it will not
start MPD on a default installation. Usually a custom mpd.conf is supplied
in a rootfs overlay. Drop the Buildroot configuration file and install the
sample supplied by MPD instead, it is more complete, contains useful
examples and is update regularly.

After various updates since version 0.20, most dependencies placing
restrictions on sub-components are now superseded by restrictions placed on
MPD itself. Example: io_uring needs kernel headers > 5.1; MPD needs kernel
headers > 5.6. Remove dependencies from sub-options if they are already
imposed on MPD. 

MPD has 99 configurable options; of these, 44 are exposed in Buildroot's
Config.in. Sort order and grouping of these options are different within
the MPD project and Buildroot, which makes a comparison difficult.
Reorder entries in Config.in to reflect their order in meson_options.txt.
Also update at least some of the help texts to more closely resemble what
is published in the MPD manual.

Changes v1 -> v2:
	split test data in chunks to overcome mailing list restrictions
