[mk: backwars compatibility and autoconf check]

Requires YAJL to build, and this doesn't include the necessary
automake changes. Can be built using
./configure CFLAGS="-I/usr/include/yajl" LIBS="-lyajl" --enable-soundcloud

Add the following to your config:

playlist_plugin {
        name "soundcloud"
        enabled "true"
        apikey "c4c979fd6f241b5b30431d722af212e8"
}

Then you can stream from soundcloud using calls like:

mpc load soundcloud://track/<track-id>
mpc load soundcloud://playlist/<playlist-id>
mpc load soundcloud://url/http://soundcloud.com/some/track/or/playlist

For the last case, you can leave off the http:// or
http://soundcloud.com/ .

To replace libcue, the unmaintained and crashy library.

Replace -I with -isystem in GLIB_CFLAGS.

It appears the musepack section has not really been reviewed in some
time, many parts unfunctional, others, just unnecessary.

Ensure that WINVER is defined early enough, so other system headers
won't fall back to their default value.  Specifically, this solves a
build failure (-Werror) with mingw-w64 ("WINVER redefined").

Prepare for enabling "silent-rules".

Don't use MPD_LIBS, MPC_CFLAGS.

Don't use MPD_LIBS.

Use DESPOTIFY_LIBS in Makefile.am instead.  Also, use
DESPOTIFY_CFLAGS.

gprof is obsolete, it's better to use perfcounters in every aspect.

AC_SEARCH_LIBS allows the function to be present in libc.

One call to AC_SEARCH_LIBS replaces AC_CHECK_FUNCS and AC_CHECK_LIB.

Defaulting to "with systemd" causes problems for users who install MPD
as an unprivileged user, and it breaks "make distcheck".  It looks
like enabling it by default creates too many practical problems for
unexperienced users.

With --with-systemdsystemunitdir (without a parameter), configure.ac
attempts to auto-detect systemd.

Allow enabling the plugin explicitly without running Solaris, to test
the build.

Wrong variable name.

Add -DNDEBUG to AM_CPPFLAGS.
