g_set_error() is a printf-like function, and expects a format string.
Using the return value of gai_strerror() is unsafe.

Move the declaration of "i" into the "for" loop.

The environment variable MAKE can be set by the caller process, and
may be used to pass a concurrency value (-j).

Cuesheets are often saved as vorbis comment
flac files (CUESHEET=.. case doesn't matter).
We can parse this now and use the information to
tag the subtracks (from the embedded cuesheets).

Autoconf/automake support for libcue which
is needed for cue/cue_tag.h/.c.
Libcue will have/has pkg-config support
so this is fairly straightforward.

With these methods a tag struct can be created
from the cdtext information in a cue sheet.
The methods depend on a cue parsing library.
Reading from strings (char*) as well as from
a file (FILE*) is supported.

This is a little ugly, but as nextSongInPlaylist is both called when
queued is update (in case playlist ended) and for user "next" command,
there isn't any other (simple) solution

Consume mode removes each song played

In the MPD_AUTO_DISABLED() function, I forgot to check for "explicitly
disabled".

Ths usual defaults updates, this includes clarifications, cleanups, updates
and fixes.

MPD_AUTO_PKG() runs pkg-config and then forwards control to
MPD_AUTO_RESULT().  This is a commonly used short cut.

Don't add those to MPD_CFLAGS and MPD_LIBS.

This patch adds a small autoconf M4 library which deals with
auto-detected features.  The default for those features is "auto",
which is like the old default: if the library is present on the
system, enable the feature, disable otherwise.  If the user explicitly
enables that feature (--enable-alsa), and the library is not present,
configure must fail, because it cannot fulfill the request.

Previous cast to float didn't have any effect because one value is uint
and the other is a floating type but the number itself is even..
This caused some tracks to end before they were really at an end.
