Don't use fixed static buffers.  GLib allocates a new string for us
anyway, let's just return this one instead of copying it.

The archive code was disabled, because config.h was not included and
thus ENABLE_ARCHIVE was not defined.

Save an empty database, even if the music directory is empty.

Use the PCM buffer library for the libsamplerate output buffer.

Return a temporary buffer from pcm_resample_*() and pcm_convert().

Replace a "static" buffer with the PCM buffer library.

Replace a "static" buffer with the PCM buffer library.

This library allocates temporary buffers for storing PCM conversion
results.  It should replace all those "static" buffer variables which
are racy and never freed.

Be sure that the output thread has quite before we start destructing
the output object.

Free memory allocated by the notify object (GMutex, GCond) when it's
not used by the output object anymore.

Free memory allocated by libsamplerate when the output or the decoder
is closed.

1024 is 2^10, and allows gcc to use bit shift operations instead of
multiplication / division.

In generic PCM functions allowing all sample formats, pass a void
pointer instead of a char pointer.

All what's left in pcm_utils.h is the pcm_range() utility function,
which is only used internally by pcm_volume and pcm_mix.

The function does not need the full pcm_convert_state struct.

Moved all code which converts the sample format to a separate library.

Moved the software mixing code (used by crossfading) to a separate
library.

Moved the software volume code to a separate library.

We are going to split the pcm_utils.c library, and pcm_range() will be
useful for several sub libraries.

Get rid of the non-portable Linux list library, part III (final).

Get rid of the non-portable Linux list library, part II.

Get rid of the non-portable Linux list library, part I.

Fix a typo in the icy-metadata patch.

Declare and initialize MPD_LIBS and MPD_CFLAGS before the "OS specific
defaults" section.

Both are unused.

Yesterday's patch set changed tagItemFoundAndMatches() and moved the
strcmp() return value into a bool, but forgot to add the ==0 check.

"#ifdef G_BYTE_ORDER == G_BIG_ENDIAN" cannot work, of course.

Zeroconf, curl, libsamplerate.  No libid3tag for now, because
libid3tag should be automatically disabled when no decoders using it
are enabled.

Don't separate basic options from their according tests.  Due to lots
of interdependencies, we won't do that for the plugins yet.

Print input plugins first, then archive, metadatab, decoder,
converter, encoder, output plugins.

Initialize the CFLAGS (warnings, errors) after all the libraries,
because some library checks may be broken with -Werror or -pedantic.

AC_CHECK_HEADERS defines HAVE_LOCALE_H, so we don't have to manually
define HAVE_LOCALE.

First do the checks for mandatory stuff (libc features, glib,
pkg-config), then all the options.

Don't check for inttypes.h and langinfo.h.
