At this moment the wavpack lib doesn't use the return value of the
push_back function, which has an equivalent meaning of the return
value of ungetc().  This is a lucky situation, because so far it
simply returned with 1 as a hard coded value.  From now on the
function will return EOF on error.  (This function makes exactly one
byte pushable back.)

A new function has been added to do a cast and a little check in the
wavpack-mpd input stream wrapper.

I think this makes the code more easily modifiable and prevents some
annoying mistakes.

There are some functions in the wavpack-mpd input streams wrapper
which had too commonly used names (especially can_seek). I prefixed
these with "wavpack_input_".

Not every function header has its return type in a distinct line. This
patch corrects that.  This way there is more space for the arguments.

The build failed when the oggvorbis and oggflac decoders were
disabled, because the flac decoder references a symbol from
_ogg_common.c.

The listen.c module breaks the build because the variable name used
("sun") for the Unix domain socket part collides with something else
on an OpenSolaris system, likely Sun specific.  Renaming it to _sun
(or something else of choice) fixes the build.

[mk: renamed to "s_un"]

Using wvc streams the seekableness depends on the seekability of the
wvc stream as well.

The input stream opened for wvc is not closed in an if branch.  A
close call has been added.

Somehow seeking is disabled on all kinds of wavpack playbacks now in
the git version.  This patch corrects that.

libcurl provides better error messages than curl_multi_strerror() when
you set the ERRORBUFFER option.

The read() method must not return a negative value.  Make it return 0
on error, just like the file input stream.  Also set the "error"
attribute to -1.

I had this option enabled during development, but at some point, it
must have gotten lost.  FAILONERROR makes the curl stream fail when
the server returns a status code 400 or higher.  We are not interested
in the server's error document.

First alpha version for the upcoming version 0.14.

The code which had a possible error condition had been removed.

When logging to a file, log_charset would be NULL and g_convert()
would abort.

Adding some of the most important changes since 0.13.

Trying to bring a little bit of structure into that list.

MPD is licensed under the version 2 of the GNU General Public License
version 2.  Also added "General".

MPD doesn't include the mp4ff library anymore.

Documented dependencies on gcc/C99, glib, libvorbisenc, liblame,
ffmpeg.

input_curl.h was missing in the tarball because it was not listed in
$(mpd_headers).

Using the logging library here is inappropriate.

When logging to the terminal, we should print messages in the system
character set.  Convert all messages in this case.

Use the bool data type for flags.

Install a default handler which writes to stdout or stderr, and
prepends a time stamp.  This looks just like the 0.13.x logger.

The logging functions from log.h are deprecated, and the code should
use GLib logging instead.  Make ERROR(), WARNING() etc. call g_logv()
internally.

Renamed the variable "logLevel" to "log_threshold".

The warning buffer is a complex piece of code for no good reason.
Remove it and find a better solution, e.g. open the log file earlier.

Initialize libc's locale functions.  Currently, we are only interested
in LC_CTYPE (character classification), because this is what is used
by GLib's g_get_charset().

Make the local variable "charset" const, and don't duplicate its
value.  It is already duplicated by path_set_fs_charset().

GLib provides the function g_get_filename_charsets() which determines
the file system character set.  This changes MPD's fallback: GLib
prefers UTF-8 as a fallback.  MPD used to fall back to ISO Latin 1.

Rename variables and functions.

Call g_thread_init() from main() to enable the GLib features which
make it thread safe.

Removed closeAllFDs().  The caller is responsible for closing all file
handles.

The output thread automatically waits some time before retrying to
open the device.  Don't duplicate this check in the pulse plugin.

The pulse plugin crashed with a segmentation fault when the pulse
server was killed.

libwavpack expects the read_bytes() stream method to fill the whole
buffer, and fails badly when we return a partial read (i.e. not enough
data available yet).  This caused wavpack streams to break.
Re-implement the buffer filling loop.
