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.

The input_stream object is opened and closed by the caller.

Disable the ffmpeg decoder plugin if avcodec_decode_audio2() is not
available.

Instead of checking the stream_types bit set, we can simply check
whether the methods stream_decode() and file_decode() are implemented.

The number of tag types is known at compile time.  Use the GLib macro
G_N_ELEMENTS instead of having a NULL element at the end.

Don't store tag type values in a plain integer, use the proper enum.

Replace deprecated code with GLib.

Instead of manually waiting for the input stream to become ready (to
catch server errors), just read the first byte.  Since the
wavpack_input has the capability to push back one byte, we can simply
re-feed it.  Advantage is: decoder_read() handles everything for us,
i.e. waiting for the stream, polling for decoder commands and error
handling.

Use boolean true/false instead of 1/0.

Renamed functions and variables.

Fixed the indent of the switch statement in format_samples_int().
