We want to remove gcc.h eventually. This takes care of all the
G_LIKELY/G_UNLIKELY macros.

Commit dd7711d8 removed MPD's default ALSA buffer_time.  The result
was a buffer size which was way too small for playing streams on some
sound hardware, and caused skips and distorted sound.  Revert the
default to 500 ms.

Moved the following developers to the "Former Developers" section,
because they are currently not interested in MPD development: Warren
Dukes, J. Alexander Treuman.

There are probably more inactive developers still in the list.

The AUTHORS file should only contain full real names.  Removed all
pseudonyms.

libmp4ff was removed from MPD a while ago.

"float (*lamebuf)[2] = g_malloc()" does NOT allocate two float*
buffers.  The formula is even wrong: it should be applied to LAME's
output buffer, not its input buffer.

Converted "lamebuf" to the two variables "left" and "right", and
allocate them independently with the exact buffer size.  Set
right=left if mono output is configured.

It's easier to work with an int16_t* pointer here.

Follow HTTP redirects, but no more than 5.

Send "Music Player Daemon " + VERSION as the User-Agent request
header.

The configuration options "follow_outside_symlinks" and
"follow_inside_symlinks" let the user control whether MPD should
follow symbolic links in the music directory.

[mk: converted variables to "bool"; moved configuration to
update_global_init()]

Mention the workaround for users without pkg-config.

Those two functions are called when MPD starts and exits.  It allows
the update library to perform global initialization and
deinitialization.  The implementations are currently empty.

In contrast to, getBoolConfigParam(), config_get_bool() properly
returns a "bool" value.  In case of "unset", it returns the default
value provided by the caller.

Use GLib's g_warning(), ... instead of MPD's deprecated log.h.

input_curl.c does not support parsing shoutcast metadata yet.  Disable
the "Icy-Metadata" header for now, since it may cause corruptions in
the stream.

Make valgrind happier.

If the shout plugin is disabled, shout_plugin.c isn't compiled at all,
no need to check the macro definition.

I have found something that looks like a bug in MPD:
- When a song is finished, the next one is played and the 'player'
  event is emitted.
- When the client sends the status command just after this event, the
  songid is the new one but the 'elapsed' time is not reseted to 0.

This is problem because I have implemented the solution using a timer
on client side to compute the elapsed time but with this bug the
elapsed time continues to be incremented on a new song.

When ao_open_live() failed, MPD would ignore the error code in
"errno".  Make it print a meaningful error message.

The function audioOutputAo_error() did not implement all possible
libao error codes.  Support the rest of them, and fall back to
strerror().
