Free the "context" pointer in the method archive_plugin.close().

Fixes a memory leak: the "archive" input plugin opens the archive, but
never closes it.  This patch moves the responsibility for doing that
to archive_plugin.open_stream().  This is an slight internal API
change, but it is the simplest and least intrusive fix for the memory
leak.

g_free(NULL) is allowed.

Fixed memory leak in error handler.

This enables valgrind debugging after an error occurred.

Enable archive plugin debugging.

This code has never made any sense, and has broken some of the archive
plugin.

Use struct forward declarations.

Don't use num_archive_plugins.

This fixes "make distcheck".

Removed local variable "sample_rate".

Not used by any plugin currently, but this eliminates the g_error()
call in input_plugin_config(), so it's worth it.

This is easier to traverse.

Wrap the AudioCompress library in a filter plugin.

Log to stderr, not to stdout (which broke PCM output).

Use the signed C99 type int8_t instead.

Mixers with the "global" flag set aren't closed automatically when the
output device is closed.  Thus, they might still be open when MPD
shuts down.

This fixes an inconsistency in the stored playlist subsystem: when
obtaining the list of playlists (listplaylist, listplaylistinfo), the
file names in the playlist directory are converted to UTF-8 (according
to filesystem_charset), but when saving or loading playlists, the
filesystem_charset setting was ignored.
