The function flac_vtrack_tnum() was missing a strrchr()==NULL check.

Allow RIFF/AIFF ID3 tags up to 4 MB (old limit was 256 kB).  This
might still be too small for some users, and when somebody complains,
we might do something more clever (like streaming the data into
libid3tag?).

On some platforms, libavcodec wants the output buffer aligned to 16
bytes (because it uses SSE/Altivec internally).  It will segfault when
you don't obey this rule.

If flac_container_decode() gets a seek destination which is out of
range, it ignores the SEEK command (never finishes it).  This leads to
MPD lockup, because the player thread waits for completion.

The oggflac plugin has been completely broken for quite a while and
nobody has noticed - maybe we should remove it?

We need the function zzip_file_stat().

We're using API functions which are not available in 0.3.

This function was not present in SQLite < 3.4.

Should be "lastfm_user", not "lastfm_username".

The line buffer had a fixed size of 5 kB, and was allocated on the
stack.  This was too small for some users.  As a hotfix, we're
increasing the buffer size to 32 kB now, allocated on the heap.  In
MPD 0.16, we'll switch to dynamic allocation.

Convert the metadata with the libavformat function av_metadata_conv().
This ensures that canonical tag names are provided by libavformat, and
we can remove the "artist" vs "author" workaround.

When you disable the "follow_outside_symlinks" or the
"follow_inside_symlinks" setting, the next update should remove the
now-ignored files from the database.

Basically the same as the 0.15.5 patch "check again if output is open
on CANCEL".  Same race condition, same fix.

Don't initialize "vc" and "cs" with FLAC__metadata_object_new(); that
value is overwritten by FLAC__metadata_get_tags() and
FLAC__metadata_get_cuesheet().

The return value of map_directory_child_fs() must be freed.

Removed the NULL check.  If that NULL check was correct, that would
have been a memory leak (vtrack).

When the player thread unpauses, it sends CANCEL to the output thread,
after having checked that the output is still open.  Problem is when
the output thread closes the device before it can process the CANCEL
command - race condition.  This patch adds another "open" check inside
the output thread.

When the connection is lost while buffering, the CURL input plugin may
enter an endless loop, because it does not check the EOF condition.
This patch makes fill_buffer() return success only if there's at least
one buffer, which is enough of a check.x

On 32 bit systems with large file support enabled (i.e. "sizeof(off_t)
> sizeof(size_t)") gcc emits a warning because a size_t cast to off_t
can never become negative.

When there is no Content-Type response header, try the "mad" decoder
plugin.  It uesd to be named "mp3", and we forgot to change the
fallback name in decoder_thread.c.

When a received chunk of data has only icy-metadata, there was no
usable data left for input_curl_read() to return, and thus it returned
0 bytes.  "0" however is a special value for "end of file" or
"error".  This patch makes input_curl_read() read more data from the
socket, until the read request can be fulfilled (or until there's
really EOF).

Usually, we read our "artist" tag from ffmpeg's "author" tag.  In some
cases however (e.g. APE), this tag is named "artist".  This patch
implements a fallback: if no "author" is found, MPD tries to use
"artist".

When the ID3 tag in an AAC file is larger than the current buffer, the
function decoder_buffer_consume() aborts.  By using the new function
decoder_buffer_skip() instead, we can safely skip the ID3 tag.

Include CoreServices/CoreServices.h.

The update job id is positive.  When used in a command list, MPD
prints one job id for each "update" command.

Add a second column of comment signs on some parameters which users
shouldn't usually set, unless they know what they're doing.

This patch made ov_time_total() unusable, and MPD did not know the
duration of songs.

using ov_test_callback with function CALLBACKS_STREAMONLY will cause
scanning to stop after the comment field.  ov_open (and ov_test)
default to CALLBACKS_DEFAULT which scans the file structure causing a
huge slowdown.  The speed improvement is huge: It scanned my files
around 10x faster This procedure has been recommended by monthy (main
vorbis developer) and was said to be safe for scanning files.
