DECODE_STATE_STOP is always set as dc->state, and dc->stop
is always cleared. So handle it in decodeStart once rather
than doing it in every plugin.
While we're at it, fix a long-standing (but difficult to
trigger) bug in mpc_decode where we failed to return
if mpc_decoder_initialize() fails.

thread-safety work in preparation for rewrite to use pthreads
Expect no regressions against trunk (r7078), possibly minor
performance improvements in update (due to fewer heap
allocations), but increased stack usage.
Applied the following patches:
* maxpath_str for reentrancy (temporary fix, reverted)
* path: start working on thread-safe variants of these methods
* Re-entrancy work on path/character-set conversions
* directory.c: exploreDirectory() use reentrant functions here
* directory/update: more use of reentrant functions + cleanups
* string_toupper: a strdup-less version of strDupToUpper
* get_song_url: a static-variable-free version of getSongUrl()
* Use reentrant/thread-safe get_song_url everywhere
* replace rmp2amp with the reentrant version, rmp2amp_r
* Get rid of the non-reentrant/non-thread-safe rpp2app, too.
* buffer2array: assert strdup() returns a usable value in unit tests
* replace utf8ToFsCharset and fsCharsetToUtf8 with thread-safe variants
* fix storing playlists w/o absolute paths
* parent_path(), a reentrant version of parentPath()
* parentPath => parent_path for reentrancy and thread-safety
* allow "make test" to automatically run embedded unit tests
* remove convStrDup() and maxpath_str()
* use MPD_PATH_MAX everywhere instead of MAXPATHLEN
* path: get rid of appendSlash, pfx_path and just use pfx_dir
* get_song_url: fix the ability to play songs in the top-level music_directory

We need to SIGCONT the decoder process to allow for seeking
while paused.

The problems I had were related to the OSS driver and USB
device I was using. The problems existed even with the old
busy-waiting scheme enabled.
OSS - Bithead USB => bad
ALSA - Bithead USB => OK
OSS - Onboard i8x0 => OK
ALSA - Onboard i8x0 => OK
bad - slow shutdown, pauses, dropped audio after pause/resume

Until we can fix it properly (or replace it with a cleaner event
system), I don't want this in trunk. Currently there are
strange pauses when queueing and during shutdown that I can't
seem to figure out right away.

As unfortunate as it is to remove such useful debugging messages, it's
necessary to fix a potential deadlock with signal handling. A bunch of
functions the debug functions call aren't safe to call from a signal
handler. There are some alternate solutions, but they're neither pretty
nor simple. So just remove them entirely for now.

as with the stop command, this will cause the player and decoder
to suspend and not wake up hundreds of times a second to poll
a variable for wakeup. This will reduce power consumption
on some CPUs while mpd is paused and not playing.
tests:
pause && unpause => OK
pause && stop && play => OK
pause && exit && restart w/statefile && unpause => OK
pause && block sound device && \
unpause => failed to open sound device \
=> still paused and suspended => unblock sound device &&
unpause => OK (playing)
In all cases, the player process releases the audio device
when paused before going into the suspended state.

Currently, if we start decoding while the pause flag is set, we open the
audio device and leave it opened, blocking other apps from using it. The
obvious thing to do is to not open the audio device if the pause flag is
set, but the open call also sets the audio format. Therefore I'm leaving
the open call in, and just closing it immediately afterwards if the pause
flag is set.

Only wavpack implements both fileDecodeFunc and streamDecodeFunc, and it's
fileDecodeFunc provides more functionality. So try using that first.
This commit also fixes a bug where the plugin test loop wouldn't break once
a suitable plugin was found if it used fileDecodeFunc.

it's a local variable and can't be modified externally, it'll never be hit.

they're needed again. Then send them SIGCONT instead of re-spawning them.

Some compilers and linkers aren't smart enough to optimize this,
as global variables are implictly initialized to zero. As a
result, binaries are a bit smaller as more goes in the .bss and
less in the text section.

This fixes a bug where streams that won't play somehow appear with the
metadata of a previously played stream. As far as I can tell, the only
reason this is done is to sync any buffered metadata with the displayed
metadata when decoding stops, so there should be no other adverse effects.

I'm checking for zero-size allocations and assert()-ing them,
so we can more easily get backtraces and debug problems, but we'll
also allow -DNDEBUG people to live on the edge if they wish.
We do not rely on errno when checking for OOM errors because
some implementations of malloc do not set it, and malloc
is commonly overridden by userspace wrappers.
I've spent some time looking through the source and didn't find any
obvious places where we would explicitly allocate 0 bytes, so we
shouldn't trip any of those assertions.
We also avoid allocating zero bytes because C libraries don't
handle this consistently (some return NULL, some not); and it's
dangerous either way.

utf8ToFsCharset() and fsCharsetToUtf8() got very broken in r4311, and
resulted in several commits to fix those leaks. Unfortunately, not all
of those newly introduced leaks were fixed, nor was the result pretty.
Also, fixed a double-free in lsPlaylists(). This is very hard
to trigger (and therefore exploit) at the moment because we
check printDirectoryInfo() beforehand.
Intended behavior for utf8ToFsCharset() and fsCharsetToUtf8() as
God^H^H^Hshank originally intended is now documented in path.h
to prevent future errors like this.
mpd could still use some good valgrind testing before the 0.12.0
release.
<plug>In addition to reducing heap fragmentation, malloc
reductions from mpd-ke greatly reduces the chance of leaks from
happening due to programming errors.</plug>

strncpy isn't really safe because it doesn't guarantee null termination,
and we have had to work around it in several places.
strlcpy (from OpenBSD) isn't great, either because it often leaves
errors going unchecked (by truncating strings).
So we'll add the pathcpy_trunc() function with is basically strlcpy
with a hardcoded MAXPATHLEN as the limit, and we'll acknowledge
truncation since we only work on paths and MAXPATHLEN should be
set correctly by the system headers[1].
file-specific notes:
inputStream_http:
eyeballing the changes here, it seems to look alright but I
haven't actually tested it myself.
ls:
don't even bother printing a file if the filename is too long
(and when is it ever?) since we won't be able to read it anyways.
metadataChunk:
it's only metadata, and it's only for showin the user, so truncating
it here souldn't be a big issue.
memset to zero in init is unecessary, so lets not waste cycles
[1] - If the system headers are screwed up, then we're majorly
screwed regardless of what we do :x
