I'm really no fan of the warning log, it's too complex
for how little it gets used; but fixing it is another
problem.

This is a huge refactoring of the core mpd process. The
queueing/buffering mechanism is heavily reworked.
The player.c code has been merged into outputBuffer (the actual
ring buffering logic is handled by ringbuf.c); and decode.c
actually handles decoding stuff.
The end result is several hundreds of lines shorter, even though
we still have a lot of DEBUG statements left in there for
tracing and a lot of assertions, too.

Do explicit casts before comparing signed with unsigned. The one in
log.c actually fixes another warning: in the expanded macro, there may
be a check "logLevel>=0", which is always true.

Although it may not happen in mpd code, it is perfectly possible for a
newly allocated file descriptor to be zero. For theoretical
correctness, allow 0.

This will make refactoring features easier, especially now that
pthreads support and larger refactorings are on the horizon.
Hopefully, this will make porting to other platforms (even
non-UNIX-like ones for masochists) easier, too.
os_compat.h will house all the #includes for system headers
considered to be the "core" of MPD. Headers for optional
features will be left to individual source files.

This way we'll avoid listening on fd=0 and have a better
chance of having fd=0 as /dev/null

(yes, it helps to actually compile code before committing it)

We redirect stdin to /dev/null to work around a libao bug, but
this bug has been fixed in libao since 2003 (according to jat).
However, there are likely other bugs in other libraries (and
even our code!) that handle fd=0 incorrectly and I'd rather not
take the risk[1]. So So it's easiest to just keep
fd=0==/dev/null for now...
[1] - I've seen several of these myself...

Thanks to _noth_ for the patch, this fixes Mantis bug #1534

We used a bare '15' in several places and it's not immediately
obvious where it came from. This makes it more obvious

Previously, the warning log was only flushed if creating the db or logging
to stdout. This meant that under normal circumstances (no db creation,
logging to files) the warning log was never flushed. This caused a bug
when a warning was printed for each call to the status command where the
warning buffer would grow endlessly, eventually using more and more CPU to
reallocate it.

I'll get around to it. Probably best just starting from scratch anyhow.

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.

(and fdprintf was never meant to be reentrant, either)
A huge thanks to welshbyte for reporting the bug and being very
helpful in helping me fix it.

* Moved all logging-related stuff into log.c
(and not myfprintf.c)
* ISO C90-compliant strftime usage:
%e and %R replaced with %d and %H:%M respectively
* Got rid of variadic macros since some old-school compilers
don't like them
* compiling with -DNDEBUG disables the DEBUG() macro

This shaves another 5-6k because we've removed the paranoid
fflush() calls after every fprintf. Now we only fflush()
when we need to

it indented.

These are just warnings from sparse, but it makes the output
easier to read. I ran this through a quick perl script, but
of course verified the output by looking at the diff and making
sure the thing still compiles.
here's the quick perl script I wrote to generate this patch:
----------- 8< -----------
use Tie::File;
defined(my $pid = open my $fh, '-|') or die $!;
if (!$pid) {
open STDERR, '>&STDOUT' or die $!;
exec 'sparse', @ARGV or die $!;
}
my $na = 'warning: non-ANSI function declaration of function';
while (<$fh>) {
print STDERR $_;
if (/^(.+?\.[ch]):(\d+):(\d+): $na '(\w+)'/o) {
my ($f, $l, $pos, $func) = ($1, $2, $3, $4);
$l--;
tie my @x, 'Tie::File', $f or die "$!: $f";
print '-', $x[$l], "\n";
$x[$l] =~ s/\b($func\s*)\(\s*\)/$1(void)/;
print '+', $x[$l], "\n";
untie @x;
}
}

warnings are buffered until the error log is opened, and then flushed to the
error log.
