* 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

The myfprintf bugs that are fixed here were NOT introduced in the
last patch, it's just that the stricter warning checks from moving
to fprintf caused string format bugs to actually be checked by gcc

This patch massively reduces the amount of heap allocations at
the interface/command layer. Most commands with minimal output
should not allocate memory from the heap at all. Things like
repeatedly polling status, currentsong, and volume changes
should be faster as a result, and more importantly, not a source
of memory fragmentation.
These changes should be safe in that there's no way for a
remote-client to corrupt memory or otherwise do bad stuff to
MPD, but an extra set of eyes to review would be good. Of
course there's never any warranty :)
No longer do we use FILE * structures in the interface, which means
we don't have to allocate any new memory for most connections.
Now, before you go on about losing the buffering that FILE *
+implies+, remember that myfprintf() never took advantage of
any of the stdio buffering features.
To reduce the diff and make bugs easier to spot in the diff,
I've kept myfprintf in places where we write to files (and not
network interfaces). Expect myfprintf to go away entirely soon
(we'll use fprintf for writing regular files).

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;
}
}

also, should have better error reporting when failing to open playlist or
music directory's, or writing the db, etc

also some slight optimizations to interfacePrintWithFD() and myfprintf()
git-svn-id: https://svn.musicpd.org/mpd/trunk@1503 09075e82-0dd4-0310-85a5-a0d7c8717e4f
print functions. this way we can always know wtf is going on!
also, remove some places where we were using fprintf and printf instead of
myfprintf
