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.

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.

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.

playerData.c:
proper error checking
directory.c:
properly check myFgets() for errors
(it returns NULL on error)
inputPlugins/mp3_plugin.c
get rid of commas at the end of enums
interface.c:
we weren't using long long, so strtoll isn't needed
get rid of void-pointer arithmetic
sllist.c:
get rid of void-pointer arithmetic
compress.c:
get rid of C++ comments, some compilers don't accept them
Note that I personally like void pointer arithmetic, but some
ancient compilers don't support them :(

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

stripped binary size reduced by 9k on my machine from making
commandError a function. We'll print out error messages slightly
slower before, but the smaller binary is more than worth it.

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).

We never used many features from it, so there's no point in
keeping it and forcing people to install a non-standard library.
It may be standard on many GNU/Linux distributions, but there
are many other UNIXes out there. This makes life much easier
for people cross-compiling (like me :)

this code needs some serious testing:
Note:
The song name optimization i think is worth it, saves about 200k of ram on my syste, however, having to create directory names iteratively each time we print probably isn't worth the cpu. We only save about 10k of ram for the computer todo alot more work, and the code maybe a little messier

Here, i've made readDirectoryDB detect when stuff is deleted, added and updated.
So after a update, and we call redDirectoryDB, we update the db instead of
just adding stuff w/o "updating" and "deleting" stuff as neccessary.
