f0e64ceb48 use strset.h instead of tagTracker.h
With a large music database, the linear string collection in
tagTracker.c becomes very slow.  We implemented that in a
quick'n'dirty fashion when we removed tree.c, and now we rewrite it
using the fast hashed string set.

4665f2bf32 tag: don't pass "fd" to printVisitedInTagTracker()

dc8b64fdef pass "struct client" to dbUtils.c, song.c, tag_print.c
Don't pass the raw file descriptor around.  This migration patch is
rather large, because all of the sources have inter dependencies - we
have to change all of them at the same time.

f320c9fa1d directory: don't pass fd to traverseAllIn()
This patch continues the work of the previous patch: don't pass a file
descriptor at all to traverseAllIn().  Since this fd was only used to
report "directory not found" errors, we can easily move that check to
the caller.  This is a great relief, since it removes the dependency
on a client connection from a lot of enumeration functions.

528be8a0a9 directory: don't pass fd to traverseAllIn() callbacks
Database traversal should be generic, and not bound to a client
connection.  This is the first step: no file descriptor for the
callback functions forEachSong() and forEachDir().  If a callback
needs the file descriptor, it has to be passed in the void*data
pointer somehow; some callbacks might need a new struct for passing
more than one parameter.  This might look a bit cumbersome right now,
but our goal is to have a clean API.

8d2830b3f9 playlist: don't pass "fd" to playlist.c functions
The playlist library shouldn't talk to the client if possible.
Introduce the "enum playlist_result" type which the caller
(i.e. command.c) may use to generate an error message.

75aa8dad4c song: moved code to song_print.c, song_save.c
Move everything which dumps song information (via tag_print.c) to a
separate source file.  song_print.c gets code which writes song data
to the client; song_save.c is responsible for serializing songs from
the tag cache.

Getting rid of CamelCase; not having typedefs also allows us to

a383f45117 enable -Wpointer-arith, -Wstrict-prototypes
Also enable -Wunused-parameter - this forces us to add the gcc
"unused" attribute to a lot of parameters (mostly library callback
functions), but it's worth it during code refactorizations.

c5b524e376 eliminated duplicate initialization
Local variables which are never read before the first assignment don't
need initialization.  Saves a few bytes of text.  Also don't reset
variables which are never read until function return.

2f0e5bfd85 addToPlaylist/addSongToPlaylist: printId argument changed to added_id
Instead of printing out the Id from playlist.c, instead set
the integer that added_id poitns to if added_id is non-NULL.

This makes the API cleaner and will allow us to use additional
commands to manipulate the newly-added song_id.  Callers
(handleAddId) that relied on printId to print it to the given
fd have now been modified to print the ID at a higher-level;
making playlist.c less-dependent on protocol details.

90847fc881 Replace strdup and {c,re,m}alloc with x* variants to check for OOM errors
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.

4cf5d04ca1 interface/connection malloc reductions from mpd-ke
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).

a234780aab sparse: ANSI-fy function declarations
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;
}
}

then print out the visited tags in tag tracker (which has the benefit of
making sure everything is in sorted order)

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
