I was keeping a vector of objects, and then pass pointers to these
objects around everywhere. HOWEVER, when vectors are resized they
allocate new memory and copy things over invalidating iterators and
pointers to the original objects. This can cause memory corruption
issues when I try to use a pointer to an object that no longer exists.
The simple solution? Allocate tracks dynamically and then store the
pointer in the library path.

Now that I'm using vectors for everything I don't need to maintain my
own class. Nothing uses it now, so it can be safely removed.

For each library path, I replace the linked list with a vector allowing
me to easily index into the list to find tracks.

This finishes the job I started in the last commit. Once again, I use
an enum of string properties to determine the right field to return.

I created simpler functions using the push_front() / push_back() names
that stl uses. If we're a set-type playlist, then call the
insert_sorted function instead. I also remove unnecessary bulk-inserts
of a single track. Packing and unpacking a list each time seems stupid.

Ocarina no longer has a header file subdirectory so there is no reason
to have a libsaria subdirectory anymore. Putting header files directly
in the include/ directory is a bit simpler.

I was trying to add an empty list, rather than track items. This caused
the library count to increase (on the library path tab), but the library
playlist was never given track pointers so you had to restart ocarina to
see songs.

I initially made this class so that multiple front ends could be used at
once and all receive the same notifications. I see now that this was a
stupid idea, since I only need to keep one list of the library. My
notify() function does the same stuff without the need for a driver
list.

I kept around the old list while I was converting everything over to the
new list. Now that I support all the needed features, I can remove the
old variable.

I need to check if the file is already in the library. I also made a
note for how this check could be done faster using a tree.

- Change WriteTask() to take an extra void pointer argument
- Pass library path pointer through WriteTask
- Store tracks to file named after library id.
- Remove newline from tags

I sort the subset of tracks to be added, and then use insertion sort to
add them to the playlist object.

I don't pull out the audio properties yet, but I do find artist, album,
title and everything else that I can.

This will eventually be used to determine if the track is visible based
on library path visibility.

This gives the UI a chance to set the new path or new size. I also
updated Ocarina to show the library path size in its liststore row.

This also removed the other `typedef sid_t` left in the header file.
I'll re-add in functions and variables as I need them, and hopefully
keep things working more efficiently.

I was using the sid_t to lookups for tracks and library paths. I think
I can simplify things by storing pointers in the UI rather than using
id numbers. This will give me direct access to whatever it is I want to
manipulate.

I created a new "list_dir()" function to recursively list directory
contents. I plan on using this to find songs to add to the library, but
it could also be modified to read playlists and library paths in the
appdir.

This keeps the index up-to-date with the library. Tracks are indexed as
they are scanned, then the current filter string is run through the
index again to update it.
The code was a bit messy and didn't make use of namespaces very well.
By converting to a set of functions (instead of a class) I can use
each function as a function pointer if I want to. I am also able to
remove libsaria/library.cpp since this was just a set of wrapper
functions to the old static class functions.
I don't actually perform a library update at this point, but I do create
a new task and add it to the update queue. When the run_task() function
is called, the task is removed from the queue and deleted.
