c2178bc265 core: Cut back on hardcoded dbe_index uses
The dbe_index of a given database item might change in the future, so we
can't rely on it everywhere.  Let's just use it for saving and loading
files, with the expectation that changes will happen sometime after
startup.

Implements #69: Reduce use of dbe_index in Ocarina code

c845530812 core/queue: Resort the queue when unsetting Q_ADD_FRONT
This flag is used for bulk inserts to cut down on the number of gui
operations during startup.  Let's just make it standard that unsetting
the flag causes the queue to resort itself.

d825e2d481 core: Remove random functions
I no longer need these now that the queue is using the glib
g_random_int_range() function.

f1bcc7746e core/queue: Call g_random_int_range() rather than random_range()
Using somebody else's library is probably better than relying on my own
random number function.

This function is similar to queue_remove(), except the remove can be

5419711409 core/queue: Add qop_deinit() queue operation
This function is used to notify a higher layer that a queue is being
deinitialized.  The higher layer should then clean up any state
associated with that queue.

711eb67f44 core/queue: Fix queue random and selection test
6.4.8 changed how random tracks are selected, but never updated the unit
test.  This patch fixes the unit test, and makes a few changes to make
sure the right tracks are getting selected.

4323461bc6 core/queue: Adjust random track selection
Dividing queue size by 3 seems to give a better distribution of tracks,
but only for a large set of tracks (such as the entire collection).
let's skip the division if the queue only has a small number of tracks.
