music: rework id system
Completely rework the ID system to pave the way to MusicBrainz ID
support and greatly increase ID integrity in general.

This changeset removes the old ID field, an emulation of a polynomial
hash that was used in all items, and replaces it with a new type called
UID that is specific to Music. Other types just use plain equals now,
and most instances of "id" to check for equality in the app have either
been inlined into an equals override or removed outright.

The new UID format is as follows:
datatype/format:uuid

Datatype is a tag that is just the lowercase tag name. For example,
"song". Format is the program that created the UID. auxio will be an
md5 hash, and musicbrainz will the a musicbrainz ID extracted from a
file. UUID is the uuid itself.

This is much more reliable and extendable than the old ID format. This
will also be the last time I break compat with old ID formats. From now
on, a legacy UID field will not be included to enable backwards compat,
when the time comes for a breaking change.
