NOTICE: Changeover from CC0 to another compatible license

Need to pick a license just out of courtesy. Note to downstream users: Your existing rights and those to future versions will not be affected by this change. I don't have any patents, period, but switching to a license that implicitly grants them (presumably via the first-party doctrine) would be ideal just as accident avoidance.

For the record, BSD0's the current one I'm thinking of changing to, though MIT0 is on the table. This change will also affect gabien and therefore by extension the TTS project.

Another option is the Unlicense, similar to CC0 (Fedora suggests this one as a closer replacement).

@fdelapena Regarding Unlicense: Good point, good point ...I admit I kind of forgot about this license change plan (there's a lot of notices to change over, since R48 has a license header on each file)

@rohkea You're on the contributors list, so I'm checking this with you before I finally commit this: Is it okay to relicense R48 to the Unlicense? EDIT:

I'm totally OK with changing the license, either to Unlicense or to any other license

[20kdc]

I took a while to get around to this, but on the flip-side that just means notice was given for a long time, so that's probably for the best.

So it turns out that a CC0-based component ( https://github.com/lieff/minimp3/blob/master/minimp3.h ) is also the best shot at MP3 support. There is, at least, the possibility of providing an alternate libmpg123-based configuration should Fedora ever need it, though such a thing would essentially be a separate "classical build" of the natives specific to Linux users. Due to some particularly awkward issues with how the cross-compilation is setup, especially since it needs to be "decoupled" from Linux glibc in order to function properly on all systems, simply pulling in a larger library like libmpg123 might be technically infeasible, not to mention the licensing situation.
