Add DLC refresh + restore license from Sqlite DB
DLC from ux0:addcont/ is now installed during refresh, provided there exists an sce_sys/package/
directory containing: body.bin, head.bin, inst.bin stat.bin, tail.bin, temp.bin and work.bin.
Apart from work.bin, all of these files can be be restored from the official PKG downloads, as
demonstrated by pkg_dec.
Moreover, this patch adds the ability to restore one's RIFs from an ux0:/license/licenses.db
SQLite database with the schema described hereafter (the RIF column being the uncompressed
512-byte binary license):
CREATE TABLE `Licenses` (
`CONTENT_ID` TEXT NOT NULL UNIQUE,
`RIF` BLOB NOT NULL,
PRIMARY KEY(`CONTENT_ID`)
);
With both these feature and provided that one's personal licenses have been backed up in
ux0:/license/licenses.db, Vita users can conveniently restore or reinstall their legally
owned content, straight from Sony's PKG files.
