Lib updates

[IzzySoft]

Another batch of library updates. As usual, I've kept it to one library per commit, in case you wish to cherry-pick :) As a side-effect, this also enables you to see most of the diffs via the Github web frontend, by just viewing the corresponding commit.

I'd say that's it for this batch. Please also have a look at my commit notes on:

• 05d79df: the .dat file just has a single entry for this library. I suspect it misses several, as the existing entry just references org/tukaani/xz/common, and the library has several more modules probably used by apps (e.g. lz and lzma).
• 5d53765: similarly, no entries for the other two related modules (android/content for Content Sharing and android/content/res for Resource Management)
• 3a34728: here the .dat file had several entries I could find no match for in the library code. This might very well be due to me not being a Java dev, and thus having missed something ;)

As in the past: If you can accept these changes, please merge. I'll open another batch then as soon as time permits.
