[cp-patches] Patch: fix buglet in java.net.URI (PR libgcj/21606)

[Tom Tromey]

I'm checking this in on the trunk, the 4.0 branch, and Classpath.

This fixes libgcj PR 21606.  The bug is that lower-case letters in a
"%xx"-style quote are not handled properly by URI.

The bug report came with a test case, which I checked in to Mauve.
