Week 0004

Quick PR to make running tests easier in uefi-rs.

Getting back to looking at the file info code in uefi-rs, I did find some bugs and things to improve. There were too many things to do it all in one PR, so I've started out with a PR containing one fix that adds unit tests. Once that's merged I'll follow up with more cleanups and improvements.

PR to add more string equality impls for CStr16 and CString16.

PR to expand the documentation of the Align trait in uefi-rs. It took me a bit to understand exactly why this trait is needed, hopefully this doc update will help someone in the future get it more quickly.

Previous set of uefi-rs PRs got merged, put up a new PR to remove some more implicit string conversions.

PR to add a changelog to uefi-rs. Covers change relevant to end users going back to the 0.14.0 release.

PR to add a small LoadedImage test.

Wrote up some more thoughts in an issue about the safety of handles in uefi-rs. Definitely a bit tricky to properly maintain guarantees in the UEFI environment.

PR to clean up the LoadedImage API and make it safer.

Did some learning about combining characters in unicode. There was an issue in uefi-rs suggesting that we might want to be smarter about where we split text output since splitting before a combining character might not render properly. Turns out that, at least on the two UEFI implementations I tested on, they don't render combining characters at all. So that makes the issue moot, which is good because fixing it properly seemed pretty tricky.

Left more details in a long comment and closed out the issue.
