std: sys: fs: uefi: Implement rename
b725981 
- Using the file_name field in `EFI_FILE_INFO` works for renaming, even
  when changing directories.
- Does not work for cross-device rename, but that is already expected
  behaviour according to the docs:

  "This will not work if the new name is on a different mount point."

- Also add some helper code for dealing with UefiBox<file::Info>.
- Tested using OVMF in qemu.

Update cell.rs, correct module level doc

This change corrects the Cell<T> section by replacing `&mut` with `&` so the statement reads "an &T to the inner value can never be obtained". It also emphasizes that a single &mut T to the inner value can be obtained (e.g. via method core::cell::Cell::get_mut).

What is this? This is an experimental post-merge analysis report that shows differences in test outcomes between the merged PR and its parent PR.

Comparing 0d162b2 (parent) -> 9e8a0c5 (this PR)

Test differences

Show 240 test diffs

240 doctest diffs were found. These are ignored, as they are noisy.

Test dashboard

Run

cargo run --manifest-path src/ci/citool/Cargo.toml -- \
    test-dashboard 9e8a0c51641114b46b2dba657a121b2483b5aee3 --output-dir test-dashboard

And then open test-dashboard/index.html in your browser to see an overview of all executed tests.

Job duration changes

  1. dist-apple-various: 3926.8s -> 4738.0s (+20.7%)
  2. dist-x86_64-apple: 7964.3s -> 9550.0s (+19.9%)
  3. tidy: 152.1s -> 176.0s (+15.7%)
  4. x86_64-gnu-gcc: 3887.6s -> 3370.9s (-13.3%)
  5. aarch64-msvc-1: 6831.1s -> 7731.8s (+13.2%)

  9. dist-various-2: 2166.4s -> 2351.5s (+8.5%)
  10. dist-x86_64-netbsd: 5279.1s -> 4832.3s (-8.5%)
How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
