Add more license annotations

[pietroalbini]

This PR updates the .reuse/dep5 file to include more accurate licensing data for everything in the repository (excluding submodules and dependencies). Some decisions were made in this PR:

• The standard copyright attribution for files maintained by us is "The Rust Project Developers (see https://thanks.rust-lang.org)", to avoid having to maintain an in-tree AUTHORS file.
• For files that have specific licensing terms, we added the terms to the .reuse/dep5 rather than adding SPDX comments in the files themselves.
• REUSE picks up any comment/text line with Copyright on it, so I had to sprinkle around REUSE-IgnoreStart and REUSE-IgnoreEnd comments.

The rendered COPYRIGHT file is available at https://gist.github.com/pietroalbini/efb81103f69596d39758114f3f6a8688.

I reviewed this and was not clear about the policy/plan for the blocks surrounded by REUSE-IgnoreStart/REUSE-IgnoreEnd, so I asked @pietroalbini about it on Zulip over here.

Executive Summary: The ignore directives are used to stop the REUSE tool from using the ignore-annotated copyright statements in question when building its resulting report. (as in, "it makes the tool ignore these blocks"). There are two scenarios where it is "okay" to ignore such statements:

• Old copyright statements that don't match our current templates.
  • These should be ported forward to use the new standard copyright statement that is understood by the REUSE tool.
• Text that is itself not a copyright statement (at least not about the file in question), but matches the REUSE templates and thus would be picked up without an ignore directive. @pietroalbini gives the example of src/doc/footer.inc, which includes text that is is auto-injected into the generated documentation in order to establish the copyright of the generated documentation, but that text is not itself the copyright assignment for src/doc/footer.inc.
  • These should either be "tweaked" to "appease" REUSE (which I take to mean "rewrite the text/code such that REUSE stops pattern matching these cases") or should keep the ignore-directives. (I think the specific example of src/doc/footer.inc sounds like a scenario where keeping the ignore-directive makes sense. We probably need to consider each such instance on a case-by-case basis, rather than applying a blanket policy for the long-term.)

I also asked Pietro whether our goal was to remove licenses entirely, or to replace licenses with spdx headers. Pietro said that they'd love in the long-term to have spdx headers in every file, but for the short term the focus is to minimal number of changes to get our repository into compliance (and I agree with that.) Overall, these spdx headers seem to require on the order of two lines of machine-parsed comments, so the aforementioned long-term plan seems reasonable to me

It is now in the queue for this repository.

FWIW these are copies of old rust source files, that had their license headers removed in rustc at some point but that change was never synced to Miri. So now this 'fork' has the SPDX header but the original file that still exists in rustc does not... it'd be more consistent to just remove the license header here without adding SPDX headers. But either way is fine for me.

[pietroalbini]

The rule of thumb I used is to keep the SPDX header for files that will end up outside of the monorepo, while removing it from files that will be kept only inside (i.e. rust-installer, which was straight up imported).
