[Bug-gnuzilla] Rust issues

[David Michael]

Hi,

With Rust enabled, the IceCat build fails when Cargo verifies the
vendored crates' files' SHA-256 sums due to the s/Firefox/IceCat/g run
on the source.  Specifically, this can be fixed with:

sed -i -e s/IceCat/Firefox/g third_party/rust/idna/src/lib.rs

That command restores the original file's text so the SHA-256 tests
pass again.  (It only modifies a comment.)

Is there a preference on how this should be addressed for the future?
I suppose some options are to:

- Skip modifying vendored crates (which could be bad as more of
Firefox is rewritten in Rust)
- Overwrite .cargo-checksum.json files with an empty file list to skip
verification
- Parse and edit the JSON files to test the SHA-256 values of modified files

Thanks.

David

P.S.
It also needs something like adding "build = false" to
media/libstagefright/binding/mp4parse_capi/Cargo.toml as in upstream
bug #1338655 to work with current Cargo.
