Market test suite works for @evik42 24 commits behind master at Rust 1.64.0

#2280 fixes all issues.

1. The unhappy path taken when backtrace doesn't parse properly. The issue was that all market tests with deduced names (MarketsNetwork::new(None), 116 occurances as of now) will have auto-gen'd ones of the form unknown-test-{:#32x}, because the bactrace does not conform to the assumptions made when the name deduction was first written.
   A proper fix would parse the new backtrace format or, even better, not use backtraces for this at all, as symbol names do not have a guaranteed structure.
   Followed up in Rethink MarketsNetwork::new name deduction #2282.

2. A bug in cargo made the valid flag split-debuginfo="unpacked" cause windows builds to fail, so I removed it from Cargo.toml with an appropriate remark. This should be reverted when my fix in cargo is merged and published Fix split-debuginfo support detection rust-lang/cargo#11347.

3. Removed -D warnings from clippy. This largely defeats the purpose of using clippy, but we just can't have that with automatically updated toolchain, as new / broadened lints will pose a risk to CI on every update. Continued in Enforcing clippy may break CI on each update #2281.
