[Pkg-rust-maintainers] Bug#1025917: rust-phf: please upgrade to v0.11

[Peter Green]

I just did a preliminary analysis of the reverse dependencies and it's looking pretty good.
(details below). Though I would like to wait until I have confirmation that rust-selectors
has migrated to testing.

Matthias, would you object to me updating rust-ruma-common to 0.11.x as part of this update?

rust-chrono-tz - fixed upstream in 0.6.3 (and also higher semver-breaking versions)
rust-chrono-tz-build - fixed upstream in 0.0.3 (and other higher versions but this is the one needed for chrono-tz)
rust-coreutils - no change needed, dependency already allows 0.11 and upstream already uses 0.11
rust-cssparser - no change needed, dependency already allows 0.11 and upstream already uses 0.11
rust-markup5ever - cargo test --all --all-targets --all-features passes after dependency bump.
rust-phf-codegen - presumablly meant to be upgraded in lockstep with phf
rust-phf-generator - presumablly meant to be upgraded in lockstep with phf
rust-phf-macros - presumablly meant to be upgraded in lockstep with phf
rust-phf-shared - presumablly meant to be upgraded in lockstep with phf
rust-rust-code-analysis - already broken and not in testing
rust-selectors - RUSTC_BOOTSTRAP=1 cargo test --all --all-targets --all-features passes after dependency bump, currently undergoing it's own semver transition
rust-string-cache - cargo test --all --all-targets --all-features passes after dependency bump.
rust-string-cache-codegen - cargo test --all --all-targets --all-features passes after dependency bump.
rust-tls-parser - RUSTC_BOOTSTRAP=1 cargo test --all --all-targets --all-features passes after dependency bump and some fixes for unrelated issues.
rust-tokio-postgres - dependency patch needs dropping.
rust-ruma-common - fixed upstream in 0.11.3 (which is semver-breaking but there are no rdeps, I asked count_omega on irc if updating was reasonable, if not then I suspect patching will also be an options)
