Bug 1514247 - Upgrade u2f-hid-rs to 0.2.3 r=emilio,keeler This patch moves u2f-hid-rs to 0.2.3 [1], which changes the dependency graph of u2f-hid-rs to not directly rely on the low-level core-foundation-sys library, as core-foundation has all the features u2f-hid-rs needs in 0.6.1+. This patch vendors core-foundation 0.6.3 and core-foundation-sys 0.6.2 as a consequence. [1] https://github.com/jcjones/u2f-hid-rs/releases/tag/v0.2.3 [2] https://github.com/jcjones/u2f-hid-rs/commit/d1d36d10442b0850f5ea9f5111a41b519fc5fee4 Differential Revision: https://phabricator.services.mozilla.com/D14569
