…lement Clone and Drop for it.

…r=eddyb Refactor C FFI variadics to more closely match their C counterparts, and add Clone implementation We had to make some changes to expose `va_copy` and `va_end` directly to users (mainly for C2Rust, but not exclusively): - redefine the Rust variadic structures to more closely correspond to C: `VaList` now matches `va_list`, and `VaListImpl` matches `__va_list_tag` - add `Clone` for `VaListImpl` - add explicit `as_va_list()` conversion function from `VaListImpl` to `VaList` - add deref coercion from `VaList` to `VaListImpl` All these changes were needed for use cases like: ```Rust let mut ap2 = va_copy(ap); vprintf(fmt, ap2); va_end(&mut ap2); ```
…s, r=nikomatsakis Add better tests for hidden lifetimes in impl trait cc rust-lang#60670
tests: Centralize proc macros commonly used for testing Many proc macros in `ui\proc-macro\auxiliary` were doing same things. (I added a fair share of those myself.) Now commonly used macros (empty, identity, etc) are collected in one place - `ui\proc-macro\auxiliary\test-macros.rs`.
…a-discard_buffer, r=nikomatsakis BufReader: In Seek impl, remove extra discard_buffer call As far as I can tell, this code does nothing. I'm not sure why it even is there.
…atsakis Mailmap fixes I've made a few fixes and additions to the .mailmap file. - I've added my information to it, as I noticed it was popping up twice at the [Thanks](https://thanks.rust-lang.org/rust/all-time/) website (I've made contributions to the Rust Book). - I noticed that @carols10cents‘ information was popping up in multiple places at the [Thanks](https://thanks.rust-lang.org/rust/all-time/) website and when running `git shortlog -s -e > out.txt`, and fixed her information - I alphabetized the list using Atom's [Sort Lines package](https://github.com/atom/sort-lines) The output from before and after running `git shortlog -s -e > out.txt` for Carol: <img width="708" alt="Carol Before" src="https://user-images.githubusercontent.com/19867440/58472843-2d8ca880-8115-11e9-9624-d31ed23ae9b5.png"> <img width="523" alt="Carol After" src="https://user-images.githubusercontent.com/19867440/58472844-2d8ca880-8115-11e9-95c6-80b17cc04790.png"> The output from before and after running `git shortlog -s -e > out.txt` for myself: <img width="489" alt="Joseph After" src="https://user-images.githubusercontent.com/19867440/58472941-6e84bd00-8115-11e9-8266-1d7fcd53d0bc.png"> <img width="421" alt="Joseph Before" src="https://user-images.githubusercontent.com/19867440/58472943-6e84bd00-8115-11e9-9fd2-d7ace7e3d636.png">
