add HermitCore support even if it doesn't have a UNIX interface
Currently, we redefine the interface between the HermitCore kernel (https://hermitcore.org) and Rust’s standard library. In the future, it will not depend on a POSIX-compatible C library. Consequently, we add the support of HermitCore if the "unix" environment isn’t set. It will be great to integrate this patch because it would simplify our development. The classical interface is still supported and part of the subdirectory "unix".
adjust PTHREAD_STACK_MIN to current value on OpenBSD
adjust `PTHREAD_STACK_MIN` to current value on OpenBSD, and while here, generate the right file in test_openbsd()
I should say that I am a bit disappointed. If I didn't miss anything, the related change for `PTHREAD_STACK_MIN` is near to one year old. And clearly with the name error in `test_openbsd()` something wasn't clean.
Verify that only non-technical breaking changes are applied to libc
Closes#270 .
cc @alexcrichton so this would be a solution to #270 that uses rust-semverver to check that the API of `libc` contains only non-technical breaking changes.
This is a WIP and uses a fork of `rust-semverver` for now, but I've sent PRs upstream already. This is the only idea I have for solving #270 . `rust-semverver` is not perfect, but it can deal with functions, consts, and simple structs just fine, and that's pretty much everything that libc uses.

Some other notes:
* we have to compile `rust-semverver` for each toolchain version, and it depends on `cargo` so we have to build ~160 dependencies. Using `cache: cargo` breaks everything.
Add arm-uclibc definitions
I used `buildroot-2017.05` to build armv7 cross compiler, `uclibc-1.0.24` and `libc-test`. I've executed `libc-test` on armv7-based SoC, using modified `libc-test` to account for the environment. Modified libc-test is not included in this PR because it is too dependent on cross compilation and execution environment.
cleanup libc-test for OpenBSD
here a cleanup for libc-test for OpenBSD
Some elements (compat for old and now unsupported OpenBSD versions) could be removed, but I think it is better to address them after this PR is merged.
the testsuite for OpenBSD still pass with it (well, with #1280)

openbsd: glob_t recently changed to conform posix (use size_t)
on openbsd, upcoming stable version have changed glob_t definition to follow posix definition (using `size_t` instead of `int` on some fields)
the change preserves bitrig definition
r? @gnzlbg
Implement more extra_traits
Finishing the implementation of rust-lang/rust#57715 now that all platforms are tested in CI. I plan to expand this CI to all platforms that need this treatment (solarish, empscripten, freebsd, and netbsd), but thought I'd get the part I've already started running in CI since I can't test this changes locally.
