rollup merge of #21754: semarie/openbsd-rebased

Hi.

Here a commit in order to add OpenBSD support to rust.

- tests status:
run-pass: test result: ok. 1879 passed; 0 failed; 24 ignored; 0 measured
run-fail: test result: ok. 81 passed; 0 failed; 5 ignored; 0 measured
compile-fail: test result: ok. 1634 passed; 0 failed; 22 ignored; 0 measured
run-pass-fulldeps: test result: ok. 22 passed; 0 failed; 1 ignored; 0 measured
compile-fail-fulldeps: test result: ok. 13 passed; 0 failed; 0 ignored; 0 measured

- The current implementation of load_self function (src/libstd/sys/unix/os.rs) isn't optimal as under OpenBSD I haven't found a reliable method to get the filename of a running process. The current implementation is enought for bootstrapping purpose.

- I have disable `run-pass/tcp-stress.rs` test under openbsd. When run manually, the test pass, but when run under `compiletest`, it timeout and echo continuoulsy `Too many open files`.

- For building with jemalloc, a more recent version of jemalloc would be mandatory. See https://github.com/jemalloc/jemalloc/pull/188 for more details.
