Prior to this commit some helper scripts used hardcoded paths to
`/bin/sh` and `/bin/bash` in script shebangs. This will error on systems
that don't place `bash` in `/bin/` (e.g. NixOS).
This commit updates the scripts to use `/usr/bin/env` to find `bash`
based on the user's `$PATH`. This has better portability and allows the
scripts to run without err (or specifying an interpreter explicitly) on
systems with atypical `bash` installs.
Make it easier to find the {Client,Server}CertVerifier tests. Split
them into separate files so that we can use `diff` to compare how we're
testing each.
This removes all of the `dangerous_configuration` tests from tests/api.rs.
Each of the mock Client/Server verifiers were eached move into the single test
suite that uses it.
Use these commands with a whitespace-smart diff tool to see that the tests
were not modified except for whitespace and formatting:
```
git difftool HEAD^1:rustls/tests/api.rs rustls/tests/server_cert_verifier.rs
git difftool HEAD^1:rustls/tests/api.rs rustls/tests/client_cert_verifier.rs
git difftool HEAD^1:rustls/tests/common/mod.rs rustls/tests/client_cert_verifier.rs
git difftool HEAD^1:rustls/tests/common/mod.rs rustls/tests/server_cert_verifier.rs
```
Serialize all tests that use `std::env::set_var` & isolate them. See the
comments in key_log_file_env.rs for details.
Also add notes about the fact that these tests aren't really testing the
functionality.
Use a whitespace-smart diff tool to compare the new file to what was in
api.rs:
```
git difftool HEAD^1:rustls/tests/api.rs rustls/tests/key_log_file_env.rs
```
Upstream removed -Zno-landing-pads; unfortunately there's still
no better coverage tooling.
Fortunately -Cpanic=abort is now feasible for tests thanks to
-Zpanic-abort-tests.
- rustls (the library) now lives in rustls/
- the mio examples/tests continue to live in rustls-mio, but
are built by (eg) `cargo test` in the root of the repo.
