Support for calculating MAC (message authentication code) on encrypted
data instead of plain text data.
This adds support for the following MACs:
- `hmac-sha1-etm@openssh.com`
- `hmac-sha2-256-etm@openssh.com`
- `hmac-sha2-512-etm@openssh.com`

- rename tests to have more succint names and a more useful natural
order.
- rename `simple` and `ssh2` in tests to have the `test_` prefix.
This avoids a name collisions with `ssh2` in examples.
- cmake: drop the `example-` prefix for generated examples.
Bringing their names in sync with other build tools, like autotools.
- move common auth test code into the fixture and simplify tests by
using that.
- move feature guards from CMake to preprocessor for auth tests.
Now it works with all build tools and it's easier to keep it in sync
with the lib itself.
For this we need to include `libssh2_priv.h` in tests, which in turn
needs tweaking on the trick we use to suppress extra MSVS warnings
when building tests and examples.
- move mbedTLS blocklist for crypto tests from CMake to the test
fixture.
- add ed25519 hostkey tests to `test_hostkey` and `test_hostkey_hash`.
- add shell script to regenerate all test keys used for our tests.
- alpha-sort tests.
- rename `signed_*` keys to begin with `key` like the rest of the keys
do.
- whitespace fixes.
Closes#969
