This CL provides the rest of the SetCookies code as well as
some test infrastructure which will be used to test also
the Cookies method. This test infrastructure is optimized
for readability and tries to make it easy to review table
driven test cases.

Tests for all the different corner cases of SetCookies
will be provided in a separate CL.

The spec is not clear about whether this is allowed or not,
but both compilers allow it, because the reflect implementation
takes advantage of it. Document current behavior.

Add benchmarks for common http benchmarking tools. The intent is to catch optimisations which favor synthetic benchmarks that do not show improvements for real clients like Chrome.

this is a little non-deterministic, this change disables that test

By default, crypto/x509 assumes that users wish to validate
certificates for ServerAuth. However, due to historical reasons,
COMODO's intermediates don't specify ServerAuth as an allowed key
usage.

Rather NSS and CryptoAPI both allow these SGC OIDs to be equivalent to
ServerAuth.

It might be non-blocking, but it also might be blocking.
Cannot take the chance, as Accept might block indefinitely
and make it impossible to acquire ForkLock exclusively
