Drop all options except thread safety. Also remove InitializerOptions, etc

and reduce all the arguments to just a bool specifying threads.

selftests: off (if desired, run passes_self_test in selftest.h)

fips140: Just ran the self tests, totally bogus option.

use_engine: On by default (that is, if OpenSSL or asm code is compiled
in, it's used by default). One can get better control over this using
the provider feature of SCAN_Name (though this doesn't handle cases like
nested algorithms yet).

secure_memory: On by default.
