build: add OpenSSL-1.1.0 support

- For Windows, nasm is new build requirements and openssl_no_asm is
  set to 1 with warning if it is not installed.
- For use of openssl assemble codes, either gas_version >= 2.23,
  xcode_version >= 5.0 ,llvm_version >= 3.3 or nasm_version >= 2.10 is
  needed. Otherwise, openssl_no_asm is set to 1 with warning.
- FIPS is not supported in OpenSSL-1.1.0 so that it leads an error
  when openssl_fips options is enabled in configure.
