crypto: remove deperecated methods of TLS version

All version-specific methods were deprecated in OpenSSL 1.1.0 and
min/max versions explicitly need to be set.
This still keeps comptatible with JS and OpenSSL-1.0.2 APIs for now.

crypto, constants: add constant of OpenSSL-1.1.0

Several constants for OpenSSL-1.1.0 engine were removed and renamed in
OpenSSL-1.1.0. This added one renamed constant in order to have a
compatible feature with that of OpenSSL-1.0.2.
Other missed or new constants in OpenSSL-1.1.0 are not yet added.

crypto,tls,constants: remove OpenSSL1.0.2 support

This is semver-majar change so that we need not to have
compatibilities with older versions.
