Add <opensslfeatures.h> to ease migration from OpenSSL.
The <opensslfeatures.h> header provides #defines which are normally
declared by OpenSSL when features are disabled.
This way applications are able to detect which features were removed
from BoringSSL and use it as drop-in replacement for OpenSSL.
Inspired by LibreSSL, which provides similar header.
