Add a new interface, OPENSSL_cpu_caps(), to return the currently running

cpu's specific hardware capabilities users of libcrypto might be interested
in, as an integer value. This deprecates the existing OPENSSL_ia32cap()
macro and the OPENSSL_ia32cap_loc() function (which returns the pointer so
that you can mess with stuff you shouldn't mess with).

Interpreting the value returned by OPENSSL_cpu_caps() is, of course,
machine-dependent.

Minor version bump for libcrypto.
