clang scan-build is annoyed it's not obvious the sizeof line matches the
pointer type. This is easy to fix and makes it be quiet.

In some cases it would be good to restrict the input range of scalars
given to |EC_METHOD::mul| to be [0, order-1]. This is a first step
towards that goal.

Without |EC_POINTs_mul|, there's never more than one variable point
passed to a |EC_METHOD|'s |mul| method. This allows them to be
simplified considerably. In this commit, the p256-x86_64 implementation
has been simplified to eliminate the heap allocation and looping
related that was previously necessary to deal with the possibility of
there being multiple input points. The other implementations were left
mostly as-is; they should be similarly simplified in the future.

This moves us closer to having |EC_GROUP| and |EC_KEY| being immutable.
The functions are left as no-ops for backward compatibility.

This extends 9f1f04f313 to the other
implementations.
|EC_GFp_nistp224_method| and |EC_GFp_nistp256_method| are not marked
|OPENSSL_EXPORT|. |EC_GROUP_set_generator| doesn't allow the generator
to be changed for any |EC_GROUP| for built-in curves. Consequently,
there's no way (except some kind of terrible abuse) that this code
could be executed with a non-default generator.

If the application is only using the P-256 implementation in p256-64.c,
then the WNAF code would all be dead code. The change reorganizes the
code so that all modern toolchains should be able to recognize that
fact and eliminate the WNAF-based code when it is unused.

None of these methods vary per group. Factoring these out of
|EC_METHOD| should help some toolchains to do a better job optimizing
the code for size.

This change converts the reference counts in crypto/ to use
|CRYPTO_refcount_t|. The reference counts in |X509_PKEY| and |X509_INFO|
were never actually used and so were dropped.
