Always require a 64 bit integer type

* configure.ac (available_digests_64): Merge with available_digests.
(available_kdfs_64): Merge with available_kdfs.
<64 bit datatype test>: Bail out if no such type is available.
* src/types.h: Emit #error if no u64 can be defined.
(PROPERLY_ALIGNED_TYPE): Always add u64 type.
* cipher/bithelp.h: Remove all code paths which handle the
case of !HAVE_U64_TYPEDEF.
* cipher/bufhelp.h: Ditto.

Given that SHA-2 and some other algorithms require a 64 bit type it
does not make anymore sense to conditionally compile some part when
the platform does not provide such a type.
