c521e4392f ec/curve25519.c: facilitate assembly implementations. 
Currently it's limited to 64-bit platforms only as minimum radix
expected in assembly is 2^51.

127d6cf747 crypto/ec/curve25519.c: remove redundant fe[51]_cswap. 
3 least significant bits of the input scalar are explicitly cleared,
hence swap variable has fixed value [of zero] upon exit from the loop.

9c9d6ff41c Simplify some code 
The original curve448 code was templated to allow for a 25519
implementation. We've just imported the 448 stuff - but a remnant of
the original templated approach remained. This just simplifies that.

2abe3cad23 Remove the curve448 vector code 
We removed various platform specific optimisation files in an earlier
commit. The vector code was related to that and therefore is no longer
required. It may be resurrected at a later point if we reintroduce the
opimtisations.
