Use the output buffer as a temporary buffer to store clamped private scalars
...
This might help avoid leaving a copy of the scalar on the stack.
Also use the same parameters names in donna as other implementations.
Maybe not the best possible names, but at least, things are consistent.

Return -1 is the scalar was zero
...
This realistically only happen on misuse or with a completely broken PRG.
Calling misuse() would be a bit too intrusive here. So, we still store
the result (might be better than uninitialized memory if the application
doesn't check the return code), but return -1.

Move a couple functions from crypto_sign to crypto_core/curve25519

This improves clarity and makes it easier to reuse these in a
different context.
Also change fe_isnonzero() to fe_zero() and make it work as
documented.
