Separate result area for ecc_mod_mul and ecc_mod_sqr.
* ecc-mod-arith.c (ecc_mod_mul, ecc_mod_sqr): Separate argument
for scratch area, reducing required size of result area. Update
all callers to naïvely keep using result in scratch area.
(ecc_mod_pow_2k, ecc_mod_pow_2k_mul): Simplified, also reducing
required size of result area.
