Improve digit counting for multibulk creation

This replaces the old intlen() implementation with a slightly
faster way of counting digits.

Implementation taken from the same place where digits10() in
redis/src/util.c came from.

The old 'intlen' allowed negative inputs, but no usage in hiredis
was passing negative numbers, so that ability is removed.  Also,
the new implementation can count higher (uint64_t) instead of
limited to just int as before.

Fixes #295 by replacing implementation
