qtest: pre-buffer hex nibs

Instead of converting each byte one-at-a-time and then sending each byte
over the wire, use sprintf() to pre-compute all of the hex nibs into a
single buffer, then send the entire buffer all at once.

This gives a moderate speed boost to memread() and memwrite() functions.
