Optimize main loop in find_bytestr()
The only reason for keeping the "remain" variable a hed_off_t is that
it the 0..SIZE_MAX range is used for forward searches and -SIZE_MAX..0
is used for backward searches. For all practical purposes, the segment
size can be limited to SSIZE_MAX. This allows me to use ssize_t instead,
which performs better on 32-bit architectures.
As a bonus, I can use move_rel_fast() for the final cursor move.
