[Chicken-hackers] srfi-13 %string-copy speedup

Core hackers, consider the attached srfi-13 patch which speeds up %string-copy!
by using an inline C_substring_copy (something that I guess has been noted
and planned for a while).

I saw a 1.5x speedup when concatenating 1 million 1-byte strings and
a 10x speedup for concatenating 15 one-million-byte strings.

Speedwise, this brings string-concatenate up to par with string-append,
without the argument limit.
