Need a string_unescape function returning c-string

[kjstol]

hi,
Parrot has a string_unescape_cstring function, which is fine, but returns a
STRING * object.

However, I (well, PIRC does) need a string unescape function (taking a
c-string) that returns a c-string.

Can we add a function to string.c that does in fact just that, and let
string_unescape_cstring() invoke that, and convert the result into a STRING
*?
