[PATCH 1/2] sim: export cb_get_string for people to use

[Mike Frysinger <vapier@gentoo.org>]

The common sim code provides a useful "get_string" function which reads
a C string out of the target's memory space.  So rename and export it
for other people to use.

	* callback.h (cb_get_string): New prototype.

sim/common/:
2011-05-26  Mike Frysinger  <vapier@gentoo.org>

	* syscall.c (cb_get_string): Rename from "get_string".
	(get_path): Rename get_string call to cb_get_string.
