synopsis

	 char *

	 char s[];

description

	savestr(s) returns a pointer to a newly-allocated block of memory
	containing a copy of s.  The memory is obtained from malloc() and
	should be freed with free() when you are done with it.

	savestr() returns NULL if it cannot obtain the memory it needs.
