Re-write t_agetstr() so that it does not use realloc so userland programs don't break. We now use an internal buffer to keep track of the memory we allocate. This changes the api of t_agetstr() to take 2 fewer arguments, but there are not many programs that use it. Please note that this does not change binary compatibility with the previous t_agetstr() since the usage was: char *area, *p; *area = NULL; t_agetstr(ti, "ic", &area, &p); ... free(area); Since we don't touch the arguments and free(NULL) is a no-op, nothing breaks. Since we don't break binary compatibility there is no reason to bump the library's major number, but since we change t_agetstr() I'll bump the minor number for good measure.
