In preparation to fix issue #47, we: Fix a minor typo in `Makefile.config`. Move `stringindex(char *format, char *test)` from `str.c` into `codegen.c` as static function. Expand `STR_TABLECHUNK` from `1<<10` to `1<<16`. Identify with an XXX comment, a problematic `realloc()` call in the `addstr(STRINGHEAD *hp, char *str)` function of `str.c`. Move the `charstr(int ch)` in `str.c` above the only function that uses it, `addliteral(char *str)`, and make it a static function. Improved comments about return values for `str.c` functions that work on STRINGHEAD pointers.
