checkpoint on string realloc bug fix attempt

Browse Source 
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.
