Fix compiler warnings about string overflows in prom_parse

Gcc compiler version 7.2.1 complains about possible string
overflow from prom_parse.y:

> prom_parse.tab.c: In function ‘yyparse’:
> prom_parse.y:98:25: warning: ‘%s’ directive writing up to 255 bytes into a region of size between 0 and 255 [-Wformat-overflow=]
>     sprintf($$, "%s/%s", $<str>1, $<str>3);
>                          ^~~~~~~

So make the string buffer larger. Also, tell the compiler it is
ok if we truncate strings, since our buffer is very large. Lastly,
ensure we use strncpy() when copying strings.

+       that there is no unexpected or expected token to report.  In that

+     - Don't assume there isn't a lookahead just because this state is a
+       consistent state with a default action.  There might have been a
+       previous inconsistent state, consistent state with a non-default
+       action, or user semantic action that manipulated yychar.
+     - Of course, the expected token list depends on states to have
+       correct lookahead information, and it depends on the parser not
+       to perform extra reductions after fetching a lookahead from the
+       scanner and before detecting a syntax error.  Thus, state merging
+       (from LALR or IELR) and default reductions corrupt the expected
+       token list.  However, the list is correct for canonical LR with
