Subject: [PATCH] rename yy_scan_string manually

flex 2.6.0 used to generate code where yy_scan_string was mapped
to <custom prefix>_scan_string directly in the generated .c code.

For example, generate/unix/iasl/obj/prparserlex.c:

int
PrInitLexer (
    char                    *String)
{

    LexBuffer = PrParser_scan_string (String);
    return (LexBuffer == NULL);
}

flex 2.6.3 no longer does that, leading to a compiler warning
and link error about yy_scan_string().

Both versions generate a preamble in the beginning of prparserlex.c
that maps several yy_* names, but yy_scan_string is not among those:
