Merge from gnulib, improving some licensing wording.

* charset.c: Integer overflow fixes.
Don't rely on undefined behavior with signed left shift overflow.
Don't assume unsigned int fits into fixnum, or that fixnum fits
into unsigned int. Don't require max_code to be a valid fixnum;
that's not true for gb10830 4-byte on a 32-bit host. Allow
invalid_code to be a cons, for the same reason. Require code_offset
to be a character. Avoid int overflow if max_char is close
to INT_MAX.
(CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
this is intended anyway and avoids some undefined behavior.
(load_charset_map): Pass unsigned, not int, as 2nd arg of
INDEX_TO_CODE_POINT, as that's what it expects.
