Convert C (un)signed long long values to bignums properly.
This patch also does the following:
- Uses make_fixnum instead of make_integer when the argument is guaranteed to
be in the fixnum range.
- Introduces make_unsigned_integer so that we handle unsigned values with the
high bit set correctly.
- Introduces conversions between bignums and (un)signed long long values.
- Uses mp_set_memory_functions with the BSD MP code, if it exists.
- Eliminates some unnecessary consing in the Lisp + and * implementations.
- Fixes a problem with check_valid_xbm_inline(). This function is called
during intialization. It calls Ftimes. When using pdump, this is a
problem, because (a) the bignum code is not initialized until *after*
dumping, so we don't try to dump any bignums, and (b) multiplication of
integers is done inside bignums so we handle fixnum overflow correctly. I
decided that an XBM file with dimensions that don't fit into fixnums is
probably not something we want to try to handle anyway, and did the
arithmetic with C values instead of Lisp values. Doing that broke one test,
which started getting a different error message from the one it expected, so
I adjusted the test to match the new reality.
- Fixes a few miscellaneous bugs in the BSD MP code.
