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.

/* The purpose of this file is so that there is at least one actual
   definition of each inline function.  This is needed under GCC.  The
   reason is that under GCC we declare our inline functions `inline
   extern', which causes the inlined version to get used only for
   inlining, and in other cases to generate an external reference to
   the function.  This is more efficient than declaring our inline
   functions `inline static', which (in many cases) would cause a separate
   version of the function to get inserted into every source file that
   included the corresponding header file.  See internals.texi.

   Some compilers that recognize `inline' may not do the same
   `inline extern' business, so on those we just do `inline static'.

/* Note to maintainers: This file contains a list of all header files
   that use the INLINE macro, either directly, or by using DECLARE_LISP_OBJECT.
   i.e. the output of ``grep -l -w 'DECLARE_LISP_OBJECT|INLINE_HEADER' *.h'' */

/* If we demand !defined (HAVE_SHLIB) the INLINE_HEADERS aren't instantiated.
   This only shows up in --with-error-checking=types builds AFAIK.
   On Mac OS X 10.3.9 with the Apple toolchain (GCC 3.3) gives a buildtime
   link error (the lrecord error_check functions are undefined).
   Debian GNU/Linux `sid' with GCC 4.0.3 prerelease & binutils 2.16.91 gives
   a runtime link error (the lrecord error_check functions are undefined).
   It is possible that this can be fixed trickily by appropriately defining
   INLINE, or that it should be done in the module itself somehow.  If you
   can do it better or more elegantly, please feel free to consult me.
