    Conditionalise the inclusion of config.h.

    Since autoconf helpfully tells us it exists, we shouldn't try to
    include it if it hasn't told us so.

    Centralise the inclusion of bigint.h.

    Since it's a dependency of spigot.h, spigot.h can include it itself,
    and then every other module doesn't have to.

    Rename bigint.h to bi_gmp.h.

    In preparation for it no longer being the only bigint provider.

    Provide our own bigint implementation.

    This is a trivial implementation, with not much optimisation -
    multiplication is by the entirely naive quadratic algorithm. But it's
    good enough to generate 10,000 digits of pi in just over 4x the time
    GMP takes, and run 'make test' in 3x the time.

    GMP is still selected if autoconf can find it, but is now no longer a
    hard dependency - we can fall back to this implementation if GMP is
    unavailable, which should make it easier to build and run on Windows.

    Stop calling member functions 'putchar'.

    It goes horribly wrong if that's defined as an interesting macro in
    stdio.h.

    Add precautionary casts and != 0.

    Visual Studio seems prone to getting confused between ints and bools,
    so let's help it along.

    Cope with Visual Studio's deficient snprintf.

    Now I've actually been able to build spigot on Windows, using VS2010
    with the compile command 'cl /EHsc /Fespigot.exe *.cpp'. (/EHsc
    enables C++ exceptions, which are off by default in Visual Studio.)
