Add some GCC warnings to the standard set, and add some others to the

--enable-extra-gcc-checks set.

If we turn on -pedantic, try turning on -Wno-long-long as well, so that
it's not *so* pedantic that it rejects the 64-bit integral data types
that we explicitly require.

Constify a bunch of stuff, and make some other changes, to get rid of
warnings.

Clean up some indentation.
