rename misc2.c to core.c

The remaining functions in misc2.c are "fundamental" ones relating
to, for instance, writing bytes and times. At this point, it makes
more sense to simply rename misc2.c to better reflect the "core"
functionality that the functions contained within implement,
hence "core.c".
rename core.c to fundamental.c

The rename to core.c seems to make the compiler mistake the
generated files as core dumps, which results in compile failure.
This commit is being made to test that theory.
