Add a 'core' library alongside 'common'.

Browse Source 
The 'core' library contains almost all the same objects as 'common',
but leaves out hat.c. And the auxiliary program 'hatgen' now links
against that slightly reduced core library instead of 'common'.

This avoids a dependency loop: one of hatgen's jobs is to generate
hat-tables.h, but hat-tables.h is a dependency of it.

Of course, the generated hat-tables.h is already committed, so this
doesn't present a bootstrapping problem in a normal build. But if
someone modifies hatgen.c in order to regenerate hat-tables.h, and
does so in a way that makes it uncompilable, they can't rebuild hatgen
and try again! Of course you can always revert changes with git, but
it's annoying to have to. Better to keep the dependencies non-cyclic
in the first place.
