include: Drop <common.h> from include lists

At this point, we don't need to have <common.h> be included because of
properties in the header itself, it only includes other common header
files. We've also audited the code enough at this point that we can drop
<common.h> from being included in headers and rely on code to have the
correct inclusions themselves, or at least <common.h>.
