remove cbits/directory.c file

[hvr]

or more generally rethink how to handle the cbits in future, they seem kinda redundant by now

this includes figuring out if there's anyone depending on the .h files that may break...

I posted about this in the past but got no responses or complaints.

I think they can be replaced with hsc2hs.

Would removing them require bumping the major version?

[hvr]

IMHO even hsc2hs is overkill here, just plain CapiFFI would probably suffice

Wouldn't that require dropping support for GHC 7.4?

No. Evidence: unix makes extensive use of CapiFFI and works with GHC 7.4 :-)

Oh oops, I saw it in the release notes for 7.6 and thought it was introduced then.

[hvr]

@Rufflewind yeah, that's been a cause of common confusion. There's quite a few who came to believe that CapiFFI excludes GHC 7.4

[Rufflewind]

Based on a few Google searches, I don't think anyone uses the header or any of its functions, so I'll remove them and bump only the minor version.

(I also forgot that I had already removed the dependence on the C bits in the library code, so all I have to do now is to actually delete them.)
