Replace implicit doc compression with dir compression in old EAPIs

Unify the documentation compression methods in all EAPIs to compress
per-directory rather than implicitly compress files installed by dodoc,
doinfo and doman. Old EAPIs don't provide docompress to control which
directories are compressed but they don't say anything about dodoc etc.
compressing anything either.
