-----------------------------+-----------------------------
 Add Pre/Post hooks to unzip logic, providing groundwork for advanced
 Malware scanning + advanced role management by interacting with OS using
 chattr facility to enforce super admin capabilities, requiring OS level
 authentication prior to taking action on any zipfile contents.

 Logic...

 1) Refactor _unzip_file_pclzip() + _unzip_file_ziparchive() merge into
 single function + merge common code.

 2) Hooks...

 required_disk_space - notify how much additional disk space required
 required_directories - notify list of missing directories, which will be
 created

 pre_unzip - return zipfile path + archive component name if applicable
 post_unzip - return zipfile path + unzip directory + archive component
 name if applicable

 3) Additionally, zipfile source propagation could be highly useful.

 Either local filesystem reference or download URL.
