Import netatalk30-3.0.8 as wip/netatalk30.

Netatalk 3 is a freely-available implementation of the Apple
Filesharing Protocol Suite (AFP) over TCP/IP.

Using Netatalk's AFP 3.1 compliant file-server leads to significantly
higher transmissions speeds compared with Macs accessing a server via
SMB or NFS, while providing clients with the best user experience (full
support for Macintosh metadata, flawlessly supporting mixed
environments of classic MacOS and MacOS X clients).
Add netatalk30 which packages Netatalk 3.0.8.

Netatalk ships two supported releases, currently 3.0.x and 3.1.x.

Note that this package does not supersede net/netatalk, which is the
last version supporting ddp based AppleTalk, and should be renamed
netatalk2 or netatalk-ddp once netatalk30 is imported.
