Rename gpio driver file.
Fix typo.
Update the default RSS hash to the Chelsio T5 firmware one - it provides
markedly better distribution of IPv6 address/ports than the previous key.

The previous key would hash large swaths of the port space for a given
source/destination IP address to the same low handful of bits, effectively
mapping them to the same queue.  This made testing very .. special.

Import unblock-lan-zones feature backported from upstream svn trunk.
This is a partial fix for reverse lookups in RFC 1918 networks.  With
this option enabled, unbound no longer ignores these queries; however,
it will still reject the answer it gets from the forwarder, because
the RFC 1918 reverse zones are signed.
