shill: Renames Config80211 to NetlinkManager.

The domain of Config80211 has extended to different types of netlink
message communication.  That warrants a name change.  This CL changes
the name of the class plus a bunch of objects of that class.  This
required changing the names of some files.

In addition, a few (half a dozen, maybe) readability issues were
addressed.  These include inaccurate header guard comments and bad
indentation.

BUG=None
TEST=unittest
