Subject: [PATCH v1] Miscellaneous little fixes

- Fix two "fist" typos in comments in hyperloglog.c and indxpath.c.
- Fix incorrect IPv6 address width in a comment in network.c: IPv6  addresses
  are 128 bits, not 64.
- Remove the oid_hash macro from hashfn.h. The last real caller was removed
  in commit 4a14f13a0ab in December 2014, which also added the "Remove me
  eventually" notice.
