1.8-3 RC 2

prepare for CRAN submission

* fix bug 2227
* local tests
* remove warnings from pkgdown::build_site()
* update.packages() and then run revdepcheck
* run remote tests as in check_package.R, skipping rhub which is broken
  owing to a problem with building ncdf that goes back to early in the
  year, and unrelated to oce.
