remove deprecated modules (#10215)

* removed from `compiler`:
    * lists (deprecated 2 years ago)

* removed from `lib` (all deprecated 3 years ago):
    * ssl
    * matchers
    * httpserver

* removed from `lib/deprecated`:
    * unsigned
    * actors (and three accompanying tests)
    * parseurl

* moved to `lib/deprecated`:
    * securehash (the reason for not directly removing - it was deprecated (only) one year ago)
