remove deprecated modules

[narimiran]

These modules were deprecated either 3 (since version 0.11.x) or 4 (since version 0.10.x) years ago.

---

EDIT after I pushed "further removals and deprecations", here are some more details:

• 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)
