[tor/release-0.2.8] Copy the signing_key_cert field into signed_descriptor_t

commit 8acfac7375e7a0692193434704984d7eb507faf1 Author: Nick Mathewson <nickm(a)torproject.org> Date: Tue May 17 13:14:04 2016 -0400 Copy the signing_key_cert field into signed_descriptor_t We need this field to be in signed_descriptor_t so that routerinfo_incompatible_with_extrainfo can work correctly (#17150). But I don't want to move it completely in this patch, since a great deal of the code that messes with it has been in flux since 0.2.7, when this ticket was opened. I should open another ticket about removing the field from routerinfo_t and extrainfo_t later on.

[tor/release-0.2.8] When making sure digest256 matches in ei, look at sd, not ri.

commit 7d1eb0d57086c9630f7797916d9d2c948117a7e1 Author: Nick Mathewson <nickm(a)torproject.org> Date: Tue May 17 12:57:03 2016 -0400 When making sure digest256 matches in ei, look at sd, not ri.
