6d6c8287d5 Include __mulodi4 in libor_ctime when it fixes clang -m32 -ftrapv 
We use a pretty specific pair of autoconf tests here to make sure
that we only add this code when:
   a) a 64-bit signed multiply fails to link,
 AND
   b) the same 64-bit signed multiply DOES link correctly when
      __mulodi4 is defined.

Closes ticket 19079.

33034600c2 Add __mulodi4 source to src/ext 
We need to define this function when compiling with clang -m32 -ftrapv,
since otherwise we get link errors, since apparently some versions
of libclang_rt.builtins don't define a version of it that works? Or
clang doesn't know to look for it?

This definition is taken from the LLVM source at
  https://llvm.org/svn/llvm-project/compiler-rt/trunk/lib/builtins/mulodi4.c

I've also included the license (dual BSD-ish/MIT-ish).

00f74e0372 Improve API of routerinfo_incompatible_with_extrainfo() 
This API change makes it so that routerinfo_incompatible...() no
longer takes a routerinfo_t, so that it's obvious that it should
only look at fields from the signed_descriptor_t.

This change should prevent a recurrence of #17150.

49ff09aef2 Fix another, more subtle, case of bug 17150. 
We need to make sure that the corresponding sd and ei match in their
certificates.

8acfac7375 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.

This patch fixes no actual behavior.

7d1eb0d570 When making sure digest256 matches in ei, look at sd, not ri. 
The routerinfo we pass to routerinfo_incompatible_with_extrainfo is
the latest routerinfo for the relay.  The signed_descriptor_t, on
the other hand, is the signed_descriptor_t that corresponds to the
extrainfo.  That means we should be checking the digest256 match
with that signed_descriptor_t, not with the routerinfo.

Fixes bug 17150 (and 19017); bugfix on 0.2.7.2-alpha.

44da47d3c1 Move extra_info_digest256 into signed_descriptor_t 
This patch includes no semantic changes; it's just a field movement.

It's prerequisite for a fix to 19017/17150.
