05dee063c8 Emit router families in canonical form 
This patch has routers use the same canonicalization logic as
authorities when encoding their family lists.  Additionally, they
now warn if any router in their list is given by nickname, since
that's error-prone.

This patch also adds some long-overdue tests for family formatting.

0a0c612b79 Add a consensus method in which md families get canonicalized. 
Implements prop298. Closes ticket 28266.

d29e3a02d5 Add a function to canonicalize nodefamilies per prop298 
This is the same as the regular canonical nodefamily format, except
that unrecognized elements are preserved.

0e9a963b6b Revise nodefamily.c to match proposal 298 
Prop298 says that family entries should be formatted with
$hexids in uppercase, nicknames in lower case, $hexid~names
truncated, and everything sorted lexically.  These changes implement
that ordering for nodefamily.c.

We don't _strictly speaking_ need to nodefamily.c formatting use
this for prop298 microdesc generation, but it seems silly to have
two separate canonicalization algorithms.

83be4d2bbd Backend for compact node-family representation. 
This representation is meant to save memory in microdescriptors --
we can't use it in routerinfo_t yet, since those families need to be
encoded losslessly for directory voting to work.

This representation saves memory in three ways:
   1. It uses only one allocation per family.  (The old way used a
      smartlist (2 allocs) plus one strdup per entry.)
   2. It stores identity digests in binary, not hex.
   3. It keeps families in a canonical format, memoizes, and
      reference-counts them.

Part of #27359.

b9a88bd53a Add new "ALL" and "NET_PARTICIPANT" roles for periodic events 
The previous "ALL" role was the OR of a bunch of other roles,
which is a mistake: it's better if "ALL" means "all".

The "NET_PARTICIPANT" role refers to the anything that is actively
building circuits, downloading directory information, and
participating in the Tor network.  For now, it is set to
!net_is_disabled(), but we're going to use it to implement a new
"extra dormant mode".

Closes ticket 28336.
