There are three reasons we use a cached_dir_t to hold a consensus:
1. to serve that consensus to a client
2. to apply a consensus diff to an existing consensus
3. to send the consensus to a controller.
But case 1 is dircache-only. Case 2 and case 3 both fall back to
networkstatus_read_cached_consensus(). So there's no reason for us
to store this as a client. Avoiding this saves about 23% of our RAM
usage, according to our experiments last month.
This is, semantically, a partial revert of e5c608e535.
Fixes bug 27247; bugfix on 0.3.0.1-alpha.

o Minor bugfixes (client, memory usage):
|
|
- When not running as a directory cache, there is no need to store the
|
|
text of the current consensus networkstatus in RAM. Previously,
|
|
however, clients would store this anyway, at a cost of over 5 MB.
|
|
Now, they do not. Fixes bug 27247; bugfix on 0.3.0.1-alpha.
