4b76fe8036 Break DirFetchPostPeriod into: 
- DirFetchPeriod for fetching full directory,
  - StatusFetchPeriod for fetching running-routers,
  - DirPostPeriod for posting server descriptor,
  - RendPostPeriod for posting hidden service descriptors.

Also make sure the hidden service descriptors are at a random
offset from each other, to hinder linkability.

57536f138a Fetch running-routers. 
Split logic to initiate dirfetch, running-routers fetch, and
descriptor post.  arma: There are some XXXs here that raise design
questions which we should solve before the next release.

The biggest problem is this: Right now, the directory is about 50X as
large as running-routers uncompressed, and about 36X as large
compressed.  Assuming:

    - everybody gets the compressed version of everything,

    - everybody gets cached directories from random dirservers and
      uncached r-r from authdirservers

    - everybody downloads r-r at the same rate they now download dirs,

then using r-r from will *increase* authdirserver directory bandwidth usage
if there are significantly more caches than authdirservers.

I think it's safe to leave this in for now, since there aren't 3x36 caching
dirservers, but we should make everybody with a dirport cache running-routers
soon.  But I could be wrong.

d381aa4696 Fix an evil bug: when we failed to write to our log, fputs() 
gave us a sigpipe, and we logged that we were ignoring it,
causing us to fail to log that, and delete the log entry. Then
when the signal handler exited, we proceeded to delete the log
entry that had already been deleted.

Now we make sure to only log inside our signal handler if we'll
be exit()ing right after.

- make clients cache directories and use them to seed their router lists
   at startup.  This means clients have a datadir again.
 - Introduce a global_write_bucket.  We need to respond better to exhausting
   it.
 - Remove the last vestiges of LinkPadding and TrafficShaping.
 - Configuration infrastructure support for warning on obsolete options.
 - Refactor directory header parsing to use smartlist_split_string.
 - Respond to content-encoding headers by trying to uncompress as appropriate.
 - Reply with a deflated directory when a client asks for "dir.z".
