directories on disk. Make authdirservers cache *their own*
directories instead of the ones they download. This gives better
liveness, and marginally better resistance to broken authdirservers.
Authdirservers don't cache running-routers at all: r-r isn't stored to
disk, so there's no point right now.

they weren't writing anything into their datadirectory, so
when they stop and start, they would know nothing until they
fetched a directory from another authdirserver.

- 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.

the right thing with our recalcitrant versioning scheme. See
tor.spec.in for full details. Basically, the progression is now:
Tor version RPM version
0.0.8 ---> 0.0.8
0.0.8.1 ---> 0.0.8.1
0.0.9pre1-cvs ---> 0.0.8.99.0.0.9.pre.1.cvs
0.0.9pre1 ---> 0.0.8.99.0.0.9.pre.1.release
0.0.9pre2 ---> 0.0.8.99.0.0.9.pre.2.release
0.0.9rc1 ---> 0.0.8.99.0.0.9.rc.1.release
0.0.9 ---> 0.0.9
0.0.9.1-cvs ---> 0.0.9.0.99.0.0.9.1.cvs
0.0.9.1 ---> 0.0.9.1
The spec file (but not the system) will break if a tor version ends in
".0", so don't do that yet.

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.
