Track when we get 503s from directory servers. Do not use directory servers that have given us a 503 until either an hour has passed, or we are are out of non-busy servers.

Add an orport option to dirserver lines so that clients can tell where to connect to open an encrypted tunnel to a dirserver even before they have its descriptor.
svn:r9171
fix a rare memory leak if something goes wrong while rebuilding it,
and clean up some code. nick, please confirm.

Add unit tests for tor_mmap_file(); make tor_mmap_t.size always be the size of the file (not the size of the mapping); add an extra argument to read_file_to_str() so it can return the size of the result string.
svn:r8762
Never discard a descriptor for being too old until either it is recommended by no authorities, or until we download a better (more recent and recommended) one for the same router. This will eventually make it possible for servers to publish less often.
svn:r8761
Change to BadExit logic: Let authorities set an "I list bad exits" flag. Consider an exit bad if it is listed as bad by more than half of *those* authorities. This gives us a better migration path.
svn:r8756
Add client support for a 'BadExit' flag, so authorities can say "Server X is a poor choise for your nytimes.com connections, as it seems to direct them to HoorayForMao.com or (more likely) WouldYouLikeToBuyTheseFineEncyclopedias.com"
svn:r8690
Partial implementation of revised nickname syntax for controllers. Implement ability to look up routers by "verbose" nicknames; add a per-v1-control-connection flag to turn the feature on in events. Needs testing, spec, ability to actually turn on the flag, double-checking that we wont overflow any nickname buffers, and changelog.
svn:r8582
Disprefer exit nodes for entry, middle positions (fixes bug 200). Also, switch to using a uint64_t to hold "total bandwidth for all nodes" under consideration; crypt_rand_int would have died at 2GB/s network capacity.
svn:r8571
Reserve the nickname "Unnamed" for routers that can't pick a hostname; any
router can call itself Unnamed; directory servers will never allocate Unnamed
to any particular router; clients won't believe that any router is the
canonical Unnamed.
svn:r8529
Make "is a v1 authority", "is a v2 authority", and "is a hidden service authority" into separate flags so we can eventually migrate more trust away from moria.
svn:r8523
Refactor entry guard status logic a lot; allow more factors [like not
having a Guard flag or being listed in ExcludeNodes] to render a guard
"unlisted" (now called "unusable"); track guard down status (now
called "unreachable") separately from is_running.
svn:r8519
router_set_networkstatus() gets a list of status documents we asked for from
connection_dir_client_reached_eof(). However, as a cache we (sometimes?) just
ask for "all". router_set_networkstatus() would freak out over that, meaning
it would log a warning and drop the status document instead of caching it
as it is supposed to. Now we let router_set_networkstatus() know if the
data comes from an all-request so it can do the right thing.
svn:r8398
Only do the expensive version of router_have_minimum_dir_info() when the dir info has changed. Backport candidate, since oprofile suggests that this function and ones it calls account for 25-35% of oprofile samples.
svn:r7062
Refactor connection_t into edge, or, dir, control, and base subtypes. This might save some RAM on busy exit servers, but really matters most in terms of correctness.
