This commit implements a new config option: 'DisableAllSwap'
This option probably only works properly when Tor is started as root.
We added two new functions: tor_mlockall() and tor_set_max_memlock().
tor_mlockall() attempts to mlock() all current and all future memory pages.
For tor_mlockall() to work properly we set the process rlimits for memory to
RLIM_INFINITY (and beyond) inside of tor_set_max_memlock().
We behave differently from mlockall() by only allowing tor_mlockall() to be
called one single time. All other calls will result in a return code of 1.
It is not possible to change DisableAllSwap while running.
A sample configuration item was added to the torrc.complete.in config file.
A new item in the man page for DisableAllSwap was added.
Thanks to Moxie Marlinspike and Chris Palmer for their feedback on this patch.
Please note that we make no guarantees about the quality of your OS and its
mlock/mlockall implementation. It is possible that this will do nothing at all.
It is also possible that you can ulimit the mlock properties of a given user
such that root is not required. This has not been extensively tested and is
unsupported. I have included some comments for possible ways we can handle
this on win32.
This new option will allow clients to download the newest fresh consensus
much sooner than they normally would do so, even if they previously set
FetchDirInfoEarly. This includes a proper ChangeLog entry and an updated man
page.
Added a sanity check in config.c and a check in directory.c
directory_initiate_command_rend() to catch any direct connection attempts
when a socks proxy is configured.
PublishServerDescriptor 1 means "publish to the relevant authority", not "publish to v2,v3 authorities". Also adjust the time in the manpage to January 2009

(Many users have no idea what a resolv.conf is, and shouldn't be forced to learn. The old option will keep working for now.)
Also, document it.

rejected them in 0.1.0.15, because back in 2005 they were commonly
misconfigured and ended up as spam targets. We hear they are better
locked down these days.

Patch from Christian Wilms: remove (HiddenService|Rend)(Exclude)?Nodes options. They never worked properly, and nobody seems to be using them. Resolves bug 754.

Add new ExcludeExitNodes option. Also add a new routerset type to handle Exclude[Exit]Nodes. It is optimized for O(1) membership tests, so as to make choosing a random router run in O(N_routers) time instead of in O(N_routers*N_Excluded_Routers).
