no diea what thta code was actually supposed to achieve

update copyrights and other minor stuff to deliantra

major changes:

- on_same_map and related functions now do not block on map loads, instead
  they pretend the map is not there. this ensures lag-free operation, but changes
  semantics considerably: running quickly over the worldmap often lets you bump
  into map borders until the map has been loaded. also, rabies takes longer
  to nuke a full continent now.
- mapinfo (a major sync blocker) is now fully asynchronous, and works by
  quieing all mapinfo requests and retrying them on every tick until satisfed.

- upgrade crossfire trt to the GPL version 3 (hopefully correctly).
- add a single file covered by the GNU Affero General Public License
  (which is not yet released, so I used the current draft, which is
  legally a bit wavy, but its likely better than nothing as it expresses
  direct intent by the authors, and we can upgrade as soon as it has been
  released).
  * this should ensure availability of source code for the server at least
    and hopefully also archetypes and maps even when modified versions
    are not being distributed, in accordance of section 13 of the agplv3.

- introduce global NOW variable storing current tick time.
- force some packet send at least every 2 seconds, forcing
  an ack reply.
- timeout connections on ack delay exclusively, by default disconnect
  after 8 seconds (allowing for at least 5.5s of network hiccups).
  (linux only, should port to bsds).
- nuke ericserver stats code.
- reduce number of syscalls (less gettimeofday, only get tcp_info
  about once/second).
- get rid of coroapi.time () in favour of now ().

fix longstanding refcnt bug: socket was zereoing wrong flags field

doh

- make face caching mandatory, and pester users to enable it
- implement rate-limiting, for images only right now
- implement and document output-rate command to set rate limit.
- default 1mbit.

- MAJOR CHANGE
- you now need to use cfutil to install arches.
- former bigfaces are broken in the server
- bigfaces are no longer supported. at all.
- use face numbers instead of pointers
  * saves lotsa space
  * saves lotsa indirections
  * saves lots(?) cpu cycles
- completely rewrote face handling
- faces can now be added at runtime
- reload will add new faces
- this does not apply to animations
- use a hastable instead of binary search (faster) for faces
- face caching is broken
- facesets are gone
- server always reports MAX_FACES to any client who asks

- avoid negative event priorities like the plague. they are actually
  worse because they introduce random memory corruption and endless
  loops and worse, if worse exists.
- aggressively swap out maps when #actives exceeds threshold
- sweep and cede after server tick
- increase player command handling priorities, just in case.
- fix a bug in mortal checking, this was the reason for the
  enourmous memory leaks in map-world.ext
- mark c++-side watchers as non-reentrant

- move most last_* values into socket, where they belong
- this actually saved a lot of space in the text segment,
  which might mean less complicated pointer accesses, because
  the data is no where it belongs, mostly.

added some copyrights

- small, but subtle, rewrite of object management
- perl will now keep attachable objects alive
- objects are now refcounted
- refcouts need to be tested explicitly (refcnt_chk)
- explicit destroy is required current
- explicit destroy asks "nicely" for the object to self destruct, if possible
- refcounts will be used during mortal killing
- minor bugfixes, optimisations etc.
- some former hacks removed.

- add preliminary per-client coroutine support (I do not threaten, I act :)
- moved global events to cf::global

- made client a first-class crossfire-perl object
  (its attachable), but perl support is missing.
- added some client events
- fixed reply not working after logout

re-enable async command execution

overoptimise our sockets

- socket i/o is completely asynchronous now
- some command sare handled immediately
- others (most palying related commands) are queued
  for later (as of now synchronous) processing
- specifying a max queue length (in seconds) is possible, but disabled
- also add some syntax sugar for network code

- implement event watcher autoncancellation on reload
- used it everywhere
- removed lots of compatibility cruft
  - configure does no longer check for mandatory unix functionality/headers
  - confgiure now runs much faster

- implement c++ interface to Event->io watchers
- cut number of write()'s the server does in half

moar\! rewrite\!

(intermediate check-in for recoverability)

- medium decruftification
- medium cleanups
- make settings accessible to perl using cf::settings->mutator
  (completely untested)

added many accessors and mutators to struct player, including *title* and (hint, hint) *own_title*

indent

expand initial tabs to spaces

support health stats in an extensible way in map1

Made server compile with C++.
Removed cfanim plugin and crossedit.
C++ here we come.
