Fix exploit where books inscribed or marking runes created by players could
contain special text such as "@match" or "@eval" which would allow them to
execute arbitrary code.

refactoring of shstr classe,s new shstr_tmp, lots of minor rewriting

smell, remove gcfclient support, material fixes, cfpod parse fixes, refactoring

lotsa

better logging, remove cruft

add some primitive memory debugging

add slice and shstr statistics

first, untested, try at spicing up the message system

rather uncertain optimisation.. trying to take advantage of cmov instructions
if refptr.

note no jumps but larger codeside (1.7kb net increase).

- improve dynbuf implementation further
- save now saves shstrs longer than HUGE_BUF, lets fix any brokenness remaining
  in the server...
- converted most describe_*-functions to dynbuf_text, making them likely
  faster (or maybe slower), while removing any hardcoded length limit.
- memory allocated for static dynbuf's is not being returned ever (at least
  not the initial chunk, maybe fix this?)
- implement framework for predeclared const shstrs for comparison purposes
  (shstrinc.h).
- enabled and enforced new material code.
- implement hack to clean up book titles.
- increases HUGE_BUF to 10240, to be similar to mac network packet size.

- new map header boolean "no_reset 1" to deny reset.
- allow reset of per-player maps, effectviely implementing
  player-private dungeons.
- re-enabled reset-on-load feature again.
- remove fail-safe mechanism that prevented per-player maps from
  being reset. keep your fingers crossed.
- fixed two bugs in archetype finding (archname vs. object name).
- singularities no longer crash the server but will log a backtrace
  now as they are really are fatal.

update copyrights in common/*.C and util/*.C

cleanup

instrument random_roll with new logBacktrace and pray that it works

- add format utility function.
- split dynbuf into dynbuf and dynbuf_text.
- use dynbuf_text for examine strings instead of
  outputting each line seperately. tried to use stringstreams
  but they add insane overheads (as does std::string, but less so).

- fix tausworthe generator initialisation (no big deal)
- use numerically more correct multiplication instead
  of remainder. this has surprisingly good consequences
  (which I originally didn't expect):
  - the generated code is smaller and faster
  - gcc optimises the 64 bit arithmetic extremely well on 32 bit archs.
  - behaviour for negative and zero arguments (both illegal) is
    pretty well-behaved.

rework material code in preparation for nuking object->materials, also add some useful object methods in preparation of the mapspace limiting

- experimentall.y determine minimum random map size (12)
- harden random map generator by stresstesting
- reduced codesize while increasing readability (RANDOM => rndm)
- fixed a likely unimportant bug in random_roll64
- possibly broke lots of code

fix random number generator seeding

RANDOM was broken due to signedness issues, also rewrote random_roll, no longer uses luck, but should

comments

- fix crash bug
- better fork & abort (untested)

this is close to working

- style maps need very special treatment
- cf has a nonzero chance of crashing in a random map

the big rename

- 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.

- minor cleanups
- minor optimisations (in_player vs. is_player_inv)
- added P_PLAYER map flag
- some (dead) concept code

another bug, do some adjustments to coredumping 'algorithm'

- 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

replace some function- by method-calls

lld -> I64_PFd

* remove arch.h
* use refcounting for archetypes
* cleanup
* strat of generic garbage collector

indent

tuning

- improve assign to prepend "..."
- make more use of assign
- implement op->debug_desc() and make some more use of it

indent

genaccess, take three

Cleaned up code a little.

THIS CODE WILL NOT COMPILE
use the STABLE tag instead.

- major changes in object lifetime and memory management
- replaced manual refcounting by shstr class
- removed quest system
- many optimisations
- major changes

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