+ return module base == NULL instead of handle if not known

+ rewritten dynlink.c, moved to libio

- reported by Jon, resolver was not checking for NXDOMAIN as well as SERVFAIL
  this caused odd DNS reports and took longer to connect.

  Tested by Jon (ThaPrince).

+ fixed unaligned memory reference in resolver

- optimized ircncmp()

- Entirely changed the way of ban match processing to be more cleaner.
  It also should nicely speed up matching of pure ip (may include cidr mask)
  bans.
- Removed match_cidr() which is now not longed needed
- Add back some prototypes to res.h to fix compile errors

 - Fixed some compile errors and some shadowed declarations.

- Moved has_wildcards() from m_list.c to match.c and re-use it
  in some other places.

+ ported rate limiting fixes from 7.2

+ moved max_watch to the beginning of 'registered users' subsection

* make win32 port work with libio.dll

- Fixed typo ...

- Removed two extra memsets in make_request()

- compile libio as a dll on win32
- next step is compiling the whole ircd as a dll to export its symbols
- after that, we'll be able to support loadable *.dll modules.

NOTE: m_operspy.c doesn't compile now (error at localClient->iline)

- fixed header name collision on linux *yawn*

- added dynamically extensible conf parser (compiles ok); enough to start
  modularising general{} -> general.c, auth{} -> auth.c and so on.

* attached misc/tools.c to misc/list.c,
  this should really have been done earlier.

* moved mem_frob() to memory.c

* single libio_init() instead of all startup functions;
  btw, I don't know if ircd's still able to boot ..

- further win32 fixes, use ircd_signal.c interface (signals are wrapped
  around WM_USER's wParam)
- note that the callback for WM_SIGNAL (ie WM_USER) defined in libio is
  independent from the ircd, ie variable dispatch_wm_signal is set in
  ircd_signal.c.
- now it compiles, to do: turn libio into a DLL to allow symbol references
  in m_*.dll protocol modules.

- stale .depend

- svn:keywords *smacks adx*

- splitted ircd/libio, all headers connected with libio sources have been
  moved for internal use only. To use libio interface, include "libio.h"
  (which is already done in "stdinc.h")

- removed external references from libio/net, still to do: comm

- removed external references from string/
- still to do : misc net comm

- split libio Makefiles for easier maintenance
- moved pcre.h to main include/ as it is currently a part
  of libio interface (in the future all such headers should
  be moved to libio/ and integrated...)

Now, libio components like comm, misc etc. should be as independent
as possible (from the rest of ircd and from each other), to allow
easy reuse in other software and to keep the interface clean.

- move non-irc related sources to /libio
- todo: make it independent of the rest of code
