initial import of Windows port of IM.

server-tools/instance-manager/commands.cc:
  type cleanups for compiling on Windows
  now using Options::config_file for the location of the single 
  my.cnf file we are using
server-tools/instance-manager/guardian.cc:
  pthread_mutex_lock and unlock do not return a value on Windows
  so we return 0 in all cases
server-tools/instance-manager/instance.cc:
  big changes here.
  Had to implement Windows versions of launch_and_wait and kill()
server-tools/instance-manager/instance.h:
  added some function defs
server-tools/instance-manager/instance_map.cc:
  pthread_mutex_lock and unlock do not return a value on Windows
  Also, now using only the file named as Options::config_file
server-tools/instance-manager/instance_options.h:
  added reference to port.h
server-tools/instance-manager/listener.cc:
  reworked and simplified the socket handling code.
  Added windows versions of the code that sets the sockets to be
  non-blocking and non-inheritable
server-tools/instance-manager/listener.h:
  change Options to always be a struct.  Really surprised GCC was 
  letting this go.  Options was declared to be struct in some places
  and class in other places.
server-tools/instance-manager/log.cc:
  added reference to port.h
server-tools/instance-manager/manager.cc:
  moved all the signal code inside some #ifndef __WIN__ blocks
server-tools/instance-manager/manager.h:
  change Options to always be a struct.  Really surprised GCC was 
  letting this go.  Options was declared to be struct in some places
  and class in other places.
server-tools/instance-manager/mysqlmanager.cc:
  added in the Windows service code.
server-tools/instance-manager/options.cc:
  Added in the windows options for running as a service and the code
  for loading settings only from a single file
server-tools/instance-manager/options.h:
  added definitions for the new Windows service vars and routines
server-tools/instance-manager/parse_output.cc:
  added reference to port.h
server-tools/instance-manager/priv.cc:
  added reference to port.h
server-tools/instance-manager/priv.h:
  linuxthreads should not be visible on Windows
server-tools/instance-manager/thread_registry.cc:
  more __WIN__ blocking
server-tools/instance-manager/user_map.cc:
  fixed passwd file code to handle files with \r\n line endings
server-tools/instance-manager/IMService.cpp:
  New BitKeeper file ``server-tools/instance-manager/IMService.cpp''
server-tools/instance-manager/IMService.h:
  New BitKeeper file ``server-tools/instance-manager/IMService.h''
server-tools/instance-manager/WindowsService.cpp:
  New BitKeeper file ``server-tools/instance-manager/WindowsService.cpp''
server-tools/instance-manager/WindowsService.h:
  New BitKeeper file ``server-tools/instance-manager/WindowsService.h''
server-tools/instance-manager/mysqlmanager.vcproj:
