fix Bug #14103 IM tests fail on SCO

server-tools/instance-manager/listener.cc:
  every new connection should have sufficient thread stack to
  handle all IM commands
server-tools/instance-manager/manager.cc:
  change stack size of listener and guardian threads
server-tools/instance-manager/priv.cc:
  Add a new function, which is a wrapper around pthread_create to increase the stack size
server-tools/instance-manager/priv.h:
  declare new function
