made IM to work with --defaults-file smoothly

BitKeeper/deleted/.del-my.cnf~9322f78f12eb2f3c:
  Delete: support-files/my.cnf
include/my_sys.h:
  fixed prototype to reflect changes in default.c
mysys/default.c:
  use my_search_option_files instead of process_default_option_files. This is used from the IM.
server-tools/instance-manager/instance.cc:
  added parameter to complete_initialization(). this ine marks whether we are creating the only instance
  (for instance, when no config file given)
server-tools/instance-manager/instance.h:
  prototype changed
server-tools/instance-manager/instance_map.cc:
  Now call my_search_option_files to work smootly with --defaults-file
server-tools/instance-manager/instance_map.h:
  added first_option member. This is set of mysqlmanager was started with --defaults-file or with
  --extra-defaults-file to be passed to the my_search_option_files
server-tools/instance-manager/instance_options.cc:
  if we have only one instance, name the pidfile `hostname`.pid for compatibility reasons.
server-tools/instance-manager/instance_options.h:
  header fixed according to .cc
server-tools/instance-manager/manager.cc:
  prototype fixed
server-tools/instance-manager/options.cc:
  save --defaults-file of --defaults-extra-file to pass it to my_search_option_files
server-tools/instance-manager/options.h:
  added an optin to save --default-file options
support-files/Makefile.am:
  revert changes
