Max open files handling moved to my_set_max_open_files()

This ensures that my_file_info takes this the max number of files into account and one can now use --open-files-limit on windows to increase number of used files up to 2048


client/client_priv.h:
  Added --open-files-limit to mysqlbinlog
client/mysqlbinlog.cc:
  Added --open-files-limit to mysqlbinlog
include/config-win.h:
  Define that you can have up to 2048 files open on windows
include/my_global.h:
  Allow override of OS_FILE_LIMIT
include/my_sys.h:
  Cleanup
  Added prototypes for my_set_max_open_files() and my_free_open_files()
libmysql/Makefile.shared:
  Added my_file.c
myisam/myisamlog.c:
  Use my_set_max_open_files()
mysys/Makefile.am:
  Use my_file.c (for mysqlbinlog)
mysys/my_alloc.c:
  Remove compiler warning
mysys/my_div.c:
  MY_NFILE -> my_file_limit
mysys/my_dup.c:
  MY_NFILE -> my_file_limit
mysys/my_fopen.c:
  MY_NFILE -> my_file_limit
mysys/my_open.c:
  MY_NFILE -> my_file_limit
mysys/my_static.c:
  Allow changing of open files limit
mysys/my_static.h:
  Allow changing of open files limit
sql/mysqld.cc:
  Max open files handling moved to my_set_max_open_files()
