Fixed Bug#19479:mysqldump creates invalid dump.

Only check for FN_DEVCHAR in filenames if FN_DEVCHAR is defined.
This allows to use table names with ":" on non windows platforms.
On Windows platform get an error if you use table name that contains FN_DEVCHAR


include/config-win.h:
  Moved FN_DEVCHAR to config-win.h
include/my_global.h:
  Moved FN_DEVCHAR to config-win.h
mysql-test/r/create.result:
  Added testcase for Bug#19479:mysqldump creates invalid dump
BitKeeper/etc/ignore:
  Added sql/share/iso639-2.txt sql/share/fixerrmsg.pl to the ignore list
mysql-test/t/create.test:
  Added testcase for Bug#19479:mysqldump creates invalid dump
mysys/mf_fn_ext.c:
  Added checking of BASKSLASH_MBTAIL as dirname_part depends on it.
  Fixed cast and indentation.
sql/table.cc:
  Only check for FN_DEVCHAR in filenames if FN_DEVCHAR is defined.
