dict0dict.c, dict0dict.h, fil0fil.c:

  Fix a problem in crash recovery of .ibd files on Windows if the user used lower_case_table_names=0 or 2; the directory scan in crash recovery forgot to put all paths to lower case, so that the tablespace name would be consistent with the internal data dictionary of InnoDB; remember that InnoDB puts internally all database names and table names to lower case on Windows, regardless of the value of lower_case_table_names
