Bug#56657: Test still uses "--exec rm -f ..." which is non-portable
Bug#56601: Test uses Unix path for temporary file, fails, and writes misleading message

Several tests that was written in a non portable way (failed on windows)

Fixed by
1) backporting the fix for replace_result to also apply to list_files
(mysqltest from mysql-trunk)
2) replacing all #p#/#sp#/#tmp# to #P#/#SP#/#TMP#/
(innodb always converts filenames to lower case in windows).
3) replacing '--exec rm -f' with '--remove_files_wildcard'
4) replacing a perl snippet with '--write_file'
