Bug#35335 funcs_1: Some tests fail within load_file during
                      pushbuild runs
   Solution: 1. Move files with input data used in load_file, 
                load data etc. 
                from suite/funcs_1/<whatever>
                to std_data
             2. Use for testsuite funcs_1 the server option
                --secure-file-priv=<MYSQLTEST_VARDIR>
             3. Outfiles have to be stored under MYSQLTEST_VARDIR 
+ changes according to WL#4304 Cleanup in funcs_1 tests
  - backport of fixes/improvements made in 5.1 to 5.0
    The differences between scripts in 5.0 and 5.1 cause
    much additional and annoying work during any upmerge.
  - replace error numbers with names
  - improved comments
  - improved formatting
  - Unify storage engine names so that result files for
    storage engine variants do not differ (some tests)
  - remove a script no more used (tests are done in other scripts)
