BUG#9879 delimiter command discrepancy (4.1 vs. 5.0, mysql vs. mysqltest)

- Added testcases to test delimiters in 5.0
 - In 5.0 it's allowed to have a up to 16 byte string as delimiter, everything after the delimiter token will be treated as the delimiter. It's even allowed to set delimiter to 'delimiter', ':;' or'MySQL'
