percona-toolkit/t/lib/TableNibbler.t
svetasmirnova 59b80afe93 PT-2156 - Fix tests for lib 
- Impoved the fix for PT-2016, so it does not files with keys with USING keyword
- Added brackets to expression in lib/TableNibbler.pm, so it does not crap query wit many indexes with OR keyword
- Adjusted test t/lib/TableNibbler.t, so it reflects above chages
- Modified lib/Cxn.pm, so it has workaround for https://github.com/perl5-dbi/DBD-mysql/issues/306 , introduced in DBD::mysql 4.0.50
- Updated tests: added debugging code and cleanups
- Updated modules for tools
