Also it getBoolead was subotimal and significantly slowed down the
testsuite running.
Removed 5.5 server from travis config
Fixed database metadata test to skip one check with 10.1 server, as it
returns wrong data in many cases.
Moved common files to the separate OBJECT lib, as it looked like it is
quite difficult for the gcc to chew it.
Skipped tiem-outing test for now. Needs to be fixed.
The commit contains too many fixes to remember all of them, really. May
resultset navigation fixes. Crashes, caused by not initializing of some
properties in some classes, etc.
