The problem appeared because the same values produced different hash
during INSERT and SELECT for VARCHAR data type.
Fix:
VARCHAR required special treatment to avoid hashing of length bytes
(leftmost one or two bytes) as well as trailing bytes beyond real length,
which could contain garbage. Fix is done by introducing hash() - new method
in the Field class.

Review fixes

don't add CFLAGS/CXXFLAGS to ./configure command line in config.status
but _do_ add them before calling plugins' configure scripts
