rawNdbDefaultvalue does not require a full-fledged Node Buffer
Implement bufferForText and textFromBuffer in C++.
Fix composition value checking
merge
less debugging output at end of test run
More TEXT tests for NDB
work on support for NdbRecord-backed ValueObjects which contain
TEXT or BLOB columns.
Fix bug of using Persistent<T>(x) rather than Persistent<T>::New(x)
All NDB read results (including those containing BLOB and TEXT columns)
are now ValueObjects.
