Serguey Zefirov 0bc384d5f0 fix(ubsan): MCOL-5844 - iron out UBSAN reports
The most important fix here is the fix of possible buffer overrun in
DATEFORMAT() function. A "%W" format, repeated enough times, would
overflow the 256-bytes buffer for result. Now we use ostringstream to
construct result and we are safe.

Changes in date/time projection functions made me fix difference between
us and server behavior. The new, better behavior is reflected in changes
in tests' results.

Also, there was incorrect logic in TRUNCATE() and ROUND() functions in
computing the decimal "shift."
