constant does not match type

const epics::pvData::int16 INVALID_DATA_TYPE = 0xFFFF;

0xFFFF does not fit in an int16. MSVC complains with the warning

src\pva\pv\pvaConstants.h(76): warning C4309: 'initializing': truncation of constant value

Consider either using the data type uint16 or the value -1 or remove the constant altogether as it seems not to be used anywhere.

A PR would be welcomed.

I wanted to give you the opportunity to choose one of the 3 solutions. Choosing option 3 now...

As I found another 0xFFFF -> int16 warning, I fixed both in one PR #215 replacing the value with -1.
The first PR #213 (removing the seemingly unused constant) might break external software depending on it.
