Also internally used class Value is changed to use SQLString, instead of
(smart) pointer to it. Added missing SQLString object creation/destruction in
that class.
Checking in appveyor initial configuration.
Added windows test (try) to travis config.
It choked on const initialization with constexpr
Second possible issue was with
REASON_UNKNOWN in the ClientInfoStatus enum. It clashes with define in
one of Windows headers(Winreg.h). Added undersore prefix to the name.
Also fixed most often warning there.
Additionaly the commit contains some fixes in test faramework and in
tests.
Added missing headers to msi. Headers now installed into include/mariadb
ALl headers have been renamed from .h to .hpp
ConnCpp.hpp renamed to conncpp.hpp(all small letters)
All headers but conncpp.hpp, have been moved to conncpp subdirectory in
include, and in the msi
All exception classes have got explicit (exported from dll on Windows) copyconstructor
decluration, and definition of those constructors in the connector
library. And to stay on the safe side, all other constructors and
destructors definitions have been moved to library side.
Fixed the error, that few exception methods were declared as
dllimported, and defined in the header at the same time.
