Disable warning 4710 for Windows builds (#186)

* Disable warning 4710 for Windows builds

* Suppress compiler warnings for inline and padding

Added pragma warning directives to suppress specific compiler warnings.

* Fix pragma warning directive in kdbsolace.cpp

* Suppress unused parameter warnings in callbacks

* Handle unused parameters in K functions

Added unused parameter handling in destroy_solace and version_solace functions.

* Fix pragma warning disable syntax in kdbsolace.cpp
