* Simplify H5api_adpt.h
This change also uses the shared markup (e.g., __declspec) in both
static and shared libraries as the shared markup is ignored when
building static libs.
* Renamed some API decorations
Some API decorations (used to hide __declspec on Windows, among other
things) have been renamed:
H5_DLLCPP(VAR) --> H5CPP_DLL(VAR)
H5_HLDLL(VAR) --> H5HL_DLL(VAR)
H5_HLCPPDLL(VAR) --> H5CPP_HL_DLL(VAR)
H5_FCDLL(VAR) --> H5FC_DLL(VAR)
H5_FCTESTDLL(VAR) --> H5FC_TEST_DLL(VAR)
HDF5_HL_F90CSTUBDLL(VAR) --> H5FC_HL_DLL(VAR)
The shared library decorations are also now used when building static
libraries (where they are meaningless and ignored).
