Support pragma once in all header files and cleanup some warnings (#4339)

Browse Source 
Summary:
As you know, almost all compilers support "pragma once" keyword instead of using include guards. To be keep consistency between header files, all header files are edited.

Besides this, try to fix some warnings about loss of data.
