Exported header files should not include internal headers. Fix that. Exported header files should not use the bool type. So far we opted to stick to C89 for exported headers, and hence use "int" for bools in them. Continue to do so. Exported header files should have #include lines for everything they use including inttypes.h and sys/types.h, so that they may be included in any order. Exported header files should have C++ guards, hence add them. Exported header files should not use gcc extensions like #pragma once, get rid of it.
