Description: Export inline functions when building library
 This patch adds a preprocessor flag DSFMT_BUILDING_LIB that when
 specified causes the compiler to emit symbols for inline functions,
 which is achieved using C99 extern inline function declarations.
 This allows invoking these functions in programs that dynamically
 load the library for use with a foreign function interface (FFI).
