c89 compliant? ( #237 )
...
* Replace C++ comments into C comments
* Move INLINE out of Makefile.common, move to fceu-types.h
An INLINE define is still existing in Makefile.common for msvc (dont
have a way to to test that). Moved the rest into fceu-types.h using the
one already existing from emu2413.h.
* Increase maximum volume for apu channels
