Splitted callMethods + ClassLoader fix + doxification.

	* kaffe/kaffevm/Makefile.am
	(libkaffevm_la_SOURCES): Added javacall.c

	* kaffe/kaffevm/Makefile.in: Regenerated.

	* kaffe/kaffevm/classMethod.c,
	kaffe/kaffevm/classMethod.h
	(initCollector): Moved to gc.h
	(parsed_signature): Added real_nargs.
	(PSIG_RNARGS): New macro.
	(KaffeVM_countRealNumberOfArgs): New function to retrieve the real
	number of argument slot used.

	Doxified a bit.

	* kaffe/kaffevm/gc.h
	(initCollector): Moved from classMethod.h

	* kaffe/kaffevm/javacall.c
	(KaffeVM_callMethodA, KaffeVM_callMethodV): Moved from support.c
	along with their macros.
	(KaffeVM_countRealNumberOfArgs): New function.

	kaffe/kaffevm/support.c:
	(KaffeVM_callMethodA, KaffeVM_callMethodV): Moved out.

	* libraries/clib/native/ClassLoader.c
	(loadClass): Check whether the class name is well constructed.
