respect iso c namespace in stdio.h and wchar.h regarding va_list
despite declaring functions that take arguments of type va_list, these headers are not permitted by the c standard to expose the definition of va_list, so an alias for the type must be used. the name __isoc_va_list was chosen to convey that the purpose of this alternate name is for iso c conformance, and to avoid the multitude of names which gcc mangles with its hideous "fixincludes" monstrosity, leading to serious header breakage if these "fixes" are run.
