create stdio.h and stdarg.h for {,v}snprintf Sometimes coreboot needs to compile external code (e.g. vboot_reference) using its own set of system header files. When these headers don't line up with C Standard Library, it causes problems. Create stdio.h and stdarg.h header files. Relocate snprintf into stdio.h and vsnprintf into stdarg.h from string.h. Chain include these header files from string.h, since coreboot doesn't care so much about the legacy POSIX location of these functions. Also move va_* definitions from vtxprintf.h into stdarg.h where they belong (in POSIX). Just use our own definitions regardless of GCC or LLVM. Add string.h header to a few C files which should have had it in the first place.
