This patch moves  _itoa.h to sysdeps/generic. I left _itowa.h in stdio-common
since it is only used in stdio-common.  I added

#ifndef _ITOA_NEEDED
# define _ITOA_NEEDED		(LONG_MAX != LLONG_MAX)
#endif
#ifndef _ITOA_WORD_TYPE
# define _ITOA_WORD_TYPE	unsigned long int
#endif

to  _itoa.h and

#ifndef _ITOWA_NEEDED
# define _ITOWA_NEEDED		(LONG_MAX != LLONG_MAX)
#endif
#ifndef _ITOWA_WORD_TYPE
# define _ITOWA_WORD_TYPE	unsigned long int
#endif

to itowa.h.  I added _itowa macro if _ITOWA_NEEDED false since it
is used in vfprintf.c to output long long.  Tested on Linux/ia32, Linux/x86-64
and Linux/x32.  OK to install?

Thanks.
