Add __v*printf_internal with flags arguments
There are a lot more printf variants than there are scanf variants, and the code for setting up and tearing down their custom FILE variants around the call to __vf(w)printf is more complicated and variable. Therefore, I have added _internal versions of all the v*printf variants, rather than introducing helper routines so that they can all directly call __vf(w)printf_internal, as was done with scanf. As with the scanf changes, in this patch the _internal functions still look at the environmental mode bits and all callers pass 0 for the flags parameter. Several of the affected public functions had _IO_ name aliases that were not exported (but, in one case, appeared in libio.h anyway); I was originally planning to leave them as aliases to avoid having to touch internal callers, but it turns out ldbl_*_alias only work for exported symbols, so they've all been removed instead. It also turns out there were hardly any internal callers. _IO_vsprintf and _IO_vfprintf *are* exported, so those two stick around. Summary for the changes to each of the affected symbols: _IO_vfprintf, _IO_vsprintf: All internal calls removed, thus the internal declarations, as well as uses of libc_hidden_proto and libc_hidden_def, were also removed. The external symbol is now exposed via uses of ldbl_strong_alias to __vfprintf_internal and __vsprintf_internal, respectively. _IO_vasprintf, _IO_vdprintf, _IO_vsnprintf, _IO_vfwprintf, _IO_vswprintf, _IO_obstack_vprintf, _IO_obstack_printf: All internal calls removed, thus declaration in internal headers were also removed. They were never exported, so there are no aliases tying them to the internal functions. I.e.: entirely gone. __vsnprintf: Internal calls were always preceded by macros such as #define __vsnprintf _IO_vsnprintf, and #define __vsnprintf vsnprintf The macros were removed and their uses replaced with calls to the new internal function __vsnprintf_internal. Since there were no internal calls, the internal declaration was also removed. The external symbol is preserved with ldbl_weak_alias to ___vsnprintf. __vfwprintf: All internal calls converted into calls to __vfwprintf_internal, thus the internal declaration was removed. The function is now a wrapper that calls __vfwprintf_internal. The external symbol is preserved. __vswprintf: Similarly, but no external symbol. __vasprintf, __vdprintf, __vfprintf, __vsprintf: New internal wrappers. Not exported. vasprintf, vdprintf, vfprintf, vsprintf, vsnprintf, vfwprintf, vswprintf, obstack_vprintf, obstack_printf: These functions used to be aliases to the respective _IO_* function, they are now aliases to their respective __* functions. Tested for powerpc and powerpc64le.
