a49209d2bc newlib: vf[w]scanf: Fix conversion multibyte <-> wchar_t 
* vfscanf: per POSIX, if the target type is wchar_t, the width is
  counted in (multibyte) characters, not in bytes.

* vfscanf: Handle UTF-8 multibyte sequences converted to surrogate
  pairs on UTF-16 systems.

* vfwscanf: Don't count high surrogates in input against field width
  counting.  Per POSIX, input is

9638c07527 newlib: vf[w]scanf: Drop width computation mixup 
The width value keeps the maximum field width.  This is the maximum
field width of the *input*.  It's *never* to be used in conjunction
with the number of bytes or characters written to the output argument.

However, especially in vfwscanf, the code is partially taken from
NetBSD which erroneously subtracts the number of multibyte chars
written to the argument from the width variable, thus potentially
subtracting up to MB_CUR_MAX from width for a single character in
the input stream.

To make matters worse, the previous patch adding %m added basically
the same mistake for 'c' type input.

Fix it.

d43863f569 newlib: vf[w]scanf: Implement POSIX %m modifier 
* The new code is guarded with _WANT_IO_POSIX_EXTENSIONS, but
  this is automatically enabled with _WANT_IO_C99_FORMATS for now.

* vfscanf neglects to implement %l[, so %ml[ is not implemented yet
  either.

* Sidenote: vfwscanf doesn't allow ranges in %[ yet.  Strictly this
  is allowed per POSIX, but it differes from vfscanf as well as from
  glibc.

0fd2c9bd12 newlib: vf[w]scanf: add validity checks 
POSIX requires that directive characters appear in a certain sequence:

1. '%' or '%<n>$'
2. optional '*'
3. optional field width digits
4. optional 'm' (not yet implemented)
5. optional length modifier ('l', 'L', 'll', 'h', 'hh', 'j', 't', 'z')
6. conversion specifier ('d', 's', etc)

Add a few basic validity checks to that effect, otherwise reject
directive as match failure.
