Matt Joyce f3b8138239 Add _REENT_ERRNO(ptr)
Add a _REENT_ERRNO() macro to encapsulate the access to the
_errno member of struct reent. This will help to replace the
structure member with a thread-local storage object in a follow
up patch.

Replace uses of __errno_r() with _REENT_ERRNO().  Keep __errno_r() macro for
potential users outside of Newlib.

Keith Packard 92068f4cc5 stdio: Parse 0x0p+00 correctly in scanf
The scanf code was skipping the '0' after the 'x' causing the
resulting buffer to contain an invalid number when passed to strtod.

Corinna Vinschen 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.

Corinna Vinschen 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.

Corinna Vinschen 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.

Corinna Vinschen 1bbdb3c953 newlib: [w]scanf: Fix behaviour on matching failure
The special handling of %\0 in [w]scanf is flawed.  It's just a
matching failure and should be handled as such.  scanf also
fakes an int input value on %X with X being an invalid conversion
char.  This is also just a matching failure and should be handled
the same way as %\0.

There's no indication of the reason for this "disgusting
backwards compatibility hacks" in the logs, given this
code made it into newlib before setting up the CVS repo.

Just handle these cases identically as matching failures.

Corinna Vinschen d16a56306d Consolidate wctomb/mbtowc calls for POSIX-1.2008
- Remove charset parameter from low level __foo_wctomb/__foo_mbtowc calls.
- Instead, create array of function for ISO and Windows codepages to point
  to function which does not require to evaluate the charset string on
  each call.  Create matching helper functions.  I.e., __iso_wctomb,
  __iso_mbtowc, __cp_wctomb and __cp_mbtowc are functions returning the
  right function pointer now.
- Create __WCTOMB/__MBTOWC macros utilizing per-reent locale and replace
  calls to __wctomb/__mbtowc with calls to __WCTOMB/__MBTOWC.
- Drop global __wctomb/__mbtowc vars.
- Utilize aforementioned changes in Cygwin to get rid of charset in other,
  calling functions and simplify the code.
- In Cygwin restrict global cygheap locale info to the job performed
  by internal_setlocale.  Use UTF-8 instead of ASCII on the fly in
  internal conversion functions.
- In Cygwin dll_entry, make sure to initialize a TLS area with a NULL
  _REENT->_locale pointer.  Add comment to explain why.
