Corinna Vinschen 10b57ba8d0 cygwin: Document latest changes, bump API minor

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.

  to correct return value beforehand.  This is possible because _memcpy

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.

for readlink.  glibc also wraps the following functions:
confstr, getdomainname, getgroups, gethostname, getlogin_r, getwd, pread,
readlinkat, ttyname_r.

for parity with glibc.  The following functions are also guarded in glibc:
asprintf, dprintf, fprintf, printf, vasprintf, vdprintf, vfprintf, vprintf.

Yaakov Selkowitz 3e8fc7d9f2 ssp: add Object Size Checking common code 
The Object Size Checking (-D_FORTIFY_SOURCE=*) functionality provides
wrappers around functions suspectible to buffer overflows.  While
independent from Stack Smashing Protection (-fstack-protector*), they
are often used and implemented together.

While GCC also provides an implementation in libssp, it is completely
broken (CVE-2016-4973, RHBZ#1324759) and seemingly unfixable, as there
is no reliable way for a preprocessor macro to trigger a link flag.
Therefore, adding this here is necessary to make it work.

Note that this does require building gcc with --disable-libssp and
gcc_cv_libc_provides_ssp=yes.

Yaakov Selkowitz 0a5dfdbd1b ssp: add APIs for Stack Smashing Protection 
Compiling with any of the -fstack-protector* flags requires the
__stack_chk_guard data import (which needs to be initialized) and the
__stack_chk_fail{,_local} functions.  While GCC's own libssp can provide
these, it is better that we provide these ourselves.  The implementation
is custom due to being OS-specific.
