Yaakov Selkowitz 97d1536d17 sparc64: move struct timeval to <sys/_timeval.h>
commit bb01594897 moved the struct timeval
declaration from <sys/time.h> to <sys/_timeval.h>, and commit
01885f533d changed <sys/select.h> to include
<sys/_timeval.h>.  Therefore, sparc64's own struct timeval needs to be
moved accordingly in order to avoid a conflict from the generic type.

Yaakov Selkowitz f049607eb0 Feature test macros overhaul: sparc64
sparc64 has a number of its own headers which override the generic ones.
These too need to use feature test macros properly.

These changes correspond to the generic fcntl.h and sys/stat.h changes
in commit d2df6d381b and
commit 069e400c91.

Sebastian Huber f74cf1350e Add arc4random() etc. from OpenBSD 5.8
According to the OpenBSD man page, "A Replacement Call for Random".  It
offers high quality random numbers derived from input data obtained by
the OpenBSD specific getentropy() system call which is declared in
<unistd.h> and must be implemented for each Newlib port externally.  The
arc4random() functions are used for example in LibreSSL and OpenSSH.

Cygwin provides currently its own implementation of the arc4random
family.  Maybe it makes sense to use this getentropy() implementation:

Yaakov Selkowitz 6ba26630e0 Feature test macros overhaul: sys/features.h
This is the complete rework of the feature tests macros for better
compatibility with GNU libc, primarily based on the Linux man pages
documentation:

http://man7.org/linux/man-pages/man7/feature_test_macros.7.html

The previous implementation was flawed in its approach that macros were
often used to hide symbols if defined (e.g. !defined __STRICT_ANSI__ or
!defined _POSIX_SOURCE), whereas the approach of glibc is that these macros
make symbols available when defined (e.g. defined _BSD_SOURCE, or as used
internally, #if __BSD_VISIBLE).  As much open-source software is written
with glibc in mind, this necessitated patching numerous packages just to
compile.

In particular, __STRICT_ANSI__ (which is defined by gcc -ansi or -std=c*)
was given too much importance.  This implementation limits the influence
of __STRICT_ANSI__ to controlling the default when no other feature test
macros are defined, and to the inclusion of <alloca.h> in <stdlib.h> as
documented.  These are the only places where __STRICT_ANSI__ should be
tested.

The following macros are now accepted: _ATFILE_SOURCE, _BSD_SOURCE,
_DEFAULT_SOURCE, _ISOC99_SOURCE, _ISOC11_SOURCE, _LARGEFILE_SOURCE,
_SVID_SOURCE, _XOPEN_SOURCE_EXTENDED.

The existing __*_VISIBLE internal macros have been kept mostly
compatible with the original BSD implementation, with some changes to
the criteria which controls them.  Several more macros in this style
have been added where needed for concision or accuracy.

Enabling C++11 or newer in the compiler also enables C99 and C11
functions.  Doing so should help move away from the need to define
_GNU_SOURCE in g++ for _GLIBCXX_USE_C99 support as on Linux:

Corinna Vinschen 1eb6db6efb Update setvbuf to latest OpenBSD implementation
Newlib's setvbuf function is very old and has two bugs:
- It sets the SRD/SWR flags incorrectly in case of files opened for
  reading and writing.
  See https://cygwin.com/ml/cygwin/2016-03/msg00180.html
  for a desription of the effect.
- It always sets the buffer size to BUFSIZ if it's not provided by
  the application, independent of the optimal blocksize for the
  underlying IO device.
