sys/types.h: Don't include sys/_stdint.h

By including sys/_stdint.h, all types from stdint.h are
exposed even if stdint.h isn't pulled in explicitely. Include
<machine/_default_types.h instead. Fix up newlib and Cygwin
files which rely on stdint.h types, too.

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:

http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/lib/libcrypto/crypto/getentropy_win.c?rev=1.4&content-type=text/x-cvsweb-markup

	* libc/include/stdlib.h (arc4random): Declare if __BSD_VISIBLE.
	(arc4random_buf): Likewise.
	(arc4random_uniform): Likewise.
	* libc/include/sys/unistd.h (getentropy): Likewise.
	* libc/include/machine/_arc4random.h: New file.
	* libc/stdlib/arc4random.c: Likewise.
	* libc/stdlib/arc4random.h: Likewise.
	* libc/stdlib/arc4random_uniform.c: Likewise.
	* libc/stdlib/chacha_private.h: Likewise.
	* libc/sys/rtems/include/machine/_arc4random.h: Likewise.
	* libc/stdlib/Makefile.am (EXTENDED_SOURCES): Add arc4random.c
	and arc4random_uniform.c.
	* libc/stdlib/Makefile.in: Regenerate.
