Peter Foley fa6a5a3a74 Use DnsFree instead of deprecated DnsRecordListFree
The latest version of the mingw headers have been updated to make
DnsRecordListFree an alias of DnsFree when targeting Windows XP or later.
Use DnsFree directly, avoiding the wrapper function.

/home/peter/cross/src/cygwin/winsup/cygwin/libc/minires-os-if.c:289:
undefined reference to `DnsFree'

winsup/cygwin/ChangeLog
autoload.cc: Load DnsFree rather then DnsRecordListFree
libc/minires-os-if.cc (cygwin_query): Use DnsFree rather then DnsRecordListFree

When running RTEMS paravirtualized in user space, the cli/sti instructions
can't be used. But I can't see why they are needed in either user or
supervisor state. Turning the use of them off for RTEMS.

This code is unmodified since the beginning of the repository, so I have
no insight into why it was done. I may even have been the one to add them.
Absolutely no idea except they aren't necessary.

Corinna Vinschen e42f66d00f Remove ill-advised cygwin_props
Cygwin_props have been invented to allow switching off the unique
installation keys in the first place, supposedly for debugging.
This never really was a good idea, after all we *want* the installations
to be independent and there's no good reason to break that, not even
for debugging purposes.

Other than that, cygwin_props were meant to be used for some other global
settings which never took place.  There's just no good reason to tweak
the DLL binary invisibly where a setting could be done in a file or the
environment.

This patch removes the cygwin_props entirely, including the related
settings in cygcheck.

cygwin:
	* cygprops.h: Remove file.
	* globals.cc (cygwin_props): Remove.
	* cygheap.cc (init_cygheap::init_installation_root): Drop removing

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:
