Add locking to the random(3) family of functions to gain
thread-safety per POSIX. Use NetBSD version of the file as
role-model.

GCC 7 is able to see straight through this trick, so use a more formal
method to avoid the warning.

Commit 6f3943b erroneously removed the `#ifdef _COMPILING_NEWLIB'
guarding the __getreent inline function. This patch ignored the
fact that config.h is included when building applications, and the
code in question requires internal, auto-generated headers to be
available which are not exposed to user-space.
Reinstantiate defined(_COMPILING_NEWLIB) test and alternatively
check for defined (__INSIDE_CYGWIN__), otherwise we'd have to
reinstantiate the __getreent macro in cygtls.h which is really
confusing.
While testing it turned out that a low number of source codes inside
Cygwin won't see the inline __getreent due to a missing __INSIDE_CYGWIN__
definition. For malloc.cc this was actually deliberate to get different
definitions from including cygmalloc.h. Change this by defining
__INSIDE_CYGWIN__ in malloc.cc but changing the test in cygmalloc.h
to test for defined(DLMALLOC_VERSION). This might need a change if we
ever get around to replace dlmalloc with a newer, more threading-aware
malloc implementation.

setstate is supposed to take a char *, not a const char *.

/dev/random calls getentropy. So there's no good reason to go out of
our way to open /dev/random just to call getentropy anyway.
* random.cc (srandomdev): Drop opening /dev/random in favor of
calling getentropy.
