* autoload.cc (CryptAcquireContextW): Remove.

	(CryptGenRandom): Remove.
	(CryptReleaseContext): Remove.
	(SystemFunction036): Define.  Add comment to explain that this is
	actually the RtlGenRandom function.
	* fhandler.h (class fhandler_dev_random): Drop crypt_prov member.
	(fhandler_dev_random::fhandler_dev_random): Define inline.
	(fhandler_dev_random::dup): Drop declaration.
	* fhandler_random.cc (fhandler_dev_random::fhandler_dev_random): Remove
	here.
	(fhandler_dev_random::crypt_gen_random): Use RtlGenRandom to drop
	dependency to old Crypto API.
	(fhandler_dev_random::read): Implement an enhanced version of reading
	random bytes from RtlGenRandom for the sake of a better /dev/random
	emulation.
	(fhandler_dev_random::close): Just return 0 since crypt_prov doesn't
	exisyt anymore.
	(fhandler_dev_random::dup): Drop entirely for the same reason.
