[jdk9] (S) RFR: 8165463: Native implementation of sunmscapi should use operator new (nothrow) for allocations

[Ivan Gerasimov]

Hello!

In the native layer of sunmscapi provider, for memory allocations the 
::operator new() is used.
In (a very unlikely) case of failure, it will raise a C++ exception of 
type bad_alloc, which is bad, as we don't have handling code.

One simple way to improve the situation would be to use ::operator new 
(std::nothrow), which will just return zero to indicate a failure 
instead of throwing an exception.
Then we can (try to) throw a Java exception of type OutOfMemoryError.

Would you please help review the fix?
