calls with stack_size > 16 pop argument values into x3, overwriting
the number of 16-byte stack octwords. This breaks the checks for popping
x4..x7 and potentially unbalances sp (based on the vaue of args[16..23]).
Use a scratch register (x9) for this count so its lifetime does not
conflict with preparing the parameter/result registers.

This is required to correctly support out reference parameters,
otherwise server method receives not initialized pointers during
the CALLSERVER phase and crashes.

Based on NdrStubCall2 and NdrAsyncClientCall implementations.
In order to test asynchronous RPC I used dlls/rpcrt4/tests/server.c as a base,
converted int_return() and sum() to use asynchronous RPC on both client and
server sides (server.idl doesn't need any changes), and added server.acf:
interface IServer
{
[async] int_return();
[async] sum();
}
With this implementation these tests pass under Wine. Since widl doesn't
support asynchronous RPC it's impossible to add appropriate Wine tests.

Otherwise the caller may decide to wait for the call termination which
will never happen.

NdrClientCall already uses TRY/EXCEPT block if the procedure has
Oi_HAS_COMM_OR_FAULT in its Oi_flags, I've added similar block
to NdrAsyncClientCall but without mapping the fault code using
CommFaultOffsets because NdrAsyncClientCall doesn't have this
implemented.
An installer that I have here calls NdrAsyncClientCall in order
to query status of a not yet installed service, and that leads
to a crash due to RaiseException from inside of NdrAsyncClientCall.
With this patch it no longer crashes on an unhandled exception,
and then installs the service.

Most notably in NdrProxyInitialize().
This patch and the next bring the scope of exception handling roughly in line
with -Os stubs.

Avoids an unhandled exception. Passing NULL as a ref pointer (which a
top-level [out] parameter necessarily is) is illegal, but this will be caught
in the CALCSIZE pass. This matches midl/widl behaviour in the -Os case.

In the simple reference case the freer will not see the top-level
pointer, so we need to free that here.
This fixes a double-free caused by commit 614afcefa3.
