This fixes an inconsistency since
fed7e7a78b (ntdll: Simulate a syscall
return when starting a thread); in that commit, on i386 and
x86_64, the syscall_frame used for starting the thread was
zeroed with a memset, while it wasn't on arm and arm64.
This had a noticable effect on float maths, where the
uninitialized frame->restore_flags field could have the
CONTEXT_FLOATING_POINT bit set. (call_init_thunk only ORs in
CONTEXT_INTEGER into the restore_flags field, on all architectures).
If that bit was set, it would restore uninitialized data into the
fpscr register, possibly setting the FPU in a nondefault rounding
mode.

On non-AVX CPUs, CONTEXT_EX is not being initialized.
In WOW64 mode, this results in invalid exception records when
dispatch_wow_exception() uses RtlCopyContext().

The 'status' field of recv_socket_request is always either
STATUS_PENDING or STATUS_DEVICE_NOT_READY, and the 'total' field is
always zero.
Replace the 'status' field with 'force_async' boolean field, and get rid
of the 'total' field entirely.
Also, clean up the recv_socket handler code a bit.

Otherwise, try_recv() call from sock_recv() may race against try_recv()
call from async_recv_proc(), shuffling the packet order.

Make recv_socket alert the async immediately if poll() call detects that
there are incoming data in the socket, bypassing the wineserver's main
polling loop.

The IP_TOS control data is 1 byte on Unix, but 4 bytes on Windows.
Properly zero-extend the value instead of copying 3 bytes of garbage.
