network: Add pending close on disconnect for non-empty write buffer

Similarly to 1b19f660 (which added socket flushing before close), the
socket should have a chance to disconnect if the write buffer is not
empty. Instead of flushing, the pendingClose is added so that the
backend may disconnect the socket once these bytes have been written.

winrt: Fix socket descriptor storage in native socket engine

This stores the socket pointer in the descriptor, rather than an
abitrary handle, so that it is easier to access from e.g. SSL socket.

To further support SSL sockets, a special case for SSL sockets is
made so that the the socket reader installation can be delayed until
after the socket is encrypted (as this is the only supported mode of
operation with StreamSocket).

QVector: check d for equality before d->size for inequality

Assuming the CPU has already loaded 'this', the value of 'd' is just
an indirect load away. The value of d->size, however, is two indirect
loads away, one of which is the load of 'd'.

So it makes more sense to check for d-pointer equality first, as that
can proceed in parallel with the fetch for d->size, which the CPU
may speculatively trigger.

In addition, at least GCC in release mode after this change doesn't
set up the stack frame if the d-pointer check succeeds.

Micro-optimize QVector::count()

...by instantiating std::count() not with QVector::const_iterator, which is a

can be shared with other instantiations in the executable. It might also enable

builtin types.
