97e9463f17 Revert "wsd: TerminatingPoll always starts its own thread" 
This reverts commit 388d7b1dbf.

It is vital to have clean control of thread start. By starting
a thread during init. of a member (or base-clase) we loose lots of
control, some examples:

	Any members initialized after a member that auto-starts a
	thread, is effectively un-defined, and cannot be accessed
	reliably.

	This is particularly problematic for sub-classes.

	I've seen threads started before the base-class has
	finished constructing in the original creating thread -
	such that the vtable was not yet updated to the sub-class
	causing the transient parent vtable used during construction
	to be used in-error.

a9d5801c37 Unwind releaseSocket complexity. 
We only move sockets in response to input on the socket, which
must happen in the thread that we're processing that input on.

b8af470918 nb: serve files synchronously 
As there isn't support (yet) to send files
asynchronously, when the socket native buffer
is small, asynchronous writes naturally return
EWOULDBLOCK. As a temp solution, we send files
synchronously, so there is no need to poll.

This should be replaced witha file-server
polling/serving thread that is dedicated to
sending files only (which closes the connection
when done).

e184a371a0 nb: write socket buffer to socket safely 
Since a socket client can push data into
the socket in a different thread than the one
polling (indeed that's the only possible scenario),
the write buffer must be protected by a lock.

On the other hand, the read buffer is always
invoked from a single thread, the polling. So
it is perfectly safe without locks.

31dd434136 nb: drain the read buffer before dispatching 
Draining the buffer is the correct appraoch
to avoid accumulating data in the kernel
unnecessarily. But it also reduces the overhead
of reparsing the incoming data for message
boundaries.

The client that is to parse the data should
parse as many messages as possible and remove
them from the socket buffer.

Finally, we probably need to cap the maximum
buffer size to avoid bloating. However this
heavily depends on the application's max
message size, assuming there is no separate
buffer beyond that of the socket to accumulate
the messages in.

f086079d25 nb: SocketPoll class to poll events on N-Sockets 
Internally SocketPoll manages the sockets
and handles the polling and firing of callback.

It's thread-safe and handles asynchronous calls
to remove sockets correctly while potentially
being in poll(2).

The choice for using poll(2) compared to epoll
or select are the following:

1. For our use-case, poll(2) works great up to
   a few hundred sockets, which we don't expect
   to have on a single document normally.

2. select(2) has an awkward API (modifies input,
   f.e) and has limit on max fds that we need to
   be mindful of (even if we'll not hit it in
   practice). poll(2) preserves the input and has
   a no-nonsense API that's simple and readable.

3. While select(2) is the most portable, poll(2)
   isn't far behind. Yet in practice we'll probably
   not support other systems than Linux.

4. epoll(2) starts to scale with hundreds or
   thousands of sockets. Meanwhile, it has high
   overhead to adding/removing sockets (context
   switch to kernel and back). Our typical case
   will have a handful to a dozen sockets.
   Hardly a justification for epoll's heavy guns.

1e2f7a9f65 nb: bind reuses address automatically 
This is virtually always desirable, since
without it we may fail to bind after recycling
if the previous socket is TIME_WAIT.

However, if a socket is bound to same address
this will not prevent the failure to bind,
and we'll detect that the address/port is busy.

So the advantage is in minimizing recycling time.
