14779f5cd4 wsd: return moved socket state to stop any IO processing 
Once a socket has changed ownership to a new
poll it will assert thread affinity with said
new poll. So we cannot do any IO on the old
poll's thread at that point and on.

9381d4134f Unify and simplify timeout and poll events setup. 
Both happen at the same time, and need support from the
SocketHandlerInterface.

Rename hasQueuedWrites to getPollEvents and merge updateTimeout.

a5a227e9a3 Re-work socket buffer options, sizing and setting. 
Only set nodelay and small socket buffers on WebSockets.
Avoid writing more data than can be absorbed by our socket buffer.
It is fine to set socket buffer sizes after bind/accept.

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.
