[Socket] shutdown on end

Calling stream_socket_shutdown when closing a client

the connection is closed.
stream_socket_shutdown will immediately drop the TCP peer

  [Socket] shutdown on end
[Socket] on end shutdown read+write
[EventLoop] Stop loop before throwing exception (removing stream is not enough)
[Socket] Buffering large messages

Added a chunkSize parameter to set the number of bytes the buffer will write at one time
The write listener will only be removed when the buffer has been emptied
Removed exception error handler:
fwrite can send data AND trigger an error, the exception destroyed the $sent variable
