Jakub Jelen 4e56c5c956 poll: Avoid passing other events to callbacks when called recursively
Some architectures (s390x) provide different poll events such as POLLHUP in case
the remote end closed the connection (and they keep reporting this forever).

This is an issue when the user provided callback registering this event as an
error and tries to send some reply (for example EOF) using
`ssh_channel_send_eof()` which will lead to infinite recursion and sefgaults.

This was not solved by the 30b5a2e33b because the
POLLHUP event is not provided by the poll in events bitfield, but only reported
by the poll in revents bit field thus we need to filter these events later on
when the poll is recursively.

Fixes #202

 The SSH library

Why?

Why not ? :) I've began to work on my own implementation of the ssh protocol because i didn't like the currently public ones. Not any allowed you to import and use the functions as a powerful library, and so i worked on a library-based SSH implementation which was non-existing in the free and open source software world.

How/Who?

If you downloaded this file, you must know what it is : a library for accessing ssh client services through C libraries calls in a simple manner. Everybody can use this software under the terms of the LGPL - see the COPYING file

If you ask yourself how to compile libssh, please read INSTALL before anything.
