Summary: libssh2_poll handles -1 timeout incorrectly

Initial Comment:
The documentation for libssh2_poll says the semantics are like poll(2).  However \
poll(2) accepts a -1 timeout, which means to wait indefinitely.  libssh2_poll  does \
not correctly handle a -1 timeout.  It seems like the only way to indicate an \
indefinite wait is to pass a really large timeout to libssh2_poll.  I think either \
the documentation should mention that libssh2_poll differs from poll(2) in this way, \
or a -1 timeout should be supported as meaning wait indefinitely.

Currently, if you look in libssh2_poll code, it performs arithmetic on \
timeout_remaining without first checking to see if it's negative.  I can submit a \
patch to make libssh2_poll support -1 like poll(2) if you'd like.
