If needed is bigger than the highest power of two or a which fits in an
integer we will loop forever.

04f1d950b9 session: Fix a possible use after free in ssh_free(). 
We need to cleanup the channels first cause we call ssh_channel_close()
on the channels which still require a working socket and poll context.

Thanks to sh4rm4!

558b53a856 session: Cleanup timeout functions and fix packets termination. 
It is possible that we get unrelated packets while waiting for
termination, thus waiting indefinitely. As a workaround we have to
check the user-supplied timeout.
Also cleaned up ssh_blocking_flush, which was using the timeout in a
bogus manner (resetting the timeout after each check).

6f650a61ca poll: resolve use-after-free + inconsistent callbacks call 
This code was weird in the first place. I suspect my change will break something else
(probably the appcode that needed it). ssh_poll_ctx_free is not a good
place to send exception callbacks imho.

edb03bd224 Fixed ssh_scp_write so it works when doing recursive copy 
There where two issues with ssh_scp_write:
1) It did not write a status message after the last write and OpenSSH
   would then give up after the write finished.
2) OpenSSH would sometimes write a status message, after near ends write.
   If scp_write didn't handle it, and subsequent status message. The remote
   window would shrink to zero and ssh_channel_write would start returning 0.
