We don't require anything newer than libssh2 0.16, and lib/ssh.c has #ifdefs
for HAVE_LIBSSH2_SESSION_BLOCK_DIRECTIONS for that reason.

I do think however that inofficial libssh2 builds like 0.19.0-20080814 could
be subject to some "between versions" problems and I really would recommend
against using such releases in a distro. The libssh2 project makes
"real" releases for such purposes and I don't think you'll experience these
problems with one of them...
