If it helps, I used libssh in a multi-threaded application without
calling ssh_threads_set_callbacks() or linking libssh_threads.
In fact, I never even read this part of the libssh documentation before
today. :)

The main/original thread of the application calls ssh_init() and then
spawns off one additional thread that makes all the other libssh calls.
The freeing of resources and ssh_finalize() are done back in the
original thread after this other thread has finished.

So far there have been no issues that I can attribute to using it this way.

We're running on Linux (RedHat 6.x) and using libpthread.
