This makes unnecessary to call ssh_init() when the library is dynamically loaded. Also removes the threads shared library. The used threads implementation is chosen in configuration time, changing the ssh_threads_get_default() depending on the available threads library. Internally, it is expected a threads implementation providing: - void ssh_mutex_lock(void **mutex); - void ssh_mutex_unlock(void **mutex); - struct ssh_threads_callbacks_struct *ssh_threads_get_default(void); and a crypto implementation providing: - int crypto_thread_init(struct ssh_threads_callbacks_struct *user_callbacks); - void crypto_thread_finalize(void); This adds internal threads implementation for pthreads and noop.
