9c10ddae3b GUACAMOLE-470: Fix incompatible pointer type warning under older GCC. 
Older versions of GCC (prior to 5.1) emits an "incompatible pointer

changed in GCC 5.1, and this patch adds explicit casts to remove the
warning under older GCC.

d33bd8deff GUACAMOLE-384: fixing segfault during ssh disconnect 
Root Cause:
See the core dump and Valgrind report posted on Jira. guacd was reading a ssh terminal which had been freed. When a ssh connection is terminated, guac_ssh_client_free_handler() will be called from guacd_exec_proc() -> guac_client_free() with pointer client->free_handler. In guac_ssh_client_free_handler(), when ssh_client->term is freed, ssh_client->client_thread may still be using the ssh_client->term. It causes the crash reported in this bug.

The stack trace exposing the problem can be found by running guacd under Valgrind with a ssh test script. The test script repeats doing ssh login and logout for 5000 times.

Solution:
In guac_ssh_client_free_handler(), before calling guac_terminal_free(ssh_client->term), close the stdin pipe of the terminal to stop reading the pipe with guac_terminal_read_stdin() in ssh_input_thread(). So that ssh_input_thread() can be terminated in this case. Call pthread_join() to wait for ssh_client_thread() terminating before freeing the terminal.

Add a new function guac_terminal_stop() to close the pipe and set the fds to invalid (-1). Call it in guac_ssh_client_free_handler() and guac_terminal_free().

Checking the client running state in ssh_input_thread() and ssh_client_thread() to make sure they can be terminated when the client is stopped in guacd_exec_proc() by another thread.

Test:
- Confirmed ssh connection works normally.
- Observed the child process of guacd exits when ssh connection is terminated.
- Reran the ssh test script. Observed no crash.
