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.

3c7a09f52b GUACAMOLE-400: Fix guacd crash when ssh key fails 
Root Cause:
In the ssh library of guacd, function ssh_client_thread(), when guac_ssh_get_user() fails to load private key for ssh authentication, it will return NULL. In this case, the subsequent call to guac_common_ssh_create_session() with parameter 'user=0x0' will cause guacd crash in function guac_common_ssh_authenticate() by accessing 'user->username'.

Solution:
- Update the comment of function guac_ssh_get_user() to document that NULL will be returned if fails to import key for the user.
- In function ssh_client_thread(), verify the return of guac_ssh_get_user(). If ssh_client->user is NULL, return NULL.

Test:
- Configured a ssh app with an encrypted private key and a wrong passphrase.
- Ran the ssh app from web portal and observed guacd crash.
- Applied the fix and reran the ssh app. Observed no crash.
