[bug] random Invalid argument error returned by ssh_options_set()

[sunziping2016]

I added debug information to check which ssh_options_set() on earth returned the random error. I found it was always this line.

sshping/src/sshping.cxx

Line 544 in b2e7c40

_CKERR(ssh_options_set(ses, SSH_OPTIONS_TIMEOUT, &contim));

I searched the libssh documentation, and it stated SSH_OPTIONS_TIMEOUT and SSH_OPTIONS_TIMEOUT_USEC should be of type long¹. I've got a 64-bit machine, so typically, int is 4-byte long, whereas long is 8-byte long on my machine. So I suspected the mismatched integer type in L78 and L82 is the root cause. I haven't verified it. Thks!

sshping/src/sshping.cxx

Lines 78 to 82 in b2e7c40

	int zero = 0;
	int verbosity = 0;
	int char_limit = 0;
	int time_limit = 0;
	int contim = 10;
