[Libssh] undefined refs linking to server functions FIXED

[Matt Lawson]

Ha!  Fixed it!  As usual the solution came to me once
I stopped pounding the keyboard and walked away for a
while...

server.h is missing the sequence:

#ifdef __cplusplus
extern "C" {
#endif
...
#ifdef __cplusplus
} ;
#endif

This sequence is present in other files such as
libssh.h and sftp.h, that's why those worked with my
app which is, obviously, written in C++.  So that
should prolly be added to server.h.

One other unrelated consistency I ran across: 
ssh_options_new() is in libssh.h but
ssh_options_free() is in priv.h which describes itself
as "[stuff] the user app shouldn't have to [mess
with]".  So I'm unclear as to if I'm supposed to be
allocating SSH_OPTIONS dynamically or just use the
stack.

Keep up the good work!
