Unix Plink: stop zeroing out the terminal size in pty-req.

Browse Source 
I noticed today that when you use Unix Plink interactively, to run a
tty session on a remote host starting from a local tty, it doesn't
copy the local terminal size into the "pty-req" channel request.

It looks as if this is a bug introduced in 2ca0070f8, when I broke up
ssh.c. Before that, the monolithic Ssh init procedure set
ssh->term_width and ssh->term_height from the Conf you passed in.
Afterwards, variables of the same name existed in both ssh.c *and*
ssh2connection.c (the former so that it can buffer window-size changes
before a connection layer yet exists to pass them on to), but somehow,
*neither* source file remembered to initialise them from the Conf.

Fixed by reinstating the initialisation in ssh.c. (For the same reason
as above: you want the values in Conf to be overwritten if the window
size changes between ssh_init and ssh2_connection_new.)
