89da2ddf56 Giant const-correctness patch of doom!
Having found a lot of unfixed constness issues in recent development,
I thought perhaps it was time to get proactive, so I compiled the
whole codebase with -Wwrite-strings. That turned up a huge load of
const problems, which I've fixed in this commit: the Unix build now
goes cleanly through with -Wwrite-strings, and the Windows build is as
close as I could get it (there are some lingering issues due to
occasional Windows API functions like AcquireCredentialsHandle not
having the right constness).

Notable fallout beyond the purely mechanical changing of types:
 - the stuff saved by cmdline_save_param() is now explicitly
   dupstr()ed, and freed in cmdline_run_saved.
 - I couldn't make both string arguments to cmdline_process_param()
   const, because it intentionally writes to one of them in the case
   where it's the argument to -pw (in the vain hope of being at least
   slightly friendly to 'ps'), so elsewhere I had to temporarily
   dupstr() something for the sake of passing it to that function
 - I had to invent a silly parallel version of const_cmp() so I could
   pass const string literals in to lookup functions.
 - stripslashes() in pscp.c and psftp.c has the annoying strchr nature

42c592c4ef Completely remove the privdata mechanism in dialog.h.
The last use of it, to store the contents of the saved session name
edit box, was removed nearly two years ago in svn r9923 and replaced
by ctrl_alloc_with_free. The mechanism has been unused ever since
then, and I suspect any further uses of it would be a bad idea for the
same reasons, so let's get rid of it.

34f747421d Support for Windows PuTTY connecting straight to a local serial port
in place of making a network connection. This has involved a couple
of minor infrastructure changes:
 - New dlg_label_change() function in the dialog.h interface, which
   alters the label on a control. Only used, at present, to switch
   the Host Name and Port boxes into Serial Line and Speed, which
   means that any platform not implementing serial connections (i.e.
   currently all but Windows) does not need to actually do anything
   in this function. Yet.
 - New small piece of infrastructure: cfg_launchable() determines
   whether a Config structure describes a session ready to be
   launched. This was previously determined by seeing if it had a
   non-empty host name, but it has to check the serial line as well
   so there's a centralised function for it. I haven't gone through
   all front ends and arranged for this function to be used
   everywhere it needs to be; so far I've only checked Windows.
 - Similarly, cfg_dest() returns the destination of a connection
   (host name or serial line) in a text format suitable for putting
   into messages such as `Unable to connect to %s'.

46bfde32e8 Initial checkin of a native Mac OS X port, sharing most of its code
with the Unix port and layering a Cocoa GUI on top. The basics all
work: there's a configuration panel and a terminal window, the
timing interface works and the select interface functions. The same
application can run both SSH (or other network) connections and
local pty sessions, and multiple sessions in the same process are
fully supported.

However, it's horribly unfinished in a wide variety of other ways;
anyone interested is invited to read README.OSX and wince at the
length and content of its `unfinished' list.
