tty prompting fix and DUMPLOG of prompts+answers

Update DUMPLOG's message history to include player responses to
most queries.  For tty, both getlin() and yn_function().  For other
interfaces, only yn_function() is covered.  (It's intercepted by a
core routine that can take care of the logging; getlin() isn't.)
Also includes saved messages from previous session(s), for the
interfaces which support that (tty), to fill out the logging when
a game ends shortly after a save/restore cycle.

The tty interface was using pline() to display prompt strings.
Having 'MSGTYPE=hide "#"' or 'MSGTYPE=hide "yn"' in .nethackrc
would suppress many prompt strings (in the two examples mentioned,
entering extended commands or the vast majority of yes/no questions,
respectively) and generally lead to substantial confusion even if
done intentionally, so switch to putstr(WIN_MESSAGE) instead.
