0b93de904a Add 'const' to the game_params arguments in validate_desc and
new_desc. Oddities in the 'make test' output brought to my attention
that a few puzzles have been modifying their input game_params for
various reasons; they shouldn't do that, because that's the
game_params held permanently by the midend and it will affect
subsequent game generations if they modify it. So now those arguments
are const, and all the games which previously modified their
game_params now take a copy and modify that instead.

0e8a375814 Forgot to add the new 'const' in the unfinished subdirectory. Oops.

73daff3937 Changed my mind about midend_is_solved: I've now reprototyped it as
midend_status(), and given it three return codes for win, (permanent)
loss and game-still-in-play. Depending on what the front end wants to
use it for, it may find any or all of these three states worth
distinguishing from each other.

(I suppose a further enhancement might be to add _non_-permanent loss
as a fourth distinct status, to describe situations in which you can't
play further without pressing Undo but doing so is not completely
pointless. That might reasonably include dead-end situations in Same
Game and Pegs, and blown-self-up situations in Mines and Inertia.
However, I haven't done this at present.)

2efc77d2fd Fix warnings generated by gcc 4.6.0 about variables set but not
thereafter read. Most of these changes are just removal of pointless
stuff or trivial reorganisations; one change is actually substantive,
and fixes a bug in Keen's clue selection (the variable 'bad' was
unreferenced not because I shouldn't have set it, but because I
_should_ have referenced it!).

980880be1f Add a function to every game backend which indicates whether a game
state is in a solved position, and a midend function wrapping it.

(Or, at least, a situation in which further play is pointless. The
point is, given that game state, would it be a good idea for a front
end that does that sort of thing to proactively provide the option to
start a fresh game?)

33be388d41 Take out some lurking "nullgame" holdovers from unfinished puzzle
source files, in case they cause trouble. Spotted by Lee Dowling.

fe1b91ac49 Since the lack of this has caused portability issues in the past:
add "-ansi -pedantic" to the main Unix makefile, and clean up a few
minor problems pointed out thereby.

a7431c0b7c New infrastructure feature. Games are now permitted to be
_conditionally_ able to format the current puzzle as text to be sent
to the clipboard. For instance, if a game were to support playing on
a square grid and on other kinds of grid such as hexagonal, then it
might reasonably feel that only the former could be sensibly
rendered in ASCII art; so it can now arrange for the "Copy" menu
item to be greyed out depending on the game_params.

To do this I've introduced a new backend function
(can_format_as_text_now()), and renamed the existing static backend
field "can_format_as_text" to "can_format_as_text_ever". The latter
will cause compile errors for anyone maintaining a third-party front
end; if any such person is reading this, I apologise to them for the
inconvenience, but I did do it deliberately so that they'd know to
update their front end.

As yet, no checked-in game actually uses this feature; all current
games can still either copy always or copy never.

81e3a145bf Remove the check for disconnected pieces; it's over-general and
triggers on a perfectly connected piece shaped like an inverted T.
