Fix squeaky board creation segfault
If a trap is created on top of another trap, maketrap reuses
the trap struct in place, instead of deleting and recreating it.
If a squeaky trap was created on top of another trap, maketrap
first set the trap type to squeaky board, and then tried to
look through all squeaky boards on the level, to determine
what note the new trap should play. Unfortunately, the union
with the trap note most likely contained a rolling boulder
coordinate or something else outside the 12 note range, so
then the tavail-array lookup would cause a segfault.

VA_DECL/VA_END usage
Make the variadic functions look more like ordinary code rather than
have the function opening brace be hidden inside the VA_DECL() macro.
That brace is still there, but VA_DECL() now needs to be followed by
a visible brace (which introduces a nested block rather than the
start of the funciton). VA_END() now provides a hidden closing brace
to end the nested block, and the existing closing brace still matches
the one in VA_DECL().
Sample usage:
void foo VA_DECL(int, arg) --macro expansion has a hidden opening brace
{ --new, explicit opening brace (actually introduces a nested block)
VA_START(bar);
...code for foo...
VA_END(); --expansion now provides a closing brace for the nested block
} --existing closing brace, still pairs with the hidden one in VA_DECL()
This should help if/when another round of reformatting ever takes place,
and also with editors or other tools that do brace/bracket/parenthesis
matching.
I had forgotten that there were variadic functions in sys/* and ended
up modifying a lot more files than intended. The majority of changes
to those just inserted a new '{' line so that revised VA_END()'s '}'
won't introduce a syntax error. A couple of them needed VA_END() moved
so that local variables wouldn't go out of scope too soon. Only the
Unix ones have been tested.

fix mdig_tunnel impossibility
Reported by the keymasher: "stone at (48,8) is undiggable". Bigroom 4

Undiggable trees were supported on arboreal levels (where their terrain
type is STONE rather than TREE), but not elsewhere. Monster movement
uses IS_ROCK(), which is true for TREEs, but may_dig() uses IS_STWALL(),
which is false for TREEs so doesn't consider the location as being of
interest and fails to disallow digging. But mdig_tunnel() bypasses
may_dig() and tests the NONDIGGABLE bit directly, disallowing digging.
(If this sounds confusing, it's a stroll in the park compared to the
code itself. Apologies for the mixed metaphore.)
Digging away a secret corridor could leave rocks, which doesn't make
a whole lot of sense. Now a monster's dig attempt will reveal the
location as a corridor instead.
This also moves an assignment out of a macro invocation where it was
inviting trouble if that macro gets modified. And reorganizes an 'if'

X11 lint suppression
Suppress close to 400 warnings generated by gcc on the win/X11/*.c code,
most due to -Wwrite-strings which makes string literals implicitly have
the 'const' attribute. (Since modifying a string literal results in
undefined behavior, that is an appropriate check to have enabled, but
it can be troublesome since string literals have type 'char *' and code
that uses them that way is correct provided it avoids modifying them.)
113 warning: initialization discards qualifiers from pointer target type
127 warning: assignment discards qualifiers from pointer target type
29 warning: passing argument discards qualifiers from pointer target type
109 warning: unused parameter
12 warning: comparison between signed and unsigned
The nhStr() hack casts to 'char *', explicitly removing 'const', for
situations where it isn't feasible to make code directly honor const.
The vast marjority of uses are for the second parameter to XtSetArg(),
which is a macro that actually performs an assignment with the second
argument rather than passing it in a function. It takes values like
'XtNtop', which doesn't need to be altered (although in many places I
changed that to nhStr(XtNtop) for uniformity with the surrounding code,
and 'XtNbottom', which does need to have the extra const stripping to
avoid a warning. Go figure.
The nhUse() hack actually uses its argument in a meaningless way if the
code is compiled with FORCE_ARG_USAGE defined. When GCC_WARN is defined,
FORCE_ARG_USAGE will be enabled if it hasn't been already. Example:
/*ARGUSED*/
int foo(arg)
int arg; /* not used */
{
+ nhUse(arg);
return 0;
}
The extra line will expand to ';' when FORCE_ARG_USAGE is not defined
or too
nhUse_dummy += (unsigned)arg;
when it is. I figured direct assignment might lead to a different
warning by some compilers in a situation like
nhUse(arg);
nhUse(otherarg);
where the first assignment would be clobbered by the second, and using
bitwise operations or safer '+= (arg != 0)' would most likely generate
more non-useful code. Some tweaking might turn out to be necessary.
Groundwork for cleaning up the X11 sources, where gcc with the option
settings specified in the OSX hints file currently generates close to
400 warnings for win/X11/*.c.
lint.h is included by hack.h, and I've moved the debugpline stuff from
the latter to the former to hide it better. (By rights it belongs in
debug.h or something of the sort, but I didn't want to go that far.)
Makefile and project dependencies need to catch up.
nhStr() hides a cast to char *, and is intended to by used on string
literals where it isn't feasible to maintain the 'const' attribute.
(A pernicious problem with X11 code, where the include situation can
become very convoluted, and many, MANY string literals are hidden
behind macros to look like keyword-type tokens.)
nhUse() can be used to force a fake usage on something which triggers
an unused parameter warning. There are a 6 or 8 or 10 places in the
core code where that applies, but so far I have't touched any of them.
There's a tradeoff since it will result in some worthless code being
generated and executed, but is much simpler than tacking on compiler-
specific workarounds like '#pragma unused' or gcc's __attribute__ hack.
