Most notably, -Wdeclaration-after-statement. This and -Wpointer-arith

hypotenuse -> squared length of the hypotenuse

-Wwrite-strings is useful to detect code where string literals and e.g. alloc'd
strings are used side-by-side, potentially creating dangerous situations, or to
find uses of old, non-constified APIs. However, enabling it would still flood
the log with too many warnings. Also, GCC wrongly warns for initializations of
char arrays.

Most differences are handled with function parameters, except that one instance
checked SpriteProjectile[i].spawns for being >0 instead of >=0. The factored
function always checks for >=0.

uhypsq calculates the hypotenuse using unsigned multiplication. This is
permissible since for arbitrary int32s a and b, the following holds in
two's complement arithmetic:
(int32_t)((uint32_t)a * b) == (int32_t)((int64_t)a * b)
("Signed and unsigned multiplication is the same on the bit level.")
This fixes various overflows where wall lengths for walls of length > 46340
are calculated, but does not rid us of other overflows in the same vein
(usually dot products between vectors where one point is a wall vertex and
the other a position in a sector).

The latter shows that "int32_t ksqrt(int32_t)" also copes with values in the
range INT32_MIN..-1, effectively interpreting them as uint32_t (i.e. adding
2**32). However, this should not be relied on from CON.

Arrays inside structs must not be accessible, since they're not bound-checked

to write accessor functions later.

That is, "clang -ftrapv" builds don't abort almost immediately after entering
a level.
There are various classes of overflow bugs, needing different handling:
- Some texture mapping code was written with signed integer wrapping semantics
in mind. In some places, we're able to get away with unsigned casts.
- sometimes, we really need a wider range, like when calculating distances or
dot products
- negating INT_MIN. Here, we cast to int64_t temporarily. Note that if the
result is 32-bit wide, no 64-bit code may actually need to be generated.
- shifting into a signed integer's sign bit. We cast to uint32 here.
- in hitscan(), at the "abyss crash prevention code" comment, it's clearly
the other code that is better...
This is not merely done for pedantry, but rather makes it easier to track down
overflow bugs having a real impact on the game.

special keys like ENTER or BACKSPACE in the OSD, probably more...
In build/Makefile.shared, we now have logic to autodetect an SDL2 installed
in /usr/local, however OS X and Wii builds follow other Makefile code paths,
it seems. Note that the matching SDL2_mixer must be used then, too.
In source/jaudiolib/src/driver_sdl.c, change the #includes from <SDL/SDL_xxx.h>
to "SDL_xxx.h". SDL wiki says this is the most portable way, hopefully this
doesn't break builds for anyone.

It's time to replace some int32s with 64-bit ints in core engine functions.
The problem is that for example, the dot product is taken between vectors that
may be the difference between two arbitrary points in a sector, so even if one
sticks to the "no blue walls" rule, that doesn't guarantee freedom from
overflows.

Also,
- don't strip const when passing the char ptr to it and a couple more
instances in game.c
- use g_netPort when -connect parameter doesn't have a port suffix (":XXXX"),

eduke32 -port 1700 -connect localhost
is the same as
eduke32 -connect localhost:1700

The GAMESTATE one has to be carried out twice, first on the data from
xd3_encode_memory, and then with the compressed data (because it might have
increased in size, though this is very unlikely). The MOVE check is
similar, though there, failure of the first check implies corrupt memory
(which is why we're Bassert'ing that condition).
Currently, the overflow on GAMESTATE sending happens when switching to a
different map.

New Wii control defaults for the Wii Remote + Nunchuk and the Classic Controller. This includes new code added just so that the Home key brings up the menu in-game, reducing the need for a USB keyboard.
On the technical side, raw joystick access (comparable to what is available for keyboard and mouse) is now present in jmact, on the game side. (added: joystick.[ch])
Using this new raw joystick access, I replaced tueidj's hack to map A and B to LMB/RMB and D-Pad Up/Down to the scrollwheel.
I made the menus more friendly to mouse and joystick browsing by adding and unifying checks and clears for various buttons and gamefuncs. In fact, the majority of the time spent on this commit was tracking down problems that appeared with the factoring and trying to understand the menu system and the way input checks are precariously executed.
In addition, "Press any key or button to continue" now truly means what it says.
As a result of incorporating proper raw access into control.c instead of it directly accessing the implementaiton, the program *may* no longer be affected by joystick input when it is out of focus. This follows the pattern set by the mouse, and I think this is a positive change.
A small bonus: In the classic/old keyboard preset, the key for Show_Console has been changed from '`' to 'C' because '`' is taken by Quick_Kick.

Usage is from 3D mode only. When a sector (or wall) is committed to the
clipboard, it (or the wall's sector) is saved, and is subsequently used
when auto-aligning [;-ENTER] another sector's ceiling or floor against the
reference one's. This temp. sector is reset on any structurally modifying
operation except setting first walls; also, aligning extended ceilings or
floors is impossible as they use .*xrepeat internally.
The auto-alignment does not change picnums (this can be accomplished with
the ['+ENTER] combination), but copies the orientation bits 2^{2..6} to the
alignee. Afterwards, if the reference is relative-aligned, it tweaks them,
so that every case where the two firstwalls are either parallel or perpendi-
cular is handled correctly.
It does not yet calculate the panning values.

This is done by kopen4loadfrommod'ing and immediately closing the file

On my system, times were like 0.12 ms, 0.2 ms and 0.5 ms for each

I experienced the following on Windows XP: a few openfrompath() -->
findfrompath() calls were taking enormously long (4.5 secs) to complete, having
been passed a file name like "//bla/qwe.asd". My guess is that Windows then
tried to interpret these as a network FS path in access(), and the 4.5 secs
represents a timeout value.

The first means that the expensive (~0.5 ms) SHGetFileInfo() calls won't inter-
fere with smooth gameplay, but files that are opened only at game-time like
sounds won't be checked. The second means that there are now less false
positives, i.e. warnings about files that would be found due to the
check-all-{upper,lower} hack.
