This enables ART animations to take effect on voxels in classic, voxels and models in Polymost, and models in Polymer.

- With SDL layer, pass argv and argc directly and get rid of _build* ones.
- Add tilesiz* to dynsymlists.

This fixes an update issue: start EDuke32 without warping to a map in Polymost,
change to classic, and change to Polymost again. The OSD background will be
displaced.

If m32script gamevar "move_by_one" is nonzero, the some keys move the
"player arrow" by increments of 1:
- Without SHIFT: LEFT/RIGHT absolute x, DOWN/UP absolute y, A/Z absolute z.
- With SHIFT: DOWN/UP (unbounded!) horiz, LEFT/RIGHT angle.
This can be useful to debug renderer bugs that show a high sensitivity to the
exact location ("are transient in space").

Face- and wall-aligned sprites are drawn using the wall routines in BUILD.
However, the per-x-screen-coordinate distance (swall[]) is calculated in a way
that potentially incurs great precision loss (for example 5 bits for
xdimen=1280, yxaspect=65536). This leads to the starting (top) vertical texture
coordinate possibly wrapping to large values, leaving an unsightly "stray line"
on top of the sprite from certain viewing angles/horiz values.
The approach to fix it has two parts: first, the distance is calculated using
float values, preventing the precision loss. Because this doesn't fully prevent
the unwanted lines, the texture coords are clamped to the mininum and maximum
(0 and UINT32_MAX respectively) when calculating them for sprites.
Note that stray lines may still appear at the *bottom* of sprites under certain
circumstances, for example when viewing at a y-flipped sprite from above.
These should be less noticable in real-world usage though.
The feature is guarded by a macro HIGH_PRECISION_SPRITE in case using floating
point or 64-bit integers is undesirable/impossible on some platforms.

That is, first check if the sprite is in the game world and then if it
already has the desired sector or status number. This doesn't change anything
in our codebase, since the return values of these functions are never examined.

The usual: declare locals more tightly, const-qualify them where it helps
readability, remove dead code...

Most of them are already aligned to their natural boundaries, so lowering
the alignment to 1 byte can only worsen things by making the C compiler
generate poorer (unaligned access) code for some platforms.
The layout of structures is not specified by the C Standard, but is rather
given by a particular platform + toolchain's ABI (application binary interface).
Most ABIs follow the expected pattern "alignment of scalars is their size,
alignment of arrays is that of its element type, alignment of structs is the
maximum alignment of its members". A couple of links to particular ABIs are
given in build.h.
Problems are expected with archs that care about unaligned access when a pointer
to a non-packed struct is taken that resides in a packed aggregate, but these
uses should be weeded out (I'm not sure if there are any in our codebase).
The following types are affected, only hitdata_t changes its size:
sectortype, walltype, spritetype, spriteext_t, spritesmooth_t,
struct validmode_t, picanm_t, palette_t, vec2_t, vec3_t, hitdata_t.

Its only use is to have a actor -> tsprite mapping for the EVENT_ANIMATESPRITE
event and .tspr will be set before it is run.

Whether a sprite is considered for texel-hitscan is determined on the base
tile number, not the individual animated tile numbers.

One use was in determining the ray vector for the mouse-aiming hitscan
in the editor. Unfortunately, the change doesn't make it any less broken
in Polymost, even if the two instances were out of sync.

If enabled, dragging wall vertices will correct the xrepeat after the
mouse button is released, so that the pre-drag absolute stretching is
restored.

- Run it twice, since the first one is wrong.
- Warn when attempting to align based on a top-oriented wall. When the
sequence of walls to align has "windows", only the bottom parts will
be correct.
- Make the modifiers actually useful:
* Pressing SHIFT aligns at most one wall, remove the old CTRL modifier.
* The rest is as before: ALT makes the walls have (approximately) equal
texture stretching, ['] (quote) aligns the immediate TROR-nextwalls.

Also, factor out 2x dup'd code of insertsprite() into do_insertsprite()
and add searchwall-displaying code into package/samples/a.m32.

Also, add another flag, signifying that from the editor, also the
"lastwall"s (i.e. the CCW-linked points) should get collected. This is
to signal the editor that their wall lengths should be displayed, too.

- Stop using memcache on some other failure paths, particularly when
failing to read from the on-disk texcache.
- Factor out cache reading code (3x).
- Fix endianness issues affecting big-enadian systems (one introduced by
r3382, one existing before). Comment each B_LITTLE32 with whether we're
converting from native to on-disk (little) endianness or back.

The SDL and Windows layers had slightly different code: the latter would
dereference a NULL pointer if stdout.txt failed being write-opened.
