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.

And const them appropriately. Also remove #if 0'ed code related to an MSVC
pragma.

Meaning that only *ettsprite[THISACTOR] makes sense from CON. It did before
too, because .tspr was set before each event run (and not before all runs),
only that it was never nulled, which was kind of untidy.

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

The m32script variable 'showrespawn_always' toggles whether the respawned picnum
is shown unconditionally instead of only when aimed at (and locked onto the
RESPAWN sprite) in 3D mode.
Cool idea by Micky C.
NOTE: sometimes doesn't work because of a bug in the m32script interpreter.

Pass types via ffi.typeof() instead of declaring them in the
global namespace when possible.

Use a new flag to mark hard-coded enemies, not SPRITE_BADGUY.
This fixes an issue where in E1L4, a pigcop would appear in the area
you have to crawl under shrunk. Thanks to LLCoolDave1 for pinpointing
the range of relevant revisions.

Whenever it should be not, STRIP is set to the empty string.
This fixes the Lunatic RELEASE=1 build.

The pixel doubling now only applies to the area where the world scene is drawn,
i.e. it may be smaller than the physical screen / WM window size. The optimized
version is slightly faster than for non-doubled pixels for me (optimized build),
but see code for caveats. Some other minor issues:
- won't work when the world is drawn from demo cameras (and offscreen, but that
matters less)
- will leave a few pixels empty when running with x resolutions not evenly
divisible by 4

In CON, the bit is still always cleared for user-defined gamevars.

- more predefined vars
- fix recursive states and ones with a stray "else" before the end
