My new programming style is branch hints. All non-confusing branches
must be hinted when I can be bothered. It's faster, sometimes, maybe.
Also, start trying to use more signed sizes in at least some of the
places where it makes sense. Unsigned sizes are surprisingly
error-prone!

- As much as possible avoid dragging system headers into translation
units. This should avoid namespace pollution and, hopefully, speed up
builds a little bit.
- Avoid leaning on the UCRT so much on Windows - prefer native win32
calls and native file handles except where doing so is inconvenient
(in particular, for stat(), which we might try and replace later).
- Also, switch from SystemFunction036 to ProcessPrng on Windows. This
requires us to generate a stub for bcryptprimitives.dll because
Microsoft haven't bothered to provide a link library, but the function
is better-documented and seems to be a more direct under-the-hood call
as well. Apparently it's what's used by the major web browsers these
days, which seems like a good indication it's stable and trusted.
- Lastly, remove a bunch of functions and macros and stuff that weren't
actually being used. It seems good to try and keep the scope of
OS-dependent stuff relatively contained and only add to it when
actually required.

Suggested by bill. Having something semantically pointer-sized that's
only ever used for stuff that's always 32-bit doesn't really make sense.
Note that I intentionally did not add a copyright line for myself in
hud.c because, I mean, come on. I'll just say I waive any claim to that
tiny trivial change.

This fixes a crash in later L4D2 versions caused by the fact we were
unknowingly hooking Key_Event already. Now we hook it all the time on
purpose.

Because why not.

Nothing really works yet, but at least test.h and fastspin are fixed and
some of the issues with RTTI and libdl and stuff are maybe kind of
sorted, subject to more testing later.
The main issue now seems to be the cvar interface not quite lining up
and crashing pretty much immediately. That'll probably take a lot more
debugging to figure out, which likely still won't be a priority for
quite a while.

A lot of this is random WIP from a while back, at least a month ago, and
is being committed now to get it out of the way so that other patches
can be brought in and integrated against it without causing headaches.
Also rolled into this commit is a way to distinguish plugin_unload from
exiting the game. This is required for another soon-to-be-integrated
feature to avoid crashing on exit, and could in theory also be used to
speed up unloading on exit in future. While we're at it, this also
avoids the need to linearly scan through the plugin list to do the
old branch unloading fix, because we can.
Rough summary of the other smaller stuff I can remember doing:
- Rework bitbuf a bit
- Add some cryptographic nonsense in ac.c (not final at all)
- Introduce the first couple of "chunklets" libraries as a sort-of
subproject of this one
- Tidy up random small bits and bobs
- Add source for a small keypair generation tool
- Rework democustom to be very marginally more useful

- Use const in more places where it makes sense - not absolutely
everywhere because it can get a bit annoying
- Make all the instruction search loops a bit more readable by casting
the function pointer into a temporary variable to loop over
- Add a few more doc comments and fix a typo or two
- Make that RTTI thing flexibly-sized, finally
- Don't include gamedata.h in vcall.h for no reason; consequently
include gamedata.h in a bunch of places where it was implictly pulled
in before
- Fix dbg_toghidra() and ent_getedict() having mismatched return types
between their headers and respective source files
- Remove that one broken, hacky, secret Portal non-feature that probably
nobody even ended up using; it can be implemented properly later if
required

This still isn't totally complete, or used anywhere yet, but it's been
sitting here for literally months, so it might as well get committed so
there's one less thing to deal with later.

Another big one. Here's a list of things:
- Since the upcoming C23 standardises typeof(), use it as an extension
for the time being in order to allow passing arbitrary types as
macro/codegen parameters. It wouldn't have been a big leap to do this
even without standardisation since it's apparently an easy extension
to implement - and also, to be honest, this project is essentially glued
to Clang anyway so who cares.
- Likewise, bool, true and false are becoming pre-defined, so
pre-pre-define them now in order to get the benefit of not having to
remember one header everywhere.
- Really ungodly/amazing vcall macro stuff now allows us to call C++
virtual functions like regular C functions. It's pretty cool!
- Events can now take arbitrary parameters and come in two types:
regular events and predicates.
All this makes the base code even uglier but makes the feature
implementation nicer. In other words, it places more of the cognitive
burden on myself and less on other people who might want to contribute.
This is a good tradeoff, because I'm a genius.

Committer's note: this is somewhat adapted from Bill's original code,
written a while back, but he gets full credit for actually doing the
hard part.

Some of the alias stuff was kind of stolen from earlier figuring-out
Bill did. More Bill code is also on the way. :^)
