This will be mostly useful for skipping cutscenes in Left 4 Dead games.
It may work in other games, but probably won't really be as useful.
Committer's note: this was adapted a fair bit from woz's original code,
hence the joint copyright, but he did most the hard work of figuring out
how to get this deep into the engine's call stack. Thanks!
bill also provided a fair bit of help figuring out missing gamedata and
fixing compatibility with L4D2 2147 and later. Also thanks!

- Add a couple of overdue -Werrors that make life easier
- Reshuffle cc/ld flags a bit, mainly around -fuse-ld=lld

This will save users having to install the VS runtime in order to load
the plugin. Turns out there was very little to implement to make this
work.
Turning off stack probing might cause spooky outcomes further down the
line but we'll burn that bridge when we get there.

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

This was clumsily added in 1c4318331663b152b0b298bd2c9e5c971506a86b as a
test case for code I was writing at some point but has not been included
in the repository yet. This means the 0.6 tag is broken for anyone
trying to build from source unless this change is cherry-picked on top.
Lesson learned: keep the working tree clean!

This is kind of a breaking change but the other code was obviously never
released or relied on by anyone - it will be pushed at the same time as
this in fact. It still seems worth having the original committed
separately to show the progression of development of the feature,
however. Technically the standalone vote cooldown resetting could also
be added back if ever desired however there doesn't seem to be that much
of a use case for that at the moment.
This feature ought to be a lot more convenient now as it allows for
resetting back to a set starting point no matter where the player is in
a run. It isn't universally useful as All Campaigns Legacy solo runs
require switching to a different type of server and Main Campaigns co-op
runs require restarting the game after Swamp Fever to work around the
god mode bug, however it is still useful in a good few situations.
Unfortunately this turned out to be pretty complex to implement, first
requiring a bunch of interop with valve's rather wacky KeyValues stuff,
and then requiring a bunch of especially difficult reverse engineering
of L4D1 v1.0.0.5 because it doesn't use said KeyValues stuff and does
something else completely different instead.
A side effect of all this work is that the nag removal hack is now part
of the KeyValues stuff in kvsys.c, which is kind of a comfier place for
it than just kind of dumped in the middle of sst.c.

In most versions of L4D2, players cannot call a vote (e.g. switch
campaign, change difficulty, restart campaign) more than once every 3
minutes. This makes resetting on a first map a pain, usually requiring
reloading the map to reset the vote state.
This new sst_l4d_vote_cooldown_reset command empties the list of
structures tracking vote callers, allowing all players to vote again
immediately. This should make resetting runs a lot easier on versions
without unlimited votes.

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.

This is for somewhat later. I'd always planned to use it - it existed
already in earlier private repos, in fact. I just didn't bother to
import it here in case it wouldn't actually be needed, but with the way
current plans are going, it's definitely going to be needed, so here it
is.

Copyright note: the stuff Bill wrote is all still in the other file.
|
|
Also centralise NEXT_INSN macro, into its own header at least for now.
|
|
Some of the alias stuff was kind of stolen from earlier figuring-out
Bill did. More Bill code is also on the way. :^)

Currently only works in 3420 and 5135 and uses hardcoded offsets with a
byte pattern sanity check. Future work includes making it more widely
compatible, and also doing the crazy thing I wanted to do but gave up on
wherein the actual textures and stuff get patched in memory to sync up
all the colours.
Oh also, a couple of vtables were erroneously made executable, so I went
ahead and fixed that while I was at it.
|

This was a lot more code than expected, but it might be finally close to
time to release the next beta...
We'll see if any more rabbit holes present themselves to jump into,
though.

- A bunch of stuff is now defined in one header, engineapi.h
- engineapi.c is responsible for setting up any interfaces/stuff that's
used in more than one place
- mkgamedata is pretty much rewritten and now supports nested
conditionals
- gamedata variables no longer have the gamedata_ prefix because it was
just annoyingly long all the time
- vcall macros are somewhat revamped and support dynamic (gamedata)
indices
- Portal 1 FOV can be set anywhere from 75-120 using fov_desired -
tested in both the main versions currently used by runners
- A few typos were also fixed ("intput," "writeable," "indexes")

Default gamedata values actually work the way they're supposed to now.
|
|
Thanks Aciidz for helping test this.
|
|
They're literally always defined thusfar, and it's always possible to
include specific headers for other stuff. So, rather than litter the
source with defines (which might not even work in the likes of os.h if
some other system header already decided to define/include stuff), let's
just define it at the build script level.
|
|
This brings the DLL size down to a quarter of what it was. Dunno why
Clang doesn't do this by default, but apparently it doesn't!

hook_inline() uses the new x86_len() function to get instruction lengths
instead of doing full-blown disassembly, which should be a tiny bit
quicker, and also removes the next for about 90KiB of lookup tables and
such in the final binary. The code-digging logic in demorecord is also
rewritten to be opcode-based rather than mnenmonic based. In general,
going forward the plan is to always rely on opcodes and thus avoid a
bunch of disassembly work every plugin load.
udis86 is still in the tree for now to provide dbg_asmdump(), but it's
only compiled into debug builds and left out of releases completely. As
such, the whole BSD licence statement is also gone from the distribution
LICENCE files. There's now also a dbg_toghidra() which spits out a
rebased address to look stuff up for proper reverse engineering, which
might be more useful than dbg_asmdump() anyway. If nobody ends up using
the latter ever again, udis86 could get chucked completely. We'll see.
Also shoehorned into this commit are a couple more forgotten copyright
year bumps and some general minor cleanup here and there, because I
couldn't be bothered wading through all the diff hunks. Oh, and
makebindist.bat now makes an effort to make the zip file timestamps
predictable/reproducible. That should be a different commit for sure,
but oh well too bad.
|
|
They're still temporary, I promise, but this will make tweaking the
toolchain or turning debug builds on and off a lot simpler.
|
|
This also introduces some stuff for interacting with the current plugin
list. Other plugin management utilies are Coming Soon...
|
|
It's archive so you can set m_rawinput 1, load SST via VDF and then
never think about it again.
|
|
Important note: it doesn't WORK on Linux, and there's tons of warnings
and stuff, but it's easier to work on when all the compiler output and
whatnot is there.

This is done through a new "fixes" file which will probably become one
of those silly dumping grounds that every project has to have somewhere
to put random miscellaneous crap in.
These are mainly hidden in L4D2 but they just get unilaterally unhidden
if they exist, just to be sure they're accessible.
As a bonus, it turns out that unhiding a single cvar also allows us to
set sv_cheats 1 in Left 4 Dead 2, bringing an end to the need to port-
forward a listen server for co-op practice.

With code from Bill. Thanks Bill!
