This fixes usage of uninitialized variable in ACSStringPool::PoolEntry objects
The initial version (before 66d15dc) increased pool size by one entry and assign all its members right after that
The improved version reserved MIN_GC_SIZE entries but didn't initialize anything except the first one
ACSStringPool::FindFirstFreeEntry() cannot find the proper entry as it uses PoolEntry::Next member for list traversal
It's enough to initialize Next member with FREE_ENTRY value because other fields will be assigned anyway inside ACSStringPool::InsertString()

This addresses the main issue with TObjPtr, namely that using it required pulling in the entire class hierarchy in basic headers like r_defs which polluted nearly every single source file in the project.
It will now store the level numbers that lock a string instead of just incrementing a counter. This should make it more robust because each level can lock a string only once and some possible leftover garbage data won't be able to cause a lock decrease when a savegame is being reloaded.
This is different from the original "Death Scripts" idea. This tackles
some issues I've found with the original idea (now you can have as many
scripts as you want, not just global and actor-defined). Also takes care
of other complaints about the original idea and push request. Flags and
their use are in code comments.
The only reason this even existed was that ZDoom's original VC projects used __fastcall. The CMake generated project do not, they stick to __cdecl.
Since no performance gain can be seen by using __fastcall the best course of action is to just remove all traces of it from the source and forget that it ever existed.
Fixing this required adding an external list of active stack objects that the garbage collector can access.
A nice side effect: It's no longer necessary to pass around the stack info to various functions that might end up triggering a garbage collection.
The reason for defining them is to be able to fill out the Eternity translation table for GZDoom's Extradata parser.
Most of the new specials are mere specializations of ZDoom's Generic_* functions and occupy positions above 255 to avoid filling up the last remaining free slots available for Hexen format maps.
Allowing action specials greater than 255 required a few changes:
* all access to action specials is now through a small set of access functions.
* Two new PCodes were added to ACC to handle these new specials from scripts.
* a minor change to the network protocol, so netgame and demo version numbers were bumped.
* FS_Execute is now properly defined in p_lnspec.cpp.
Two of the newly added specials - generalizations of the special 'close Door in 30 seconds' and 'raise door in 5 minutes' sector types, will also be available to Hexen format maps. The rest are limited to use in ACS, UDMF and DECORATE.
This also adds 'change' and 'crush' parameters to most Floor_* and Ceiling_* specials, again to match Eternity's feature set.
- Fixed: When an ACS string pool was read from a savegame, FirstFreeEntry
would not be updatedt, except by the Clear() function. This left FirstFreeEntry
at 0, which meant the next string added to the pool would always go in
slot 0, whether it was free or not.
major change to ACS's workings. However, I had an epiphany yesterday and just had to do this, since it seems like too big a deal to hold off until a later release:
- Dynamically generated strings returned via strparam and get(user)cvar now last as long as they
need to. They do not disappear at the end of each tic. You can now safely store them in
variables and hold on to them indefinitely. In addition, strings from libraries no longer
require you to load the exact same libraries in the exact same order. You can even store a
library's string in a world variable and retrieve it on another map that doesn't load the
library at all, and it will still be the correct string.
- ACS library IDs now only get 12 bits instead of 16 so that each string table can hold up
to about a million strings instead of just 65536. This shouldn't be a problem, although it
means that save games that had strings with the larger IDs stored in variables are no
longer compatible. Since many saves don't involve libraries at all, and even many that do
are not actually affected, I'm not bumping the min save version. The worst that can happen
is that you get no text at all where some was expected.

* acsprofile clear - Resets all profiling statistics to 0.
* acsprofile [<sort-function>] [<limit>]:
* <sort-function> is an optional argument that specifies which column to sort on (total, min, max, avg, or runs). The default is total.
* <limit> is an optional argument that specifies how many rows to limit the output to. The default is 10. 0 or less will print every script or function that has at least one run.

and two new functions, both of which are intended for use in conjunction with SetHUDSize:
* SetHUDClipRect(x, y, width, height[, wrapwidth]) - Set the clipping rectangle for future
HUD messages. If you do not specify <wrapwidth>, the HUD message will be layed out as
normal, but pixels outside the rectangle will not be drawn. If you specify <wrapwidth>,
then the message will be wrapped to that width. Use SetHUDClipRect(0, 0, 0, 0[, 0]) to
reset everything
back to normal.
* SetHUDWrapWidth(wrapwidth) - Sets the wrapping width for future HUD messages without
altering the clipping rectangle. If you set the wrapping width to 0, messages will wrap
to the full width of the HUD, as normal.
* HUDMSG_NOWRAP - A HUDMessage() flag that disables wrapping for one message. It is
functionally equivalent to SetHUDWrapWidth(0x7FFFFFFF), except that it only affects the
message it's attached to.
