Compile Lua as C++. When Lua is compiled as C, it uses setjmp/longjmp
for error handling, resulting in failure to unwind intermediate stack
frames. Trying to ensure no objects with non-trivial destructors are in
scope when raising a Lua error is error-prone. In particular,
converting an exception to a Lua error becomes convoluted, and raising a
Lua error from a constructor is effectively impossible.
Updated Lua to 5.4.4 - this includes a brand-new garbage collector
implementation with better performance. The main thing removed is the
deprecated bitlib.
Updated sol2 to version 3.3.0 - this adds support for Lua 5.4 and fixes
a number of issues, including not correctly handling errors when Lua is
built as C++.
Updated LuaFileSystem to version 1.8.0 - this adds support for symbolic
links on Windows, as well as Lua 5.4 compatibility.
Updated LuaSQLite3 to version 0.9.5 - this fixes issues in
multi-threaded environments, as well as Lua 5.4 compatibility.
Fixed double-free after attempting to construct a debugger expression
from Lua with an invalid string, and exposed expression error to Lua in
a better way.
Added warning level print function to Lua.
Fixed saving cheats with shift operators in expressions, although this
code isn't actually used as there's no cheat editor.
This effectively reverts b380514764 and
c24473ddff, restoring the state at
598cd52272.
Before pushing, please check that what you're about to push is sane.
Check your local commit log and ensure there isn't anything out-of-place
before pushing to mainline. When things like this happen, it wastes
everyone's time. I really don't need this in a week when real work™ is
busting my balls and I'm behind where I want to be with preparing for
MAME release.
