Kept Lua fallback probing logic, but now it applies to both with-lua=auto and the default with-lua=luajit: Meson tries luajit, then lua-5.4, lua5.4, lua-5.3, lua5.3, and lua; if none are present it warns and disables the Lua plugin instead of hard-failing configure.
Updated the Lua plugin dependency selection so plugins/lua/meson.build consumes the pre-resolved fallback dependency for both auto and luajit paths, while keeping explicit custom pkg-config names unchanged.
Quick rundown of benefits:
- Much faster:
- Autotools (with autogen): 22 seconds
- Meson: 7 seconds
- Meson (with ccache): 2 seconds
- Simpler:
- ~1000 lines smaller
- Single simple language
- Potentially better Windows (Visual Studio) support
What is not done:
- Complete Windows support
- OSX support (easy)
