+Subject: add Lua 5.4 support
+
+Probe lua54/lua5.4/lua-5.4 in meson.build/meson.options, relax the
+runtime version check in player/lua.c to accept 5.3 and 5.4, and keep
+Lua 5.1/5.2's permissive luaL_checkinteger behavior (truncate
+non-integral floats instead of raising "number has no integer
+representation") so scripts like osc.lua keep working on 5.4.
