The functionality was moved to script_lua.c under callFunction function. Its purpose is to call the Lua function already located on the top of the Lua stack. Used the new function on eval.c to invoke Lua code. The function will also be used to invoke Lua code on the Lua engine.

Script unit is a new unit located on script.c. Its purpose is to provides an API for functions (and eval) to interact with Redis. Interaction includes mostly executing commands, but also functionalities like calling Redis back on long scripts or check if the script was killed. The interaction is done using a scriptRunCtx object that need to be created by the user and initialized using scriptPrepareForRun. Detailed list of functionalities expose by the unit: 1. Calling commands (including all the validation checks such as acl, cluster, read only run, ...) 2. Set Resp 3. Set Replication method (AOF/REPLICATION/NONE) 4. Call Redis back to on long running scripts to allow Redis reply to clients and perform script kill The commit introduce the new unit and uses it on eval commands to interact with Redis.

The following variable was renamed: 1. lua_caller -> script_caller 2. lua_time_limit -> script_time_limit 3. lua_timedout -> script_timedout 4. lua_oom -> script_oom 5. lua_disable_deny_script -> script_disable_deny_script 6. in_eval -> in_script The following variables was moved to lctx under eval.c 1. lua 2. lua_client 3. lua_cur_script 4. lua_scripts 5. lua_scripts_mem 6. lua_replicate_commands 7. lua_write_dirty 8. lua_random_dirty 9. lua_multi_emitted 10. lua_repl 11. lua_kill 12. lua_time_start 13. lua_time_snapshot This commit is in a low risk of introducing any issues and it is just moving varibales around and not changing any logic.

This commit is only move code around without changing it. The reason behind this is to make review process easier by allowing the reviewer to simply ignore all code movements. changes: 1. rename scripting.c to eval.c 2. introduce and new file, script_lua.c, and move parts of Lua functionality to this new file. script_lua.c will eventually contains the shared code between legacy lua and lua engine. This commit does not compiled on purpose. Its only purpose is to move code and rename files.
