lua-lanes: update to 3.16.0

Changes:
- fix require() wrapper to return all values returned by original require()
- Lanes no longer relies on malloc/free for internal allocations, but uses the \ 
primary alloc function from the master Lua state (excepted for LuaJIT flavors, \ 
because the allocator seems to assume that it won't be used oustide the Lua \ 
state).
- __lanesclone is now called only once with 3 parameters dest, source, size \ 
-> BREAKS CUSTOM DEEP USERDATA API

parallel: Add lua-lanes

Lua Lanes is a Lua extension library providing the possibility to run multiple
Lua states in parallel. It is intended to be used for optimizing performance
on multicore CPUs and to study ways to make Lua programs naturally parallel
to begin with.
