[Tarantool-patches] [PATCH luajit 0/2][v2] Fix cdata finalizer table

[Sergey Bronnikov]

From: Sergey Bronnikov <sergeyb at tarantool.org>

Branch: https://github.com/tarantool/luajit/tree/ligurio/lj-1168-heap-use-after-free-on-access-to-CTState-finalizer-nointegration
NOTE: Jobs with Tarantool regression tests has failed because
patch "FFI: Turn FFI finalizer table into a proper GC root."
broke Tarantool build and fix (see below) must be applied before
a bump to LuaJIT version with proposed patches.

Branch with fix in Tarantool: https://github.com/ligurio/tarantool/tree/ligurio/lj-1168-heap-use-after-free-on-access-to-CTState-finalizer
Issues:
- https://github.com/luaJIT/luaJIT/issues/1168
- https://github.com/tarantool/tarantool/issues/10199

Mike Pall (2):
  FFI: Treat cdata finalizer table as a GC root.
  FFI: Turn FFI finalizer table into a proper GC root.
