BUG/MEDIUM: debug/lua: Use internal hlua function to dump the lua traceback
The commit reverts following commits:
* 83926a04 BUG/MEDIUM: debug/lua: Don't dump the lua stack if not dumpable
* a61789a1 MEDIUM: lua: Use a per-thread counter to track some non-reentrant parts of lua
Instead of relying on a Lua function to print the lua traceback into the
debugger, we are now using our own internal function (hlua_traceback()).
This one does not allocate memory and use a chunk instead. This avoids any
issue with a possible deadlock in the memory allocator because the thread
processing was interrupted during a memory allocation.
This patch relies on the commit "BUG/MEDIUM: debug/lua: Use internal hlua
function to dump the lua traceback". Both must be backported wherever the
patches above are backported, thus as far as 2.0
