Francois Perrad 66ab676616 Add new upstream Lua patches and rename all patches for consistency
Several new upstream patches against the latest version of Lua have
appeared on http://www.lua.org/bugs.html. This commit adds them to
Buildroot, and also renames the other patches to have a coherent patch
naming: lua-bugX, where X is the identifier of the bug as visible on
http://www.lua.org/bugs.html. Note that bug 1 and 2 are not associated
with patches, which explains why the first patch is labeled lua-bug3.

Fixes bug #2365.
