Opcode names moved to a new header file
...
The array with the names of the opcodes was moved to a header file
('lopnames.h'), as it is not used by the Lua kernel. Files that need
that array ('luac.c' and 'ltests.c') include the header file to get
a private (static) copy.

change in 'LUAI_DDEC' to allow variables to be static in 'onelua'
