keep 'em sorted
Merge branch '5.4' into PHP-5.4

* 5.4:
  keep 'em sorted
  Fixed SNMP_ERR_TOOBIG handling for bulk walk operations
Added an opcode to opcode name map
That way extensions etc. don't have to maintain their own lists anymore.
Also as phpdbg is included and needs such a map, it'd be counterproductive to need to change two things on every new opcode.
Fixed build...
