Lua 5.3 adds several awesome features of particular interest to nmap including bitwise operators and integers, a utf8 library, and standard binary pack/unpack functions. In addition to adding Lua 5.3, this branch changes: o Complete removal of the NSE bit library (in C), It has been replaced with a new Lua library wrapping Lua 5.3's bit-wise operators. o Complete removal of the NSE bin library (in C). It has been replaced with a new Lua library wrapping Lua 5.3's string.pack|unpack functions. o The bin.pack "B" format specifier (which has never worked correctly) is unimplemented. All scripts/libraries which use it have been updated. Most usage of this option was to allow string based bit-wise operations which are no longer necessary now that Lua 5.3 provides integers and bit-wise operators. o The base32/base64 libraries have been reimplemented using Lua 5.3's new bitwise operators. (This library was the main user of the bin.pack "B" format specifier.) o A new "bits" library has been added for common bit hacks. Currently only has a reverse function. Thanks to David Fifield, Daniel Miller, Jacek Wielemborek, and Paulino Calderon for testing this branch.
