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.
This reverts commit 317eb0de31f40454cd213296e6cee71c1f78e006.
This commit started as a way to fix perceived problems but eventually I found
the script worked correctly (I had a misunderstanding of the purpose). I kept
the small changes but ended up breaking the script anyway. So let's just revert
this.

NSE: make minor adjustments to script
NSE: add new script http-internal-ip-disclosure

Previously, if a host had not domain set, the script would crash when
trying to get the domain portion of the reverse-DNS name. Now, it adds
the blank string and tries to resolve the bare hostname "wpad".
Lua operator 'not' has higher precedence than '==', so the statement
not x == "something"
is equivalent to:
(not x) == "something"
which will always be false, since the value of 'not x' will be either
'true' or 'false' and the string "something" is not the boolean 'true'
or 'false'. This is usually resolved by using the '~=' operator.
Sometimes (e.g. when using an external API), a script wants to connect
by name to a server and doesn't care whether IPv4 or IPv6 is used. By
passing the "any_af" option, the first resolved address of any address
family will be used, allowing external-category scripts which used to
fail with -6 to succeed.
The rpcinfo script can now set version info just like rpc-grind. Since
this requires considerably less traffic than rpc-grind, I made rpc-grind
depend on rpcinfo so that it will avoid running if we can get the
version information this way instead.
Also changed rpcinfo to only run on port 111, not on "rpcbind" service
since that's what -sV labels any detected RPC service.
