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.
Libpcap only needs libnl for monitor-mode sniffing. Disabling it lets us
not worry about which -lnl or -lnl-3 linker argument to include in our
own LIBS, so Nmap builds properly no matter whether libnl is present or
not.
This was a hassle to support on AIX (several broken implmentations) and
the move to a more portable solution (using autoconfig macros) was also
troublesome. Upon review, nse_fs.cc only uses directory and link
functions, so large files support shouldn't matter. Stripping it out.
nse_fs.cc was forcing large files support, and it was broken on AIX due
to this GCC bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=20366
Now we let autoconf handle setting the appropriate defines, and also
check for this particular bug before defining.
$ svn merge -r r33518:r33513 .
and removed added scripts to the script.db.
The branch needs further refinement/testing for Windows and Mac before merging
into the trunk. There is also the latent EOF bug which is giving performance
issues.
Further work on the branch will continue in Devin's latest branch:

Currently, this just uses Python's unittest module to autodiscover
tests, which may skip some, but is better than nothing. TODO: move tests
to their own module and let the zenmap_check target test them directly.
When configuring --without-ncat, "make check" was trying to run Ncat's
test suite. This commit splits the check target into ncat_check and
nsock_check, and makes each conditional on that subsystem's configure
status.
These appear not to have any effect any more. They were initially used
to conditionally compile and link some files with replacements for
standard library functions, but seem not to have been used after r828
("Moved to nbase system for compatability funcs").
John Spencer reported that musl libc doesn't automatically include
<stdlib.h>, as Glibc does, so the configure check was wrongly failing.

Solaris 11 uses BPF packet capture rather than DLPI, which requires
different handling in many cases. The new preprocessor symbol tells when
this is the case; it is additional granularity on top of SOLARIS.
