Building a string with var = var .. "something" has miserable time
complexities. This commit cleans up a lot of that in scripts, focusing
on packing of data with bin.pack and concatenations within loops.
Additionally, a few instances were replaced with string.rep
These scripts got removed from default:
dhcp-discover
dns-zone-transfer
These scripts got removed from intrusive:
dns-recursion
ftp-bounce
http-open-proxy
socks-open-proxy
Thanks to Toni for noticing these.

o Added a convenience top-level BSD makefile redirecting BSD make
to GNU make on BSD systems. This should help prevent bogus
error reports when users run "make" instead of "gmake" on BSD
systems. [Daniel Roethlisberger]

[NSE] The NSE Nsock Library binding no longer relies on garbage collection to
monitor the use of socket "slots". A thread (script) attempting to connect must
first obtain one of a limited number of available socket locks (usually 10 or
--max-parallelism). The binding would use garbage collection of sockets to
determine when a thread has finished using its allocated sockets. This is
unfortunately slow and requires us to constantly run the garbage collector to
cause timely reallocation. I have changed the binding to now regularly inspect
allocated sockets in the nsock_loop function. Available sockets slots are now
immediately reallocated and done with far less execution time.
See [1] for benchmarks and further explanation.

[NSE] Fixed a rare (and usually undetectable) bug that can cause a SEGFAULT.
The NSE nsock library binding may attempt to push values on the stack of
a thread that ended due to an error. It is possible that the internal
Lua stack was completely full and any further pushed values would result
in a segmentation memory violation.
This bug is very hard to reproduce with a SEGFAULT but is usually visible
when Lua assertion checks are turned on. A socket handler routine must be
called AFTER a thread has ended in error.

Fixed some global scoped variables to be local. This caused a many scripts to
overwrite each others' sockets, options, etc.

Fixed buffering problem exposed by david on nmap-dev list.
The problem was solved using a buffer to receive the data, making the script work fine in cases where the ssh packets are fragmented.
A very similar solution was applied to ssh1.lua.

[NSE] We now propogate a NSE initiated yield on a script through all user
coroutines so that NSE may resume control. Previously, scripts that would yield
in a child coroutine (e.g. a script's child coroutine generated by Lua's
coroutine.create function) would give control back to the script. A script
would yield in this way by making a blocking socket operation. NSE would be
unable to correctly resume child coroutine when the socket operation is
finished processing.
By yielding the chain of coroutines a script has operating, we allow to NSE to
handle the socket operation properly. NSE would then resume the entire chain so
execution may correctly resume at the coroutine which initiated the socket
operation. This restores the "illusion" that a script executes without
interruption.
See [1] for more information, further explanation, and some use cases.

The configure script now allows cross-compiling by assuming that
libpcap is recent enough. Previously it would quit because a test
program could not be run. libpcap will always be recent enough when
the included copy is used. The patch was contributed by Mike
Frysinger.
- openproxy.url: Url to make requests to the proxy
- openproxy.pattern: Pattern that should be checked inside the responses for requests HEAD and GET
pattern will never be used for CONNECT requests, that will only check for the connection code
Script now uses default pattern checks for default url
(checks for ^server: gws in www.google.com requests)
If openproxy.url is used, script performs code check, looking for codes 200,301,302.
If openproxy.url is used and openproxy.pattern also, script performs pattern check
- Attempts requests using HEAD and CONNECT also (not only GET, as before).
- Script now accepts destination url for doing the test as argument
- Chekings now are made using response code (200, 301, 302) and no longer google server header
