NStorm reported a failure of ARP ping scan on OpenVZ venet devices,
which don't have a MAC address and can't do ARP. We don't keep interface
flags such as NOARP at the target level, so check whether the interfaces
returned by libdnet are both INTF_TYPE_ETH and don't have
INTF_FLAG_NOARP set; otherwise call them "other" interfaces.

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").
This involves some reordering and renaming of fields from the previous
output, but hopefully more readable (less vertical whitespace). This
commit depends on the changes to stdnse.output_table to ignore assigning
new keys to nil and to use the __call metamethod to mean has_contents()
Two changes here, both minor. First, explicitly assigning a new key to
nil does not add the key to the ordered set of keys. This better
emulates the behavior of regular tables.
> o = stdnse.output_table()
> o["test"] = nil
This previously resulted in output like this:
|_ test: nil
Now it simply omits the "test:" key.
Second, I needed a way to tell whether an output table was empty or not.
Since Lua's next() function doesn't call the __pairs metamethod, it was
always returning nil. Instead, I used the __call metamethod, since it
had the least preexisting semantic meaning:
> o = stdnse.output_table()
> =o()
false
> o["test"] = 1
> =o()
true
Also fixed some spelling and documentation issues.
Script now notifies if proxy is 1. open, 2. redirecting, or 3. allowing
SOCKS clients but not matching expected patterns.
socks-open-proxy was sending requests like this:
GET http://www.google.com HTTP/1.0
Host: www.google.com
Which is appropriate for HTTP proxies, but not for SOCKS. Changed to
more appropriate "GET / HTTP/1.0" and it works.
