If a command is not specified to CommandStream, request a "shell"
session rather than running exec. This allows targets that do not have a
true "shell" which supports exec to instead return a raw shell session.
Conversion between packet formats can create empty additional
answers fields, which net-dns cannot handle.
Update net-dns' packet parser to be able to deal with empty arrays
such that it doesn't try to call :data on a nil, which is the only
element of an empty array.
Props to mubix for identifying this issues.
removed vendored net::ssh
pulled in net:ssh gem
made Rex::Socket::SSHFactory clas to bridge rex sockets in
Renamed getpeername to getpeername-as_array to not override

Aside from codebase-wide changes, nearly all of these tests haven't been
touched since before 2010, and there is no effort to maintain this style
of testing. We've moved on to (correctly) seperating out our tests from
our codebase.
This solves the looping problem. Since the TCP connection wouldn't
necessarily close, we couldn't count on a 0-length recv, and the
connection was timing out. Changed it so send_tcp can take a block, in
which we do parsing. AXFR responses are sandwiched between SOA answers,
so when the second one is reached, the transfer is done.
This is also cleaner for existing code that uses send_tcp, since if no
block is passed, it just returns the first response and tears down the
connection, just like it used to.
This required some changes to send_tcp: it now loops, reading as many
length-prefixed DNS responses as are available before the connection
closes. This shouldn't affect other uses of the function, since most
questions only have one response in answer.
AXFR support in net-dns is broken. This fixes it, and makes the
requisite modifications to enum_dns module. Basic problem is that AXFR
responses consist of a chain of DNS replies, not a single reply with
multiple answers. Previously, only the first of these replies, the SOA
record, was returned. Also added some exception handling to avoid
problems like #483.
