Add shellcode for RC4 bind and reverse stagers
...
Those stagers will encrypt the initial stage with a 128-bit RC4 key and
the stage length with a XOR key. Both keys are embedded in the stager.
This should provide good evasion capabilities in addition to some
protection against MITM reversing (if the stager is sent a different
route, like in an executable on an USB key).
Note that, from a cryptanalyst's standpoint, it is a bad idea to reuse the
same stager (or stagers with the same RC4 and XOR keys) more than once
since an identical key will result in an identical keystream and make
correlation attacks easy. But I doubt that matters in practice.
Also note that since communication after the initial statging is not
encrypted, these stagers should be used in combination with additional
encryption support in the payloads (like Meterpreter).

Merge in a rewritten windows x86 reverse_ipv6_tcp stager (The previous one seems hosed since r6744 due to new host/port offsets[1] but the shellcode blob remained the same after modification[2]) - This new one uses the block_api_call technique, is 37 bytes smaller and can handle arbitrary size stages.

Forgot the updated build.py, also add in a link to a blog post I wrote for this shellcode.

For now just adding in the new APC migrate stubs and the wow64->x64 exec stub. (fix up the build scripts and use a dedicated migrate directory for this stuff).

This patch implements a much more flexible executable creation scheme at the cost of exe size. This also adds the "-x" option to msfencode, allowing the user to specify their own executable template for generation.
