Make stage encoding possible
...
* Fixes a bug in shikata where input greater than 0xffff length would
still use 16-bit counter
* Short circuits finding bad xor keys if there are no bad characters to
avoid
* Fixes huge performance issue with large inputs to xor-based encoders
due to the use of String#+ instead of String#<< in a loop. It now
takes ~3 seconds on modern hardware to encode a 750kB buffer with
shikata where it used to take more than 10 minutes. The decoding side
takes a similar amount of time and will increase the wait between
sending the second stage and opening a usable session by several
seconds.
I believe this addresses the intent of pull request 905

First round of bugfixes for encoders. Alphanumeric encoders no longer default the BufferRegister option, since this can lead to non-compatible exploits falling through to these encoders, selecting them, and then crashing. The new method uses a dynamic (not quite poly) geteip generator, that while not yet alphanumeric compatible, it handles most of the known use cases. Remaining items:
...
1) Figure out how to handle unicode geteip (unicode encoded, alphanum probably)
2) Add keys to the unicode payloads to force a corresponding keyu on the exploit side to enable
