  cfg language: Fix binary string comparisons

When dealing with binary strings (e.g. the ones produced by {ip.pton}),
some of the string comparison operators were broken, such as: !=, >=, >,
<= and <.

  Transformations: Fix a series of buffer overrun bugs

This patch adds several buffers, on two layers, such that the following
operations are no longer broken (i.e. leading to buffer overruns and
incorrect results):

    * putting together any kind of transformation chain without the risk
      of reading and writing into the same transformation buffer

    * passing multiple transformation-enabled variables with arbitrary
      chaining lengths to a script function without the risk of any two
      of them making use of the same buffer

Many thanks to Răzvan Crainea for some timely tips!

Fixes #1572
