Consider converting bussiness logic from C to C++

As time goes I begin to see issues that aren't easily solvable in C. They can be roughly divided into 2 categories:

1. Technical
   1. Porting to Windows - this is big one, right now it's impossible to create DLL, without trying to jump over your head.
   2. Testing - Right now in order to test nexoid-ed it's needed to defined interface symbols for a test. Basically that means that in a single executable can be only single implementation of APIs (SCAPI, HAPI etc), which defies the point of testing, because normally we want to test different scenarios, like failure in a particular API call, etc. There is still a possibility to connect API to some scripting language and work with that, but for now experiments with libctl failed (#2).
2. Non-technical
   1. Readability
      1. Operator overloading - It can simplify look of executable diagrams, which was the main point of them in the first place. ttd.transactionAmount > 1 is way more readable for non-programmer than amount_compare(ttd.transactionAmount, create_bcd(1)) > 1 or something similar.
      2. Implicit memory handling - It was solved partially using ptmalloc3 and memory pools, but still one have to use special macros acpval and acpptr to allocate a copy of a variable. This can be simplified with custom allocators in C++

There is also a different proposition rewrite nexoid in Ada ...
