4615cda03f Important fragments bug fix... 
start, finish that had been adjusted wasn't getting reflected in final
returned deparsed.offsets dictionary. Redo keeping API compatibility,
i.e we still use namedtuple NodeInfo.

6fb879d0d8 Detect some erroneous decompilations 
Until we can actually prevent these in grammar rules, we will warn of
improper decompilations.

Also, we now stop when we hit a decompile error. Previously we were not.

2328ca7a55 Break out make_function() into its own file. 
It is already too complex and will get worse in Python 3.6.

Note: make_function in fragments.py is still inside and
probably needs fixup.

c7788e4545 disassemble -> ingest where appropriate 
As part of tokenization for (de)parsing, we need to do something like a
disassembly, but is is really a little different.

Disassembly, strictly speaking, is done by the xdis module now.
What "ingestion" does is massage the instruction tokens to a form that is
more amenable for parsing.

In sum, ingestion is different than disassembly, although disassembly is
generally the first part of ingestion.

fa7d8f955a WIP Python-2.6 but don't remove opcodes 
The scheme for turning 2.6 bytecode into 2.7 psuedo bytecode
I think is a lose.

I won't work for fragment handling.

Instead, change the grammar and syntax rules

This also has the benefits:

* We see how code generation changed over releases
  by looking at grammar and semantic rules rather
  than arbitrary code
* We can better assocate with what's running
  (in a sense this is a restatement of broken fragment
   handling)
* With the right structure in place we are in a better position to
  handle 2.5, 2.4, etc. That is, after a while, the incremental changes
  to get say from python 2.3 bytecode to python 2.7 are great.
