Add more logging
Remove API/library logic: The API does not exist today and the
  command line interfaces are in flux, so just clean up the code
  while we debug.
Updates for new Cray interfaces (there have been major changes
  in past couple of months).

Cray tools advertised to output in JSON format are really using
  Python. Added a function to convert Python to JSON so we can
  use JSON-C library for parsing.

The commands and their arguments have changed substantially in
  recent months. Code is untested.

Other tests are still failing, but I don't have time to investigate now.

Updates of existing bluegene advanced reservations did not work at all.
Some multi-core configurations resulting in an abort due to creating
  core_bitmaps for the reservation that only had one bit per node rather
  than one bit per core.
These bugs were introduced in commit 5f258072

Layouts packed representation adds trailing '\n' to each string.
Ensure that layout names, when packed for an info RPC also bring
their own '\n', thus avoiding to add when printing the result.

the introduction of the record count in the buffer returned while packing
layouts introduced a regression in the state saving logic. The state dump
logic was based on an iteration over the packed strings, stopping at the
first invalid string found, thus nothing was dumped because. This commit
start by extracting the record count before iterating on the packed
strings.

Logic was assuming the reservation had a node bitmap which was
  being used to check for overlapping jobs. If there is no node
  bitmap (e.g. a licenses only reservation), an abort would result.
