Most of these tests could be modified to work with ALPS, but since
  ALPS support is going way soon, just disable the tests as appropriate.

Revert logic originally added for bug 3166.
  Revisit as time permits.
bug 3166

job_queue_rec wasn't being free'd before continues and breaks.

Add new-lines in some log messages to better reflect the actual I/O
  to apbasil.

unbuffered stdout.  After that commit 4ce0be75 was added which appeared to bandaid the
fallout making the only place using the unbuffered option was introduced in the former commit and
only really have unbuffered output on a PTY.  The latter commit would potentially send back
unfinished output without a newline causing jumbled output when expecting buffered output thus
resulting in potentially jumbled/unbuffered output.

I was able to reproduce this regularly with test1.31.

In any case making it so the code is clearer to read is a win.

Leaving RPC changes in place. Will add back into 17.11.

bug 3366

This reverts commit b9bff82f.

The dbd_list_msg_t was uninitialized in a bunch of places and the
  return_code variable in the structure was being referenced,
  resulting in valgrind error reports

No change in logic, just added values to comments in a long enum
  to more easily identify their values

First noticied by Brian.

It was leaking memory otherwise
