fbb4879d81 Change fold_heads to do basic Journal presence check 
This at least checks the file is present, and the Key exists in the
index of that file.  If the value is corrupt it will be removed by
compation, and then this will fail (unless the file is never compacted).

TODO: resolve issus of files which are corrupt - but never compacted
- a job for backup?

4d12dfe0ab Returning snapshots 
If the clerk updates the manifest - it might not recognise changes to
the manifest made since the clerk took the manifest.  So the penciller
must merge its view of the snapshots back in to the updated manifest

fa9daf8696 Correct async fold 
fold objects which snaps in the fold was implemented incorrectly - it
took information from the LedgeCache at the point of the request, not
at the point of the fold.  So the LedgerCache SQN may have been
surpassed in the Penciller by the time the fold was called.

50d95ef6aa Move snapshot inside of the fold function 
riak_kv_sweeper gets the async fold function, then determines if the
function can be called.  If the system is busy the fold may be queued,
and may never be acted upon.

This may cause issues with snapshot timeouts etc.

e01efe02f6 Long snaphsot timeout increase 
Increase this to 90 minutes.  The first time all the snapshots are
rebuilt it may take a long time, but they all get scheduled together -
and queued until concurrency limits allow it to be completed.

currently the snapshot is made on initialisation, and only released
when completed (which may be after the queue).  so the last couple of
snapshots were over-shooting the 1 hour.

1fdcdf3b37 Midblock size - lookup 
No real reason for the midblock to be smaller in lookup slots - so give
the blocks a more consistent size

64e944d9ba Change to 5 blocks in SST Slot 
Change to 5 blocks is intended to make the blocks in lookup slots
fractionally smaller, but more importantly to introduce a middle block
that cna be opened in a binary-split style fashion to reduce the number
of blocks that need to be opened for range queries.   Worst case for
full slots is 3 blocks now not 4.

dd0316eedf Yield on query selectively 
Still not clear if yielding is the cause of memory problems, but taking
it away universally has impacted throughput.  At the very least we
should continue to yield on high-contention files (those at higher
levels), where the processes are more likely to be quickly terminated
anyway allowing GC to be invoked.

Looking into theory that use of term_to_binary is imperfect.  Also may
be better to compress values only when they are compacted?
