So far, this is mostly a direct port from the block processor. The
actual fragment checksumming is not done through the thread pool.

Break convoluted, long functions up into smaller ones where the control
flow (especially locking and signalling) is more easily readable and
remove some copy and paste clean up code.

This commit makes sure the block processor enqueue function dequeues
at most a single block which it dispatches.

If an error happpens, immediately stop everything and report only the
first error that happened.
This also fixes a memory leak in the error paths of the serial and
pthread based block processors.

First, remove the "Don't checksum" flag, fragment blocks also need to
be checksumed and are also subject to deduplication. For sentinel
blocks, instead check if the size is zero.
Second, cleanly seperate the user settable flags from the non-user
settable flags and reject any block that has non-user settable or
unknown flags set.

Instead of calling a callback, the block processor now takes care of
writing the data blocks to the file in the correct order, keeping
track of fragment blocks and deduplicating blocks.
Some cleanup work remains to be done and the statistics have to be
repaired (yet again).
