This adds read- & write-retry handling of potentially temporary errors,
as well as errors due to device disconnection.

Changelog-Entry: Fix handling of temporary read/write errors
As we've actually been displaying the read-speed in various
forms during the flashing process, this is a venture into
displaying the actual write-speed from the end of the pipeline.

Changelog-Entry: Display actual write speed
Due to the Blockmap.FilterStream not emitting a "checksum"
event (as it individually verifies specified ranges), the
flashing process would get stuck on finish.
This emits a "checksum" event on "finish" when blockmapping,
averting this issue.
Change-Type: patch
The checksum-stream being situated in front of the block-stream, which
ensures block size alignment to multiples of 512, and pads the last block,
caused the checksum to be incorrectly calculated for images where the last
block needed to be padded.
Change-Type: patch
If the speed is zero, the eta becomes Infinity, which isn't transmitted
properly over IPC for at this time unknown reasons.
To prevent the "Missing state eta" error from popping up when the speed is
zero, we set the eta to zero as well in those cases.
Change-Type: Patch
This implements a new way of image write streaming under use of pipage and blockmap, which paves the way for a few things like using network locations as sources, and imaging of storage devices (aka backups). As it allows for mutation of the streaming pipeline while it's writing, it also facilitates the development of dynamic block-mapping.
