User buffer fixes

When a bad block is located in the first 8kB of the pool,
pmempool-info may fail, so change the bad block offset to 8kB
coded as number 16 (in 512b sectors).

Length of a bad block has to be a multiple of 8 (in 512b sectors),
because it is rounded up to a block size of the device.

Set the maximum supported block size to 4096 bytes (= 8 x 512b).

Features cannot be read before fixing bad blocks,
because reading can fail because of bad blocks.
If bad blocks are being fixed, features have to be read
after having bad blocks fixed.

... becasue they fail because of bad blocks.

.. so that only bad blocks from the given namespace were checked.

.. so that only bad blocks from the given namespace were printed out.

These are supposed to carry settings rather than copyrightable code --
and, they're filled in downstream.
