ec21040542 [#264] transformer: Finalize parent header once 
In previous implementation parent object header finalized twice in size
limiter + formatter. On the one hand, this added redundant action, on the
other hand, it could provoke a difference in the headers of the linking and
the last part. Change formatter to finalize parent header if it does not
container the signature. Change size limiter to reuse parent header after
last child finalization in linking child.

5470d94416 [#223] placement: Fix local and single-success placement traversal 
In previous implementation placement traverser processed incorrectly with
local placement build. Also entity incorrectly traversed the placement
vectors for fixed number read operations until success. The erroneous
behavior was due to the use of a vector number of successes instead of
a scalar number in these scenarios.

a433f9dd85 [#42] object/transformer: Fix incorrect checksums of parent object 
In previous implementations object size limiter left checksums of parent
object payload unset. This was caused by the closure that written calculated
checksums to the child object instead of parent one.

Construct payload checksum writers in separate function in order to prevent
closure bug.
