Currently, in all input parsing procedures rely on Block's constructor to either fully construct the block or throw an exception when either there is not enough data in the supplied buffer or (in some constructor versions) if there are more data than necessary.

This task is to create exception-safe method to perform checks before creating actual block. An exception-free version of the Block's constructor can then be used to create actual block, directly supplying its type and length (no additional checks should be performed).
