Reduce memory allocations in PMMR (#3328)
We have a pattern in the code - return Vec, turn it into an iterator, filter and collect to another Vec. The idea was to return iterator where possible to avoid allocating intermediate vecs.

Always return a typed structure from lmdb store (#3312)
We have a method get which returns a Vec, it's used in cases when we can't implement FromLmdbBytes or Readable on a desired type, eg when both traits and type are external for the current crate. This approach requires an extra allocation of a Vec, this PR introduces a method which accepts desirialzer as closure, which allows to desrialize in place without an intermidiate heap allocation.

It's still possible to get a Vec if needed, just pass a Vec constructor to get_with.

Reduce number of allocations in to_key calls (#3311)
We have to make an extra allocation per db get request because key generation function to_key takes Vec. Taking byte slice (AsRef<[u8]> to be precise) also simplifes the code a bit.

Optimize Option to Error conversion (#3036)
To convert option to error we generate an error message. In some places
it contains header or block hash code or other data which is costly to
produce. So during the initial header sync we spend 12% of all time on
generating those messages (in 99% cases we don't use it). This PR
introduces a lazy generation of error messages which completely
eliminates CPU load during the header sync.
