Decided to split up my previous pull request (#1247) to multiple PRs due to it having set of changes too broad in my opinion. Ran tests as usual for fb3 server and embedded. Updated to current master branch state. Also decided to throw in reworked ring-buffer Queue's to be more large object friendly.

TLDR: Ellimination of most of the repeated allocations for intermediate conversions, also added inplace copy methods for I/O and reworked intermediate network buffers to use proper ring-buffer resizable arrays with unitary copying instead of per-byte queueing, massively boosting large objects throughput.

Boost for large object I/O is significant. Benchmarks were performed without compression and encryption (typical for walled LAN / server sharing db with apps in single env). For small data types and writing operations, changes in practice are much smaller, but some difference in allocations can be observed still. Such an effect on performance is mostly due to ellimination of copies and ability for system to use packed operations (r/w with 64 bit ops instead of 8x8 bit ops) or even simd when dealing with the buffers, and also jit should be much happier with the new installment. For large blobs with the same mode boost can be even bigger with the bypass mode (less copies).
