* Rework `needle_map.CompactMap()` to maximize memory efficiency.
* Use a memory-efficient structure for `CompactMap` needle value entries.
This slightly complicates the code, but makes a **massive** difference
in memory efficiency - preliminary results show a ~30% reduction in
heap usage, with no measurable performance impact otherwise.
* Clean up type for `CompactMap` chunk IDs.
* Add a small comment description for `CompactMap()`.
* Add the old version of `CompactMap()` for comparison purposes.
Per-entry memory usage is based on `TotalAllocs`, which is incorrect - that
value is a cummulative of heap usage, which doesn't decrease when objects
are freeed.
`Allocs` is instead an accurate represeentation of actual memory usage
at the time metrics are reported.
NeedleHeaderSize happen to have the same size as NeedleMapEntrySize, except when running the 5 bytes offset variant of Seaweedfs, because it does not contain OffsetSize. This causes ECX corruption on deletes, due to the drifting offset computation (offset is always computed on a basis of 16 bytes per record instead of 17 bytes)

* Rename `command_ec_encode_test.go` to `command_ec_common_test.go`.
All tests defined in this file are now for `command_ec_common.go`.
* Minor code cleanups.
- Fix broken `ec.balance` test.
- Rework integer ceiling division to not use floats, which can introduce precision errors.
* Introduce logic to resolve volume replica placement within EC rebalancing.
This will be used to make rebalancing logic topology-aware.
* Give shell.EcNode.dc a dedicated DataCenterId type.
* fix: parse filename in PUT + refactor
* fix: master iu public url with http
* fix: better parsing and handle disposition header
* fix: take mime type from file extension if not set
fix WriteNeedleBlob to avoid duplicate write a same needle
