/*
* Sparsemap
*
* This is an implementation for a sparse, compressed bitmap. It is resizable
* and mutable, with reasonable performance for random access modifications
* and lookups.
*
* The implementation is separated into tiers.
*
* Tier 0 (lowest): bits are stored in a sm_bitvec_t (uint64_t).
*
* Tier 1 (middle): multiple sm_bitvec_t are managed in a chunk map. The chunk
* map only stores those sm_bitvec_t that have a mixed payload of bits (i.e.
* some bits are 1, some are 0). As soon as ALL bits in a sm_bitvec_t are
* identical, this sm_bitvec_t is no longer stored, it is compressed.
*
* The chunk maps store additional flags (2 bit) for each sm_bitvec_t in an
* additional word (same size as the sm_bitvec_t itself).
*
* 00 11 22 33
* ^-- descriptor for sm_bitvec_t 1
* ^-- descriptor for sm_bitvec_t 2
* ^-- descriptor for sm_bitvec_t 3
* ^-- descriptor for sm_bitvec_t 4
*
* Those flags (*) can have one of the following values:
*
* 00 The sm_bitvec_t is all zero -> sm_bitvec_t is not stored
* 11 The sm_bitvec_t is all one -> sm_bitvec_t is not stored
* 10 The sm_bitvec_t contains a bitmap -> sm_bitvec_t is stored
* 01 The sm_bitvec_t is not used (**)
*
* The serialized size of a chunk map in memory therefore is at least
* one sm_bitvec_t for the flags, and (optionally) additional sm_bitvec_ts
* if they are required.
*
* (*) The code comments often use the Erlang format for binary
* representation, i.e. 2#10 for (binary) 01.
*
* (**) This flag is set to reduce the capacity of a chunk map.
*
* Tier 2 (highest): the Sparsemap manages multiple chunk maps. Each chunk
* has its own offset (relative to the offset of the Sparsemap). In
* addition, the Sparsemap manages the memory of the chunk maps, and
* is able to grow or shrink that memory as required.
