Migrate away from things deprecated in Go 1.20

2023-02-15T17:30:32+00:00

"math/rand".Seed
  - Migrate to using local RNG instances.

"archive/tar".TypeRegA
  - The deprecated constant tar.TypeRegA is the same value as
    tar.TypeReg and so is not needed at all.

libnetwork/bit{seq,map}: delete CheckConsistency()

2023-01-27T16:47:43+00:00

That method was only referenced by ipam.Allocator, but as it no longer
stores any state persistently there is no possibility for it to load an
inconsistent bit-sequence from Docker 1.9.x.

libnetwork/bitmap: optimize binary serialization

2023-01-20T18:57:44+00:00

The byte-slice temporary is fully overwritten on each loop iteration so
it can be safely reused to reduce GC pressure.

libnetwork/bitmap: remove datastore concerns

2023-01-20T18:42:40+00:00

There is a solid bit-vector datatype hidden inside bitseq.Handle, but
it's obscured by all the intrusive datastore and KVObject nonsense.
It can be used without a datastore, but the datastore baggage limits its
utility inside and outside libnetwork. Extract the datatype goodness
into its own package which depends only on the standard library so it
can be used in more situations.

libnetwork/bitmap: dup from package bitseq

2023-01-20T18:33:22+00:00

...in preparation for separating the bit-sequence datatype from the
datastore persistence (KVObject) concerns. The new package's contents
are identical to those of package libnetwork/bitseq to assist in
reviewing the changes made on each side of the split.
