2758d76b77 copy: replace --repo2 with --from-repo
`init` and `copy` use `--repo2` with two different meaning which has
proven to be confusing for users. `--from-repo` now consistently marks a
source repository from which data is read. `--repo` is now always the
target/destination repository.

89d3ce852b repository: extract Load/StoreJSONUnpacked
A Load/Store method for each data type is much clearer. As a result the
repository no longer needs a method to load / store json.

3d29083e60 copy/find/ls/recover/stats: Memorize snapshot listing before index
These commands filter the snapshots according to some criteria which
essentially requires loading the index before filtering the snapshots.
Thus create a copy of the snapshots list beforehand and use it later on.

537b4c310a copy: Implement by reusing repack
The repack operation copies all selected blobs from a set of pack files
into new pack files. For prune the source and destination repositories
are identical. To implement copy, just use a different source and
destination repository.

Parallelize blob upload/download for restic copy
Currently restic copy will copy each blob from every snapshot serially,
which has performance implications on high-latency backends such as b2.

This commit introduces 8x parallelism for blob downloads/uploads which
can improve restic copy operations up to 8x for repositories with many
small blobs on b2.

This commit also addresses the TODO comment in the copyTree function.

A more thorough improvement of the restic copy performance can be found
in PR #3513

2fc7abac35 copy: copy raw bytes of tree blobs
This avoids problems when for some reason the JSON encoding changes.
This also ensures forward compatibility with future restic versions
which might e.g. add new fields to the tree metadata.

258ce0c1e5 parallel: report progress for StreamTrees
This assigns an id to each tree root and then keeps track of how many
tree loads (i.e. trees referenced for the first time) are pending per
tree root. Once a tree root and its subtrees were fully processed there
are no more pending tree loads and the tree root is reported as
processed.

f003410402 init: Add --copy-chunker-params option
This allows creating multiple repositories with identical chunker
parameters which is required for working deduplication when copying
snapshots between different repositories.

ec9a53b7e8 copy: Mark and skip previously copied snapshots
Use the `Original` field of the copied snapshot to store a persistent
snapshot ID. This can either be the ID of the source snapshot if
`Original` was not yet set or the previous value stored in the
`Original` field. In order to still copy snapshots modified using the
tags command the source snapshot is compared to all snapshots in the
destination repository which have the same persistent ID. Snapshots are
only considered equal if all fields except `Original` and `Parent`
match. That way modified snapshots are still copied while avoiding
duplicate copies at the same time.

b0a8c4ad6c copy: Only process each tree once
This speeds up copying multiple overlapping snapshots from one
repository to another, as we only have to copy the changed parts of
later snapshots.

7048cc3e58 Add copy functionality
Add a copy command to copy snapshots between repositories. It allows the user
to specify a destination repository, password, password-file, password-command
or key-hint to supply the necessary details to open the destination repository.

You need to supply a list of snapshots to copy, snapshots which already exist
in the destination repository will be skipped.

Note, when using the network this becomes rather slow, as it needs to read the
blocks, decrypt them using the source key, then encrypt them again using the
destination key before finally writing them out to the destination repository.
