fa7976599c repo: refactored repository interfaces (#780)
- `repo.Repository` is now read-only and only has methods that can be supported over kopia server
- `repo.RepositoryWriter` has read-write methods that can be supported over kopia server
- `repo.DirectRepository` is read-only and contains all methods of `repo.Repository` plus some low-level methods for data inspection
- `repo.DirectRepositoryWriter` contains write methods for `repo.DirectRepository`

- `repo.Reader` removed and merged with `repo.Repository`
- `repo.Writer` became `repo.RepositoryWriter`
- `*repo.DirectRepository` struct became `repo.DirectRepository`
  interface

Getting `{Direct}RepositoryWriter` requires using `NewWriter()` or `NewDirectWriter()` on a read-only repository and multiple simultaneous writers are supported at the same time, each writing to their own indexes and pack blobs.

`repo.Open` returns `repo.Repository` (which is also `repo.RepositoryWriter`).

* content: removed implicit flush on content manager close
* repo: added tests for WriteSession() and implicit flush behavior
* invalidate manifest manager after write session

* cli: disable maintenance in 'kopia server start'
  Server will close the repository before completing.

* repo: unconditionally close RepositoryWriter in {Direct,}WriteSession
* repo: added panic in case somebody tries to create RepositoryWriter after closing repository
  - used atomic to manage SharedManager.closed

* removed stale example
* linter: fixed spurious failures

70d4c8764a cli: improvements to content selection for list/rewrite/stats/verify (#409)
They now uniformly support 3 flags:

--prefix=P       selects contents with the specified prefix
--prefixed       selects contents with ANY prefix
--non-prefixed   selects non-prefixed contents

Also changed content manager iteration API to support ranges.

cli: add --prefix to 'blob gc' and 'blob stats'

6cb9b8fa4f repo: refactored public API (#318)
* This is 99% mechanical:

Extracted repo.Repository interface that only exposes high-level object and manifest management methods, but not blob nor content management.

Renamed old *repo.Repository to *repo.DirectRepository

Reviewed codebase to only depend on repo.Repository as much as possible, but added way for low-level CLI commands to use DirectRepository.

* PR fixes

c8fcae93aa logging: refactored logging
This is mostly mechanical and changes how loggers are instantiated.

Logger is now associated with a context, passed around all methods,
(most methods had ctx, but had to add it in a few missing places).

By default Kopia does not produce any logs, but it can be overridden,
either locally for a nested context, by calling

ctx = logging.WithLogger(ctx, newLoggerFunc)

To override logs globally, call logging.SetDefaultLogger(newLoggerFunc)

This refactoring allowed removing dependency from Kopia repo
and go-logging library (the CLI still uses it, though).

It is now also possible to have all test methods emit logs using
t.Logf() so that they show up in failure reports, which should make
debugging of test failures suck less.

6f5abf5e09 added content.Manager Iterate()
This uses callbacks avoids having to buffer
all content infos in memory and does not require holding a lock.

54edb97b3a refactoring: renamed repo/block to repo/content
Also introduced strongly typed content.ID and manifest.ID (instead of string)

This aligns identifiers across all layers of repository:

blob.ID
content.ID
object.ID
manifest.ID
