* cli: fixed remaining testability indirections for output and logging
* cli: added cli.RunSubcommand() which is used in testing to execute a subcommand in the same process
* tests: refactored most e2e tests to invoke kopia subcommands in-process
* Makefile: enable code coverage for cli/ and internal/
* testing: pass 'testing' tag to unit tests which uses much faster (insecure) password hashing scheme
* Makefile: push coverage from PRs again
* tests: disable buffer management to reduce memory usage on ARM
* cli: fixed misaligned atomic field on ARMHF
also temporarily fixed statup-time benign race condition when setting
default on the timeZone variable, which is the last global variable.
* testing: ensure tests are releasing all buffer pools to reduce memory usage, we had huge leaks
* object: reduced complexity and memory usage of TestEndToEndReadAndSeekWithCompression
* manifest: more test fixes
* trivial: update comment

* object: fixed race condition between Result() and Checkpoint()
This would sometimes result in indirect objects having empty object IDs.
Fixes#648
* upload: ensure checkpoints never containt empty object IDs.
* testing: reduce armhf test weight
* performance: added buf.Pool which can be used to manage ephemeral buffers for encryption and compression
* repo: switched object writer to buf.Pool
* content: switched encryption to use buf.Pool
* object: switched compression to use buf.Pool
* testing: added missing content manager Close()
