* 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.
