Split collect, concurrent, vfs, windows into package-level BUILD files.
Move clock classes out of "util", into their own Java package.
Move CompactHashSet into its own Java package to break a dependency cycle.
Give nestedset and inmemoryfs their own package-level BUILD files.

Don't pass the Command annotation explicitly, but add it to CommandEnvironment
instead; most modules don't need it in the first place, so it was a lot of
boilerplate for not much. Also change it so that the command is passed to the
constructor.
Add some documentation to the beforeCommand method.

keep references to actions indefinitely. Instead, once an action is finished executing, keep just some metadata about it. This allows actions to be unconditionally dropped when running with --batch, --discard_analysis_cache, and --keep_going, even if profiling is enabled.
The additional fields here add between 8 and 12 bytes per component, and we have one component per action. This additional penalty is only incurred when we are already saving memory, so I think it's ok. The full penalty will be realized only towards the end of the build, when every action has started executing at least once. Users can still specify --noexperimental_enable_critical_path_profiling if they want to squeeze even more memory out.

information is useful, the critical path computer retains references to objects that could otherwise be cleared to save memory.
This change is probably not worth submitting on its own -- the benefit it provides is too slight. But my follow-up change unknown commit needs this option to be effective -- the critical path currently hangs on to references to every action in the graph, so we can't drop references to actions if it's enabled.
The critical path could probably be reworked in the future to not hang onto those references.

The start time of critical path component wasn't recorded correctly since #getStartWallTimeMillis() didn't work right. However, since profiler tasks store nanotime anyway, it's pointless to try to convert back and forth.

The headers were modified with
`find . -type f -exec 'sed' '-Ei' 's|Copyright 201([45]) Google|Copyright 201\1 The Bazel Authors|' '{}' ';'`
And manual edit for not Google owned copyright. Because of the nature of ijar, I did not modified the header of file owned by Alan Donovan.
The list of authors were extracted from the git log. It is missing older Google contributors that can be added on-demand.

The very long term plan is to make BlazeRuntime immutable, so that we can
run multiple commands in the same server.

instead of nanoTime. As nanoTime should only be used to compute time differences. To avoid having to pass two long values representing time (And calling twice to Clock.xxx methods per action executed) we compute the wall time by passing a clock and computing the difference from the start nano time.
