- Add Timeline::ReclaimAllBlocks and Timeline::ReclaimIsolateBlocks utility functions to ensure that all cached blocks are closed before reporting the timeline
- Adjust Timeline_Dart_GlobalTimelineGetTrace to exercise block reclaiming
- Add ability to reclaim blocks from threads entered into an isolate
- Fix IsolateTimelineEventFilter to actually filter out open blocks
- Make some existing tests call Timeline::ReclaimIsolateBlocks before reporting
- Added implementation and locking notes to timeline.cc

I was able to convert 49 SNPrint(NULL, 0, ...) patterns to use the
macro. I had to use a #define for the format string 5 times due to
uses that didn't fit the macro.
2 occurences of SNPrint(NULL, 0, ...) had >=2 possibilities for the
format string based on runtime values, and I didn't try to convert
them.
Fixed ~10 format strings.

- Initialize and shutdown timeline recorder with VM.
- Allocate global blocks for timeline events without an isolate.
- Stop storing the Stream pointer inside a TimelineEvent.
- Store category name in TimelineEvent.
- Store isolate pointer in TimelineEvent.
- TimelineEventRecorder::WriteTo is full VM dump.
- Allow JSONStream to be used without an isolate.
- When a ThreadRegistry is deleted, Finish all open timeline blocks.
- PrintJSON takes a filter.

- Add TimelineEventBlockIterator - iterate over TimelineEventBlocks.
- Add TimelineAnalysisThread - All events for a specific thread.
- Add TimelineAnalysis - Utility for analyzing timeline events.

- Each isolate has its own TimelineEventBuffer
- Each isolate has TimelineEventStreams for API, Compiler, Embedder, Isolate, and GC
- Compiler, Isolate, Embedder, and GC are being inserted into the stream
- Basic unit tests
- Dart API for injecting timeline events
- Arbitrary number of native and Dart arguments can be attached to each event
- JSON printing
- Output can be loaded by about://tracing
- Add --timeline-trace-dir flag
Short term follow up CLS:
- Service protocol requests to enable / disable tracing and retrieve a trace
- UI for Observatory
- Dart code EventStreams and Events
