- Get access to dart:io internal signal listening function using API instead of mirrors.
- Service isolate can start with service deactivated.
- Load Observatory front end resources only when service activated.
- Do not execute Dart Service code until service is activated.
- Register live isolates when service is activated.
- Startup refactored to allow for future use of script snapshots.

Two types of metrics:
* Counter - a measured value
* Gauge - A measured value with a min and max
Follow up CLs for the backend:
* Support for internal VM metrics (implemented in C++ but visible over the service).
Follow up CLs for the frontend:
* Query list of metrics
* Get latest value of a metric
* Collect values over time and graph them.
I'd like some feedback on the API and the data reported.

* generation for just the script file: ~12ms
* generation of dart:core (after executing fac script): ~150ms
* generation of dart:core-patch/array.dart: ~12ms

1. When the input to a BoxInteger operation is in smi-range, we can eliminate
the range check and just perform a smi-tag operation on the input.
2. There was a bug in checking for smi-overflow for range boundaries: Calling Smi::IsValid
with a int64_t argument resulted in silent truncation of the input and therefore a wrong result.
Compiling with -Wconversion would have caught this, but currently we cannot compile with this flag
because of too many broken places.
Instead, I removed Smi::IsValid64 and created one variant Smi::IsValid that is specialized for the
input type with a template parameter. This way calling Smi::IsValid is always safe and will never
result in silent alteration of the input argument.

- Redo layout of page.
- Show human readable strings for used, free, and external memory for each space.
- Track time of last forced GC/accumulator reset in isolate and display them in allocation profile page.
- Track allocation statistics on Class object itself.
- Make isolate's heap reporting use heap's PrintToJSON.
- Manually insert allocation profile table rows into dom (removes usage of template repeat).
- Add some timing information to allocation profile page update (to help diagnose slow downs).
Other changes:
- Upgrade to Polymer 0.11-dev (finally ends erroneous console spam).
- Replace enteredView/leftView with attached/detached (polymer change).
- Add <link> tag to polymer.html for each element (polymer change).
- Move <script> tag outside of element (uniformity, clarity).
- Remove unused collapsible-content element.

Add retaining_path instance command to VM service, exposed in the Observatory
with a [find] eval-link in instance view. By default shows up to 10 elements,
possibly followed by [find more] which doubles the number of elements shown.
Change RetainingPath to include the object itself.
Always include an id in Object::PrintJSONImpl, to avoid instance-ref crashing on
internal objects.

Improve the isolate view and isolate summary.
Details:
- Rig DbgMsgQueueList so it can run even when the debugger hasn't started.
- Add <action-link> element for pause/resume actions.
- Introduce new flex-percentile css classes.
- Add <isolate-run-state>, <isolate-location>, <isolate-shared-summary>, and <isolate-counter-chart> elements. Counters are now displayed as a pie chart instead of as text.
- Reorg <isolate-view> and <isolate-summary> substantially.
- Add shared style sheet to <script-view>.
- Combine pause-on-start/pause-on-exit with other debugger pause events and present a consistent representation for these in the vm service. Reorg how pause events are shown in <isolate-run-state>.
- Give the user a nicer message when an isolate is still loading.
- Move the /resume command to /debug/resume. Implement this with a bool in the Isolate class which is used to smuggle resume requests from the vm service to the dart embedding api.
- Add the /debug/pause command to the vm service
- Break the DebuggerEvent struct out into its own top-level class. Add JSON printing.
etc.

This allows us to remove the dependency on bootstrap.css (removal of bootstrap.css from third_party will happen in follow up CL).
As a side effect of this, the following changes have occurred:
- Removed Google Charts Table from allocation profile pane.
- Add a SortedTable view-model (used in allocation profile).
- Changes to CPU profile tree view.
- Consolidate string formatting utility functions.
There is some UI regression (font size is one size too small) that will have to be addressed in follow up CLs.
