- Log the parameters to RPCs
- Display messages like stack frames
- handler function and script visible
- message preview instead of local variables
- Expanded and previewed messages do not collapse when stepping within the existing message
- Mark patch classes as finalized to avoid ASSERT on class_finalizer.cc:2358 **
- Support iterating over message queues

Before a response looked like this...
{ result:<string> id:* }
...where result was always a json encoded string. This meant that
users of the service protocol had to json decode both the outer
message and the result, which was silly.
Now a response looks like this:
{ result:<map> id:* }
This means that users of the service protocol only need to decode once.
We have changed event formats as well. Previously, an event looked like this:
{ result:<string> }
(Essentially a result without an id.) The result was json encoded,
requiring the user to double-decode.
Now an event looks like this:
{ event:<map> }
This allows us to distinguish events from rpc results and avoids
double-decoding. It also avoids having an id-less rpc result mistaken
for an event.
------------
Some details and associated changes:
- Unify GCEvent and ServiceEvent in the VM.
- Move sequence number handling out of dart code and into JSONStream
in the VM. Plumbing. I needed to do this to avoid double-encoding.
Some of the dart code gets a bit simpler.
- Update C++ tests to have a sequence number.
- Change format of method/params used in Error responses to be more json-y.
- Strip out double decoding in the service lib.
- Improvements to tests. I was running into some races and other issues.
- Fail fast when we run into a message decoding problem. Instead of
returning a service exception, we now disconnect from the vm.
- VMDisconnected => ConnectionClosed.
- Add some support for a reason string when disconnecting from the vm
in the service library.

- Add the "isolate" command which allows the user to switch isolate by name or number. Supports completion.
- Add the "isolate name" command which allows the user to rename an isolate. Add the "setName" method to the service protocol to support this. Isolates now have a debugger_name() in the vm.
- The new IsolateUpdate event notifies the client when an isolate name changes.
- When an isolate is updated, update the page's isolate too, so the navbar is accurate.
- Update isolate summary to display isolate number.
- Rework how the isolate's name is computed because we were getting garbagey names in the IsolateStart event (SpawnState was not yet set).
- Make sure that the debugger doesn't subscribe to events multiple times.
- "info isolates" is now "isolate list".
- Rework reporting of vm and isolate startTime in the service protocol and in Observatory.
- Fix bug in command completion when subcommands and other completions share common prefixes.
- Rework isolate accounting in the VM object in Observatory. We now create Isolates in getFromMap rather than from IsolateStart events, per se. Rewrite the isolate updating code.
- IsolateStart and IsolateExit events are now owned by the Isolate itself, rather than the vm.
- Return the actual result in pause/resume/etc.
- Add assertion in JSONStream::PrintProperty64 that the result fits in a javascript double. Sigh.
- Stop sending GC events for the service isolate. Add assertions to guard against this happening in the future.
- Misc improvements in error reporting.

Implement in-frame evaluation in the vm service.
Add a notion of 'current frame' and use it across the debugger,
particularly in source-location based commands (break, clear).
Change the expansion logic for frames, so that by default only the
current frame is shown. When a user expands a frame it is now pinned.
Change command line parsing so that internal whitespace is preserved. We need this to properly evaluate expressions with internal whitespace.
Fix a deadlock in the debugger message loop.

--------
VM
Add a new ServiceEvent class in the vm. Rework the event type names.
Add BreakpointAdded, BreakpointResolved, and BreakpointRemoved
service events.
Record the top frame for kIsolateInterrupted and kExceptionThrown
debugger events.
Send a top frame in more Pause* events.
Send breakpoint list with the Isolate response. Remove the
getBreakpoints method from the vm service.
Move Resume events into debugger.cc.
Rework MessageHandler a bit so that we can send PauseStart and
PauseExit notifications.
--------
Observatory
Move some event handler from Application to Isolate.
Rewrite breakpoint tracking code to use the new breakpoint events.
Change run state tracking in Isolate.
Change getFromMap so that it applies updates if the map isn't a ref.
Use getFromMap instead of new ServiceObject in invokeRpc. This
fixes some duplicate ServiceObject problems.

break adds a breakpoint, clear removes it.
Formats:
break - break at current position
break 13 - break at line 13, current script
break 13:20 - break at line 13, col 20, current script
break script.dart:13 - break at line 13, script.dart
break script.dart:13:20 - break at line 13, col 20, script.dart
break main - break at function
break FormatException - break at constructor
break _SHA1._updateHash - break at method
clear supports the same location specifiers.
TAB completion works for all of these formats.
The protocol does not yet support setting column-specific or
function/constructor/method breakpoints. For now we just support
parsing these formats.

Service
- Remove support for old-style service requests.
- Drop 'arguments' from JsonStream and ServiceRequestHandler.
- Json-rpc inspired renaming: command->method, options->params all over.
- Implement getFlagList, setFlag, getObjectByAddress.
- Add helpers PrintMissingParamError and PrintInvalidParamError
to make our error messages more regular.
- Update tests.
- Service_SetSource removed for now. John will resurrect.
Observatory
- Drop all Deprecated 'get' functions. We now use json rpc for everything.
- Drop 'link' and 'relativeLink' from ServiceObject -- they were
ui-specific and they are no longer meaningful anyways. Use 'id' instead.
- New pages: VMPage, FlagsPage, InspectPage, ErrorPage. All urls
used by Observatory are now 'new school' and have a proper
prefix. ErrorPage is the new catch-all.
- Pages now use a Uri instead of a url String. This lets them
grab query parameters more easily.
- SimplePage replaces IsolateSuffixPage.
- We now use gotoLink() or makeLink() to make our navigation
links. gotoLink gets some optional parameters to make it
easier to construct links to ServiceObjects.
- Rework mouse clicks on the heap map to use getObjectByAddress.
- Remove the breakpoint_list. It wasn't working. I'll add it back later.
- Silence logging of getIsolateMetric/getVMMetric.

RunLoop tests were getting wedged trying to communicate with the vm-isolate that was shutdown before a test isolate started up. dartbug.com/22219
This CL:
* ensures that any 'is the service running' checks are done with a lock held.
* Normalizes trace messages printed from the vm-service.

raw_ptr() now returns a const*, and all writes within objects must be routed through a well-defined set of methods on Object.
Note: This also includes writes to non-pointer fields, to enable low-level verification of all writes. Additionally, it allows enforcing a NoGCScope around such writes to protect against moving objects.
Add a bunch of these (now required) NoGCScopes.
