i.e. #ifndef VM_WHATEVER -> #ifndef RUNTIME_VM_WHATEVER

This lets us remove a hack from the PRESUBMIT.py script that existed
for reasons that are no longer valid, and sets us up to add some
presubmit checks for the GN build.

- [x] Report the reload error synchronously from the _reloadSources RPC.
- [x] Add sticky reload error to an isolate so we can report the error.
- [x] Remove redundant 'OnStackReload'.
- [x] Fix a bug where a class could have a field added but we wouldn't reject it.

John McCutchan 1a4c2005cc DevFS initial implementation.
This cl implements an experimental filesystem maintained in the vm, called dart-devfs.  This will allow service protocol users to read and write source files while the vm is running.  This is needed for the reload support for flutter.

This is a cut of the work that Todd and I collaborated on in the reload branch.

- [x] Support for hot reloading of isolate source code
- [x] Unit test harness and many tests

John McCutchan 32abe2ce55 Stream blocks of timeline events over the service protocol. Can be used to monitor long running programs without buffering all events inside the VM.
- Rename TimelineEventStreamingRecorder to TimelineEventCallbackRecorder. Note that this should only be used for tests.

- Add 'Timeline' service event stream.
- Send a 'TimelineEvents' event on the 'Timeline' stream whenever a TimelineEventBlock is finished and the 'Timeline' stream is subscribed to.

- Simple service protocol test.

John McCutchan d77d376124 Replace intptr_t with TokenDescriptor
- Use TokenDescriptor instead of intptr_t for all token positions.
- Use TokenDescriptor in raw_object instead of int32_t.
- TokenDescriptor is a POD with an int32_t (this shrinks the size of AST and IR nodes by 32-bits on 64-bit architectures).

There are some cleanups I plan on doing as a follow up CL:

- Replace TokenDescriptor::value() with TokenDescriptor::TokenPos()

turnidge@google.com 2757d6e686 Rework error handling in the service protocol and in Observatory.
In JSON RPC, error results and regular results are distinguished structurally.  We now do this in the service protocol instead of returning a regular result with the "Error" type.

VM:

- Add PrintError method to JSONStream.  Use this to generate all errors in the service protocol.

- Fix some bugs with "limit" parameter handling.

- Change return value for heap rpcs when they find a collected/expired reference.

- Update tests.

Observatory:

- Add app.handleExceptions -- this is a widely-used exception handler that puts up a notification when there is an uncaught/unexpected exception.  Added a top-level zone catch that uses this handler, as well as explicit uses of this handler at various points in the code.  Most pages use this implicitly or explictly, except for the debugger page, which displays exceptions in the console.

[ General rule, when a function returns a Future, generally let the error pass through.  If a function does async work but doesn't return the Future, then it should handle errors explicitly by calling app.handleExceptions, etc. ]

- Fixed notifications.  They were generally broken.  Some hard-coded type names needed to be fixed, some hacks needed to be removed.

- Add a new class RpcException and a variety of subclasses which capture the error cases when making an rpc.

- Redo refresh buttons so their callbacks return Futures instead of taking a "done" closure.  Cleaner.  Allows us to move error handling outside of the callback.

- Drop ServiceError, ServiceException and the associated views.

- Redo notifications so that event and exception notifications are supported.

- No longer null out the vm when it is disconnected.

- Remove notifications when we visit the vm-connect page.  Only show the "Proceeding will lose current page" dialog when we aren't on the vm-connect page already.

- Improve error message on cpu profile page when profiling is disabled on the VM.

- Allow variables to wrap on debugger page.

- Make eval-box and eval-link tolerant of errors during rpc.  Make the errors display nicely.

- When a breakpoint is marked "not possible", make sure it disappears.  This got broken during script view refactor.

- Drop vm's errors and exceptions streams.  No longer needed.

turnidge@google.com d9f65329c3 Do not JSON encode the 'result' of a service rpc.
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.

getBreakpoints method from the vm service.

Move Resume events into debugger.cc.

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.

turnidge@google.com d554f4fbfe Finish moving service protocol to json rpc.
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.

rmacnak@google.com 27b99b257c Don't double-escape strings in the VM Service, and don't use \u0000 to determine the string length.
This makes characters above ASCII to display as themselves in Observatory, strings with \u0000 in the middle not to be truncated, and avoids a bug in the previous escaping where a non-ASCII character in the last position would have its escaped representation cut off.
