- [x] Add arguments `rootLibUri` and `packagesUri` to the reload service rpc. These allow the uri of the root library and the .packages files to be overridden.
- [x] When pairing libraries during reload, support the base url changing.

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for reasons that are no longer valid, and sets us up to add some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.

For blobs, put all four pieces into a single file with a header describing their offsets.
For dynamic libraries, move the vm isolate and isolate pieces into the dynamic library as additional read-only sections.
Automatically detect if the script argument is an app snapshot and initialize the VM appropriately, similar to automatic detection of script snapshots.

We now check all of the scripts which make up a library. If any
script is modified, then we consider that library to be modified. We
also consider any library which imports a modified library to be
modified. To propagate this info efficiently, we build and discard
the imported-by graph when beginning a reload.
The embedder must provide a FileModifiedCallback in order to support
the detection of modified scripts.
In order to detect changes to package: libraries, we have modified the
embedder interface to provide the resolved url when possible, so that
we don't need to re-resolve package uris when checking for reload.
This change is incompatible and all embedders will need to be updated.
We now support a "force" flag when reloading sources. This causes all
libraries to be reloaded regardless of whether the underlying scripts
have been updated.

- [x] The first caller of the tag handler blocks, recursive callers queue work and exit.
- [x] Use a NativeMessageHandler to receive I/O results from the service isolate.
- [x] Preserve load error message format.
- [x] Move packages map into service isolate.
- [x] Wire up Todd's native URI code.

Adds Dart_DefaultCanonicalizeUrl() to the dart embedding api.
Motivation:
As we try to get source reloading working for the standalone embedder, things get simpler if an isolate doesn't run Dart code while it is loading Dart code. We intend to solve this by moving the embedder tag handler calls to the service isolate. But making a blocking rpc into the service isolate whenever a url needs to be canonicalized during parsing seems like it would slow things down and make things complicated. By moving canonicalization into C++, we avoid this.

This is a cut of the work that Todd and I collaborated on in the reload branch.
In this CL, we've dropped the loader port hacks, in other words, on stack reloading in the standalone embedder does not work yet.
- [x] Support for hot reloading of isolate source code
- [x] Unit test harness and many tests
- [x] Service protocol and Observatory support
- [x] Product build does not include support for hot reloading.

API changes:
- Remove isolate specific Timeline APIs.
- Remove Dart_EmbedderTimelineGetTimeline callback.
- Add Dart_TimelineEvent so that arbitrary trace events can be added.
Internal changes:
- Remove isolate specific streams which were never used or controllable from outside the VM.

- Add three new embedder hooks registered with Dart_SetEmbedderTimelineCallbacks
- Dart_EmbedderTimelineStartRecording
- Dart_EmbedderTimelineStopRecording
- Dart_EmbedderTimelineGetTimeline
- Add unit test for record start / stop notification.
- Add unit test for get timeline.
This should allow Flutter to remove their hacked up timeline service RPCs.

- Add Dart_ShouldPauseOnStart, Dart_SetShouldPauseOnStart, Dart_IsPausedOnStart, Dart_SetPausedOnStart, Dart_ShouldPauseOnExit, Dart_SetShouldPauseOnExit, Dart_IsPausedOnExit, Dart_SetPausedOnExit to query and control pause on start / exit from outside of the default message handler.
- Add Dart_HandleMessages to process all regular messages from outside the default message handler.
- Allow per isolate overriding of pause on start / pause on exit flags.
- Set the resume_request bit when resuming from isolate start / exit.
- Clear the resume_request bit in the default message handler.
- Rename MessageHandler fields and accessors.
- Rename Isolate::Resume to Isolate::SetResumeRequest.

The error propagation is delayed until the native function returns.
This should simplify error handling in embedder code and avoid failing
to propagate an error, which is a common failure.

- Make --gen/run-precompiled-snapshot take a directory to use for the snapshot pieces.
- Throw on Platform.executeable to prevent tests from becoming fork-bombs.
- Update status files so 'dart_precompiled' is generally expected to behave the same as 'vm'.
Currently multitests will fail unless run with --jobs=1 because the test harness assigns them the same temporary directory.
Running this also requires a great deal of space. My out directory is 380G.

Three types of fixes:
1. Remove redundant const_cast
2. Remove const_cast by adding const when appropiate.
3. Remove const_cast by removing const (e.g. places where we call free with it)
For now I only fixed places where the fix is local enough - i.e. does not require
changed a large amount of code.
