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.

This CL adds targets to the GN build that build the standalone Dart VM
without the observatory, and with dart:io enabled but with most of the
functionality stubbed out as UNIMPLEMENTED(). It also adds a simple
eventhandler for Fuchsia for implementing Timers.

- Explicitly allow connections from localhost/127.0.0.1 and the server's ip address and host name.
- This has the negative effect of breaking our Dartium work flow, so, I've added the "--disable-service-origin-check" flag to the standalone embedder which disables the security check.

- cache builtin_lib in IsolateData so that the cached value can be used withouit having to call Builtin::LoadAndCheckLibrary which creates new string objects everytime it is called.

- Cleanups to the embedder's Dart sources for the service isolate. This lets us stop keeping a local copy in the mojo and flutter trees.
- Let the VM know Observatory's server address.

Remove -fdata-section again from the Linux build configuration: It prevented
some optimizations in gcc and clang - fewer things were recognized as constants.
Add const to pointers/arrays in some places to help compilers with determining
what is a constant. A common pattern is strlen of a string literal const char*,
or an array of function pointers.
Tested with gcc 4.8.4 / clang 3.4 and improves code qualtiy + reduces binary size.

- Include the embedder's portion of the service isolate's Dart code in precompiled snapshots. Swap it in as the root library when running precompiled instead of loading from source.
- Make linter happy with gen_snapshot.
- Fix profiler to consider Instructions in the VM isolate may have their corresponding Code in the regular isolate.
- Make non-functional service RPCs fail cleanly instead of crashing.

- Add flag to enable zlib compression of resources to create_resource.py
- Enable flag for Observatory resources
- Use 'dart:io' ZlibCodec to decompress resources when first loaded into service isolate.
- Dart executable (debug, macos) goes from 15,460b to 13,752b

2) Move observatory from runtime/bin/vmservice/observatory to runtime/observatory
3) Add two tools scripts:
- tools/run_pub.py (runs pub before SDK is built)
- tools/obs_tool.py (helper for get, build, and deploy stages)
4) Build Observatory with runtime:
- pub get --offline
- pub build
- deploy
5) Build artifacts are now in standard output directory, for example, out/DebugIA32/observatory.
6) Add a new 'dart_boostrap' host target (no snapshot, no observatory) that can be used as the Dart executable to run pub when building Observatory. This is behind a build.py flag --use-bootstrap-for-observatory because:
- It is only necessary on older Linux distributions that are incompatible with the prebuilt Dart testing executable.
- running pub build with the boostrap Debug build is significantly slower.
7) Detect if the prebuilt executable doesn't work and automatically switch to the 'dart_bootstrap' executable. Also, warn the user and provide a Wiki link with more information.

- 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.

- Reset the state that a class is being currently parsed.
- Move the deployed polymer app to a location where it is not
being overwritten by the tools.
- Do not rely on Dart SDK binaries being in your path.
- Check for errors when invoking dart2js as part of build.dart.

This CL is largely a move/rename of the sources so they are laid out in the standard directory layout (the other layout is no longer necessary with the single html and js file deployed output). Buried inside the rename is the out/ directory which contains the observatory deployed as a single js file + html/img assets.
bootstrap_css DEPS have been updated already.
