- [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.

When gen_snapshot encounters a url that has been remapped with the --url_mapping command line argument it rewrites the library's url to be the mapped url before canonicalization. The new C++ API only does canonicalization with respect to the library's url (as returned by Dart_LibraryUrl) which is insufficient for gen_snapshot. The correct long-term fix is to alter the new C++ API to allow for the base url to be passed in directly rather than indirectly via Dart_LibraryUrl.
This CL just restores some deleted code and has gen_snapshot work like it did before. The standalone embedder still uses the C++ API during loading.

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.

Previously we would compile in implementaitions of native calls for
IO functions that would never be used. This CL provides implementations
that throw a Dart exception if they're called by mistake. It also uses
a DART_IO_DISABLED preprocessor define to clean up the build files and
check that we're not including code we shouldn't.

Also some style cleanups.
Decided to fix these leaks by using Dart_ScopeAllocate
instead of malloc and new. Leaks are noted in the CL.
I haven't finished looking over all the code in
//runtime/bin yet, but this CL was getting big.

Implements SecurityContext.setTrustedCertificates in terms of the new
function. This requires setTrustedCertificates to return a Future,
and removing the `directory` named argument as it is not possible to
implement with BoringSSL without blocking IO.

- 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.

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.

- API breakage: Dart_IsolateBlocked, Dart_IsolateUnblocked -> Dart_ThreadDisableProfiling, Dart_ThreadEnableProfiling.
- Remove IsolateProfilerData.
- Move thread at blocking call count from isolate to thread.
- Always interrupt threads unless they are blocked.
- We can no longer count "idle" ticks.
- Only record sample if thread is the current mutator of an isolate.
- Refactor ThreadInterrupterCallback to ensure that Thread* is valid.
Threads are only ever sent signals if ThreadInterruptsEnabled is true. Which is controlled by two functions:
void DisableThreadInterrupts();
void EnableThreadInterrupts();

- Provide a new callback to Dart_Initialize that will be called when the service isolate needs the Observatory assets
- Move asset management code out of embedder and into common dart:_vmservice
- Use the tar format as the archive format
- Add build script to generate .cc file containing the archive
- Add a simple tar parser to service isolate
This makes it possible for embedders to not bake Observatory into their executable but instead load it off disk or over the network. The standalone embedder still links Observatory into the executable.

In a next step, the i/o will be moved to the service isolate so that not all isolates have to import dart:io.
Fallout from this change:
1) Loading has become a tad slower. Will have to investigate why.
2) Errors that happen during loading (file not found, compilation error in an imported library) are no longer reported at the offending import clause. This can be fixed later if necessary by passing the import clause source location to the library tag handler.
