Alexander Markov 172786b906 [VM] Extract simple JSON writer out of VM service-specific JSONStream
The purpose of this refactoring is to provide a convenient way to
write JSON independently of VM service, which is excluded in PRODUCT
build mode.

Ryan Macnak 3d21a46b72 Limit preserialized JSON for timeline events from Dart code to the arguments.
Avoids string copies in C++ and map copies in Dart.

Also remove some vestiages of removed feature that allowed an embedder to add pre-encoded events to the timeline.

Carlo Bernaschina cf4cc1973a Refactor Isolate name format, storage and log
At the moment isolated has a name field which is on the main_port the
only exception is the vm-service isolate.
The name is used just for logging.

The service protocol though uses an extra field called debugger_name,
that at this moment is redundant and is optimized away during
compilation.

BUG=
R=rmacnak@google.com, zra@google.com

This CL:
- Removes the debugger_name in favor of a modifiable name
- Adds to all the log where the name was logged the main_port (that is
  the only real identifier)
- Changes the default format of the isolate name from:
    <script_uri>$<main>
  to:
    <script_uri>:<main>()

- 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).

Natalie Weizenbaum a2fd202314 Use a "jsonrpc" field rather than "json-rpc" in the VM service.
This matches the JSON-RPC 2.0 spec:
http://www.jsonrpc.org/specification#response_object

While this is technically a breaking change, it seems very unlikely that
any consumers were validating this form of the parameter. The
documentation was already inconsistent about whether it was hyphenated,
and the only code likely to be using would be written against the
JSON-RPC 2.0 spec itself, and would reject the old format anyway.
