https://github.com/jasongin/nodejs/commit/dcc50445a364664586164f42f9250732bd372982
This patch adds the support to emit a trace event by using a comma-separated
list of categories, so that the trace event will be emitted if there is at least
one category is enabled in the categories list.

We only need included categories list, excluded categories list will only work
if we use regular expression in categories list, which is not supported in V8.

Escape sequences may now be written to a trace file (previously,
any string with a valid escapable character would fail a check).

Also, string properties are now surrounded with quotes.

1. The third parameter of strncpy should be the length of source string.
2. Value contains " should be valid.

V8 has had a trace event macro interface for while, but without a tracing
controller a standalone V8 would be unable to collect traces.

This CL introduces a complete Tracing Controller system for V8.
It is fully function except that it does not yet store trace event args.

This CL has a few components,
The tracing controller itself, contributed by the author of this CL
The Trace config (including the parser), contributed by lpy@
The Trace Object, Trace Writer, and Trace Buffer are all contributed by rksang@

BUG=v8:4561
LOG=N

The original CL was failing the V8 Arm Builder:
https://build.chromium.org/p/client.v8.ports/builders/V8%20Arm%20-%20builder/builds/2456
and the V8 Mips Builder:
https://build.chromium.org/p/client.v8.ports/builders/V8%20Mips%20-%20builder/builds/2506

The failure is due to undefined behavior of CHECK_EQ of 2 const char*

Fix in patch #1
