A fix for the globals.h TODO in libplatform.

A fix for the globals.h TODO in libplatform.

The fix is simple, we make our version of globals.h called macros.h with
the necessary macro used by libplatform files.

Hey Jochen, was something along these lines you were thinking?

[jochen (gone - plz use gerrit), 2014-01-28 13:14:00]

i think it would be preferable to have a src/base/ or something where shared
headers are instead of duplicating the definitions

Will we have a src/base/globals.h, I suppose. I'll cook something like this and
ping you back.

Hey Jochen, does this (PS3) works for you?

Hmmm, actually I don't think it makes sense in its current form: What is the
advantage of moving globals.h around? Even if at some point in the future we
re-use Chrome's base/, globals.h is very v8-specific. Perhaps I am
misunderstanding things here...

Benedikt?

I don't think the goal is to prepare for using chromium's base, at least not
anytime soon.

I want to get to a point were libplatform is a separate library which an
embedder can use (instead of providing their own implementation). Existing code
should either move to libplatform/ and v8 depends on it via the v8-platform.h
header, or, if both v8 and libplatform want to use it, to some base/ or shared/
or common/ or whatever library
