Setup dependency to use Blink IDL parser (w/ support libs) and latest IDLs.

Setup dependency to use Blink IDL parser (w/ support libs) and latest IDLs.

BUG=

[terry, 2014-08-05 16:51:55]

Checking in DEPS before rest of code to use Blink's IDL parser, Python libs for
new parser, and latest roll of IDLs for dart:libraries (e.g, dart:hmtl, etc.).

Checking in sooner - Emily needs CSS property files in core/css/*.in.

lgtm. thank you, Terry.

How much bigger / slower does this make a regular Dart checkout?  It's pulling
in a lot of stuff (e.g,, C++) that we don't need.

An alternative is to do something like third_party/WebCore below, where we copy
only the files in Blink we need somewhere under the Dart repo and sync in that
pre-filtered branch instead (updated via tools/dom/idlsync.py back in the old
days).

I realize there is a lot of unused stuff but it seems overall relatively small -
adds a little more than 10 sec to gclient (first time for entire download). 
It's nice that there is a very simple way to roll forward.

Maybe we could get the Blink folks to change there bindings directory for script
so we don't have to grab all the test stuff too.  I don't know of a way to get
just one file from a directory (bindings/IDLExtendedAttributes.txt) then we'd
only need bindings/scripts.

However, core is were most of the waste is with the .cpp/.h stuff that's
probably a harder sell to re-arrange would be nice if core/idl/* had all the
IDLs and modules/idl/* had all the IDLs.

81M core (used ~1.8M of IDLs used plus css/*.in)
16M modules (~900K of IDLs used)
14M bindings (used scripts/ 1.1M and IDLExtendedAttributes.txt) Rest not needed
(6-7M of tests, v8/custom and dart/custom).

Currently in third_party there is 1.1G (w/o the Chrome stuff we'll add another
.1G w/ third_party/chrome)

Adds about 12 sec to 'gclient sync' (first time)

Sorry for the slow reply on this.

Before, I would typically do this:

  cd third_party # In a regular dart enlistment
  mv WebCore WebCore.svn
  git svn clone -rHEAD https://dart.googlecode.com/svn/third_party/WebCore
  ../../tools/dom/scripts/idlsync.py
  git add *
  git commit -a -m "..."

This would update the IDL files under third_party/WebCore to exactly those in
the latest Dartium - and strip out the large chunk of files we don't need. 
Would this still work for you?  It seems lower impact and not really any more
work to maintain.  The above sequence still seems to do the right thing.
