* Revert "Include _http into sky_engine libraries for analyzer (#4154)"
This reverts commit b930f107c3d6648423c42ed10b54f36a92edcbc8.
It is dependent upon the Dart roll, which breaks the engine.
* Revert "Roll dart to ade37f931e90b0fdb8fe16d6bf6f089545da55b6 (#4151)"
This reverts commit 6f1264fb3e11d25a26bc7c44246110ecb5159011.
This Dart roll breaks the engine build on Travis.
This allows analysis to succeed. Otherwise we're seeing errors on List which does not appear as Iterable in core/list.dart unless one has knownledge of EfficientLengthIterable which is defined in internal/internal.dart.
These were forcing our customers to obey these lints, but not all of our
customers like them. We might enable some of these in the future if they have
concrete benefits (e.g., faster generated code when compiling ahead-of-time).
This patch updates _embedder.yaml to enforce the same set of lints as
`flutter analyze`. We're still not enabling strong mode via this
mechanism, but we might consider that in a later patch.

This reverts commit ccd1c5ce1f49c763f9fbce24ad087b46083e4af0, reversing
changes made to d4f97e4fd143b075b52269e22098339941525d8e.
This was requested by @johnmccutchan because this change broke the
analyzer, which only uses SDK version 1.14.1, since that's what we pull
in. He said he'd try again on Monday.
