* Revert "Revert "Run Flutter on iOS and Android with color correct Skia (#3743)" (#3775)"

This reverts commit cfe70e07.

* Enable sRGB on IO thread, too

* Add 4444 as a fallback rendering mode

* Use bare ptr to SkColorSpace (not sk_sp) in PrerollContext

* increase Vulkan GrContext resource cache limits to match android

* [content handler] tune VulkanSurfaceProducer allocation and recycling heuristics

This will make it easier to change mtl into a shared library.

This attempts to make the Canvas API and some related features more
likely to throw a Dart exception than crash when exposed to bad input.

Depends on rolling tonic to
https://fuchsia-review.googlesource.com/c/35742/ which this patch does
not yet do, but I wanted to put it up for review to see if it was even
a reasonable approach.

This allows the shell to be built normally for a Fuchsia host.

If restartInput is called twice in quick succession, then the IME may output
warnings related to usage of the obsolete connection resulting from the first
call.

Currently in `ps` all apps running under the Flutter content handler
show up as `flutter_runner`. This makes them hard to identify. This
change names the process after the final path component URL of the
application that's launched, prefixed with "flutter:".

In theory we could run more than one Flutter application in a single
content handler process, but we don't right now. If we do this logic
would have to change.

* Revert "Fix licenses_lib golden file (#3798)"

This reverts commit d8ac43c3.

* Revert "Remove ParagraphConstriants (#3796)"

This reverts commit 8ccf767f.

* Revert "Reland "Initial integration of libtxt with Flutter alongside Blink." (#3793)"

This reverts commit 3c049219.

ASL was deprecated in iOS 10 and started causing SIGPIPE issues in iOS
10.3. Under the iOS 8 SDK, syslog() stopped working as of iOS 10.3
devices, with the result that ASL stdout/stderr forwarding was the only
means of logging. The engine now builds against the iOS 10 SDK, with
deployment target of iOS 8. Under this SDK, syslog() works correctly
across all supported OS versions.

NOTE: This is a temporary fix to get developers unblocked. While this
does fix the SIGPIPE issue and put iOS logging on par with the Android
solution, the intent is to move to a dedicated communication channel
with flutter_tools that isn't log-based.

Corrects a missed update to the licenses_lib golden file in:
  Remove ParagraphConstriants (#3796)

* Roll Dart dependency

* Update license file

* Removed 'pub get' from the instructions

According to Hixie, 'pub get' is abstracted into flutter packages upgrade, and so there shouldn't be a need to run pub get directly.

* Removed pub get lines entirely.
