Cirrus puts the PR description and commit message in environment
variables.
These messages tend to have non ASCII characters sometimes (like
emojis), which triggers a Gradle bug (gradle/gradle#3117) resulting
in Gradle crashing without a helpful error message.

The real solution to this problem should be fixing the Gradle bug.
The better workaround on the Flutter side would be to set a UTF8 locale
on the Cirrus machine, but I have yet figured out how to do it.
For now to avoid more people from hitting this I'm working around by
temporarily unsetting the Cirrus environment variables with the PR
description and commit message.

A non ASCII character to make sure it works: 😄

* Ensure all errors thrown by image providers can be caught by developers.

Add an `onError` parameter to the ImageCache.putIfAbsent method.
In the event that an error is thrown when resolving an image, catch if
this parameter is provided. Use the onError parameter to ensure that all
errors thrown are forwarded to the ImageStream error channel instead of
directly into the void.

Unique patch numbers are mainly useful for canary and A-B testing, but otherwise complicate things and can now be omitted.

* Collect devfs stats for better analytics

* Fix fields initialization

* Fix lints

flutter/engine#7307 changes the engine side of embedded UIView to only
reject gestures when the framework sends a `rejectGesture` message, so
that gesture resolution can done after a touch sequence has ended (see
PR description for flutter/engine#7307 for more details).

This change makes the framework send a `rejectGesture` message to the
engine when a UiKitView rejects a gesture.

I'm planning to land this PR before the engine side change, so right now
it swallows the exception thrown if there is no engine implementation
for `rejectGesture` (which keeps us with the current behavior). After
this change lands I'll land the engine PR, and then clean up the part
that swallows the exception.
