Does not yet migrate hasIdeviceId since that results in a cascade of
breaking interface changes that's significant enough for a separate
patch.

* Revert "Test installation status when ideviceid is not installed (#10254)"

This reverts commit 0e5d4a87.

* Revert "Partial rollback of #10204 (#10256)"

This reverts commit b291bf5d.

Ensure that flutter doctor returns a partial installation status when
ideviceid is not installed.

This broke Fuchsia as they haven't updated to Dart 1.24 yet :(

Our emulator detection was based on a simple heuristic that was
failing for the Samsung Galaxy S8. Any heuristic is flawed since
Android devices can report whatever they want to adb, but this
change attempts to tighten the detection by listing known models
(by their ro.hardware property). Again, these values could be
spoofed by emulator system images, but it's less likely to be
an issue than with our previous (and fall-back) heuristic.

This helps to debug encoding issues that are believed to only happen for certain locales (see https://github.com/flutter/flutter/issues/10198 fo example).

DO NOT SUBMIT until Dart SDK has been bumped (https://github.com/flutter/flutter/pull/10110) as this depends on new API.

Maybe this will make the test work in the device lab...

Eliminate the implementation detail of which function is called to
trigger vibration on iOS, instead report the vibration constant.

Also note that not all iOS devices support haptic feedback (e.g., older
iPod touch devices).

IDEA users sometimes want to create multiple Flutter modules
in the same IDEA project. See discussion:
https://github.com/flutter/flutter-intellij/issues/1014

In this case, we will actually have pairs of modules,
one for Flutter and one for Android. Renaming the
android module to make the relationship obvious.

But, don't delete the old file yet to avoid breaking
existing users. We can do that after the next
Flutter plugin release.

This will get tested once we turn on fatal errors for dartdocs.
We can't do that yet because of upstream failures.

On failure to configure a mock VM service, we get a useful exception in
setUpAll(). This change prevents an additional failure in tearDownAll()
that provides no additional useful diagnostic info.
