Adopted from https://github.com/vaadin/flow/pull/8567

This patch adds a compatibility version of FileTypeResolver.

* ColorTextField, helper methods, and regex for validating and handling text input

* Refactored structure to avoid creating new component for validation

* Style to adapt to error indicator

* Tests for validating input in ColorPickerPreview component's TextField

* Merge branch 'master' into colorpicker_validation

* Fix path to server class

* Fix test: Submit the new value

* Fix test: ignore Phantom JS

* Fix hsl+hsla validation patterns to accept '%', test value tweaking

* Merge branch 'master' of github.com:vaadin/framework into colorpicker_validation

* Fix: remove warning when color is updated from elsewhere

* Revisions: input validation only once, Logging level WARN

* Revisions: unit tests for color pattern matching

* Revisions: moved parsing to utility class, tests for parsing all accepted input formats

* Fixed import in tests, comments

* Revisions: Logger as constant, ignore utility class in serialization test

* Corner case tests

* Revisions: protected method for parsing error text, fix to test

* Revisions: NPE fix

Also removes dependency on junit.framework.TestCase .

Also includes some other minor cleanup.

* Refactor common methods of InMemoryHierarchicalDataProvider and ListDataProvider to a single interface
* Rename HierarchyData and InMemoryHierarchicalDataProvider, introduce HasHierarchicalDataProvider
* Additionally adds a helper method for recursive constructing
TreeData with a child item provider.

Use bnd-maven-plugin instead of maven-bundle-plugin and helper class, and
add support for publishing static resources such as themes and widgetsets.

* Initial HierarchicalDataProvider for TreeGrid
* Initial in-memory hierarchical data implementation
* TreeGrid declarative support

Fixes #8611, Fixes #8620

To ensure the resource is automatically closed

* Fix java packaging order (#106)

Closes vaadin/archetypes#113

* Use proper UTF-8 encoding for Content-Disposition filenames (#19527) (#6607)

* Enable changing the backing bean for BeanItem (#4302) (#77)

When storing a bean to the database, you typically get a new and updated
bean instance back. By allowing to change the bean instance, we make it
possible to just update the single BeanItem instance which can be used
in many places.

* Make AtmospherePushConnection methods public (#7973)

There is no sensible way to use a custom version of APC, so protected
access does not help in any way to access the underlying resource and/or
connected UI.

* Use correct indexes in multiselect checkboxes after removing rows (#8072)

Fixes #8011

* Fix removal of hidden Grid columns (#8071)

Fixes #8018

* Call error handler for exceptions in UI.init() (#8055)

Fixes #4995

* Render font icon correctly on the 'more' menu item (#8126)

* Render font icon correctly on the 'more' menu item

Fixes #8125

* Reopen Grid details on attach, fixes #8015 (#8074)

Fixes #8015

* Fix broken Grid tests after picking changes from 7.7.7

Removed duplicate setDetailsVisible calls from onDetach

* Correctly detach components in merged cells when a static row is removed (#8142)

Fixes #8140

* Fix BeanBinderPropertySet to not deserialize into multiple instances

Git on OS X seems to have problems with changing between branches with
the old and new casing of the two json related files. Changing back to
the old names to avoid issues when changing branches.

API change from:
    public static Iterable<ClientConnector> getAllChildrenIterable(final ClientConnector connector)
to
    public static Iterable<? extends ClientConnector> getAllChildrenIterable(final ClientConnector connector)

avoids creating wrappers in case the component has either no subcomponents
or no extensions. This covers the vast majority of components.

The null element and the empty JSONArray are frequently created and used
as temporary objects to be encoded by the json encoder. Because they are
never manipulated it is possible to reuse the same empty element again
and save a significant amount of temp objects.
This also helps jsonEquals, which then can return faster due to:
if (fieldValue == referenceValue) return true

jsonEquals does not need to check the referenceValue for JSONobject.NULL.
The invoking code makes sure this never happens.
Boolean and Integer values are very often and much more efficiently
compared directly instead of using toString.
