Adds RequiredExecutionEnvironment and License fields and renames some
bundles (SymbolicName) for backwards compatibility.

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

Fixes #8682

Partial fix for #8682

Fixes #8722

Synchronises parts of compatibility package code to match 7.7
Picks suitable patches for 8 code as well

* 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

* Fixed touch scrolling issue in Surface and WP devices (#18737)

Fixed by using pointerevents instead of touchevents when the browser is
IE11,
or Edge. Also added touch-action: none; css rules into escalator.css to
prevent
default touch behaviour on IE11 and Edge. Does not affect IE8 to IE10
browsers,
behaviour on those will stay the same as before the fix.

No new unit tests since we do not have automatic touch testing
possibilities yet.
Please test manually with Surface: IE11 and Edge, use for example

Vaadin 7 compatiblity fields still use setRequired via AbstractField (legacy).
Public setRequiredIndicator is added to AbstractField, AbstractMultiSelect and AbstractSingleSelect.
Internally it is still handled on AbstractComponent & -Connector level.
Changes the declarative syntax, required -> required-indicator-visible.
