* Fix docs

Also includes minor other javadoc and formatting fixes.

Add additional class names and style to components and error indicators to distinguish different error levels.

Vaadin 8 implementation of #9816. Cherry picked changes and added compatibility package component changes and tests.

Resolves #3139

When child components are removed from a
VerticalLayout/HorizontalLayout, do not remove other children from the
DOM if no other hierarchy changes are made.

Fixes #7713

Adds a v7 AbstractFieldConnector for the compatibility package
Remove dependency from core to old AbstractField

Full Name of defect:
Regression: Table column jumps when table is shown and table is contained in a layout

Regression is a outcome of  change due to #12672.

No TB4 test because problem happens too fast to be caught.

Full defect name: Empty space on page after expanded component - incorrect height calculation in Chrome

Layout:
[
Panel (auto x auto) [
Grid (auto x auto)
]
AnyComponent (100% x 100%)
<EMPTY SPACE>

Also sleep() was removed from tests BaseLayoutExpandTest and
BaseAddReplaceMoveTest

'Aborting layout after 100 passes.' is caused by LayoutManager falling
into a loop on rounding fractional layout slot sizes up and down while
trying to fit layout's content in the space available. LayoutManager
round always up, that causes this issue with IE9+ and Chrome. This
change helps LayoutManager to round fractional sizes down for browsers
that causes problems if rounded up.

Browsers may fall into the loop especially with a zoom level other than
100%. Not with any zoom level though. Problematic zoom level varies by
browser. OrderedLayoutExpandTest uses zoom levels other than 100%. Test
for Chrome is the only one that really is able to reproduce error
without the fix. IE9/10 would too, but the zoom level could not be set
exactly to the required 95% for IE. Test works best as a regression test
for other browsers.

Reverting the previous fix to caption measurement, it caused a leak with
the listeners.

Changed implementations and APIs to use the non-deprecated Element class
wherever possible without breaking backwards compatibility.
* Methods defined in interfaces have not been touched.
* Return types have only been changed methods that should have no
existing third party callers (i.e. private, internal or @since 7.2)
* For methods that third party code might have overridden, the method
has been deprecated in favor of a new method that just delegates to the
old method.
* For methods that can't reasonably be overridden by third party code
(i.e. private, final, static, internal or @since 7.2), the parameter
type has been changed without retaining the old method.

This is the first step towards eliminating usage of the class. Reasoning
about upcoming steps will be easier when it's clear which class
"Element" refers to.

measured
