I ran into an issue where `owner.onNavigatingFrom` didn't exist when rendering a view was blocked by the biometric scanner and then user hit the back button to navigate back.
This code simply adds a check to see if `onNavigatingFrom` exists on the owner
fix livesync implementation to be compatible with 3.4 and to replace mainEntry for 4.0 when root is not Frame
some refactoring of page.ios in order to allow showing multiple modal dialogs
Fixed broken unit-tests
ios layout now run only for the innermost viewcontoller
ios layout for viewcontrollers now implemented with constraints
Added ios11 safeAreas layout support
onMeasure back for frame and tab-view so that they won't throw exception if measure is called on them
Page parents layout updated after page is layout so that inner layout flags are correct
iOS layout positioning now respects native properties like automaticallyAdjustsScrollViewInsets, edgesForExtendedLayout, extendedLayoutIncludesOpaqueBars, navigationBar.translucent, tabBar.translucent
Removed frame-tests.ios.ts - those tests are now invalid
Added new layout tests inside page-tests.ios.ts
Commented few asserts in scroll-view-tests
View now expose ios namespace with layoutView method and UILayoutViewController used by page, tab-view and application module
ViewBase now expose viewController property that should be set from all widgets that are using viewcontrollers internally (like Page, Frame, TabView)
ViewBase now sets ios property to either the view returned from createNativeView or to nativeViewProptected
fragment.transitions now use animation/transition start to add fragments to waitingQueue. Before we did it manually in navigate/goBack. This way we can reuse the fragment.transition when calling showDialog. Also when animation/transition ends we check the animation/transition to see if this fragment should be set as current.
Frame expose new loadViewFromEntry method (to load a view from URI)
Frame navigation happens once frame is loaded
Frame now supports Page as a child in XML
Fixed GridLayout row, rowSpan, column, columnSpan properties type
Fixed bug in GridLayout where add/remove of columns/rows won't update the internal state of the grid (backport from android when GridLayout is recycled)
ListView will no longer invalidate layout when cell is removed
Fixed bug in ScrollView ios where effectiveMinWidth/Height was multiplied to density (it is already on device pixels so no need to multiply)
TabView android now calls loaded only on the selected child (not all)
Core refactoring
Add parsers for the background css shorthand property, make ViewBase unit testable in node environment

Use sticky regexes
Simplify some types, introduce generic Parsed<T> instead of & TokenRange
Apply each parser to return a { start, end, value } object
Move the css selector parser to the css/parser and unify types
Add the first steps toward building homegrown css parser
Add somewhat standards compliant tokenizer, add baseline, rework and shady css parsers
Enable all tests again, skip flaky perf test
Improve css parser tokenizer by converting some char token types to simple string
Implement 'parse a stylesheet'
Add gonzales css-parser

Make the style-scope be able to load from "css" and "css-ast" modules
Add a loadAppCss event so theme can be added to snapshot separately from loaded
recycleNativeView filed now accepts: "always" | "never" | "auto". Always will recycle the nativeView no matter if its nativeView or android proprties are accessed. Never will disable recycling. Auto will recycle it only if nativeView and android properties are not accessed.
