The adapter will cache a LayoutInflater which refers the current activity, and the ViewModel object will keep alive until activity finished. After activity recreates (e.g. split-screen), it will use the cached LayoutInflater which refers a destroyed activity and crashes. This also is a memory-leak, according to Google's official document, ViewModel shouldn't refer activity. See https://developer.android.com/topic/libraries/architecture/viewmodel
Fix topjohnwu#5413
For example, switching pages in home should only have scale and alpha animations, but a "translate y" animation shows. This is because Data Binding is triggered later (like "in the next frame"), causing the animation runs before view attribute changes.
This commit introduces WindowInsetsHelper class and use it to handle all window insets. With the help of LayoutInflaterFactory from the previous commit, we can control insets behavior by adding our attributes to the XML and anything is done by WindowInsetsHelper class.
As changes are highly coupling, this commit also contains new ItemDecoration for lists, replacing the random combination of padding and empty drawable. And "fixEdgeEffect" extension for RecyclerView, making edge effects respect padding.
This commit fixes the issue of adding single-span items in between full-span items whilst using `StaggeredGridLayoutManager` on recycler view.
Adding such items results in:
```

Affects versions including and prior to androidx.recyclerview:recyclerview:1.2.0-alpha02 (at the time of this commit) and possibly more after that.
This bug is caused by a single fact and that is - array inside of `LazySpanLookup` is not being invalidated and resized correctly when non-full-span item is being added in between of two full-span items. The invalidation however passes on some (high performance) devices so it doesn't necessarily cause issues for _some_ users; others keep getting the same crash over and over again.
Possible fix for anyone reading this, in the hope of fixing the same error, is to copy-paste the `StaggeredGridLayoutManager` and fix the array length before calling `Arrays.fill()`. There's no fix from user's perspective if you need to keep the UI as-is.
We however don't need the UI as-is, so we're instead opting to use LinearLayoutManager until is the issue resolved.

Added pinch in to increase list span count / out to decrease
The setting will be remembered across the whole app (every list that uses Staggered Grid)
Updated indication of whether the policy has root access enabled permitted or not
Displays crossed out app logo if not permitted
All files (that used styles) were refactored to use styles directly so themes can only actually adjust colors
- Elaborate themes would be super hard to maintain and would certainly break over time
Added "endless" scrolling support
- this is done in order to display everything very swiftly and load as user needs it
- for the most part we'll download only ~10 items and load the rest as scroll progresses, this accomplishes the illusion that whole list is being populated
Added sections and updated repo view
