UIScene notifications are the correct way to track window focus on
iOS 13.0+, because the Key Window API is scene-level on iOS 13.0+,
but we need to maintain support for iOS 12 and earlier.
Implementation strategy:
- iOS 13.0+: Use UIScene notifications (DidActivate/WillDeactivate)
- iOS 12 and earlier: Keep existing UIWindow notifications as fallback
- Add runtime version checks to select the appropriate API
Key changes in os_ios.m:
- Add @available(iOS 13.0, *) checks
- Register both notification types with conditional logic
- Ensure proper cleanup of observers when moving between windows

Now, it's possible to launch one Gio app using a custom URI scheme, such as `gio://some/data`.
This feature is supported on Android, iOS, macOS and Windows, issuing a new transfer.URLEvent,
containing the URL launched. If the program is already open, one transfer.URLEvent will be
sent to the current app.
Limitations:
On Windows, if the program listen to schemes (compiled with `-schemes`), then just a single
instance of the app can be open. In other words, just a single `myprogram.exe` can
be active.
Security:
Deeplinking have the same level of security of clipboard. Any other software can send such
information and read the content, without any restriction. That should not be used to transfer
sensible data, and can't be fully trusted.
Setup/Compiling:
In order to set the custom scheme, you need to use the new `-schemes` flag in `gogio`, using
as `-schemes gio` will listen to `gio://`.
If you are not using gogio you need to defined some values, which varies for each OS:
macOS/iOS - You need to define the following Properly List:
```
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>yourCustomScheme</string>
</array>
</dict>
</array>
```
Windows - You need to compiling using -X argument:
```
-ldflags="-X "gioui.org/app.schemesURI=yourCustomScheme" -H=windowsgui"
```
Android - You need to add IntentFilter in GioActivity:
```
<intent-filter>
<action android:name="android.intent.action.VIEW"></action>
<category android:name="android.intent.category.DEFAULT"></category>
<category android:name="android.intent.category.BROWSABLE"></category>
<data android:scheme="yourCustomScheme"></data>
</intent-filter>
```
That assumes that you still using GioActivity and GioAppDelegate, otherwise more
changes are required.
Events are routed to a new app.Events, which are not linked to a specific window.

Up until now, the iOS part has relied on a tool such as gogio to
synthesize a main function. This change adds support for running direcetly
in exe mode, while retaining support for embedded Gio in C programs.

This is mostly a refactor, but there are two user-visible effects:
- Window.NextEvent may be called even after DestroyEvent is returned.
- Window.Invalidate always wakes up a blocking NextEvent, even when a
FrameEvent cannot be generated.
As a nice side-effect, X11, Wayland and Wasm no longer require separate
goroutines for their window loops.

Commit c0c25b777 replaced the synchronizing of the display link callback
from a sync.Map to a cgo.Handle. However, the change didn't take into
account the lifecycle issues: a callback may happen just as the cgo.Handle
is freed, leading to a misuse crash.
This change restores the sync.Map synchronization, which avoids the
lifecycle issue.

UTF8String is lossy in the presence of nul (\x00) runes.
While here, don't CFRelease the input to nsstringToString; leave it
up to the caller.

For mixing native UI with Gio UI, the UIViewController is sometimes
needed, not just the UIView. This change replace the View field of
ViewEvent with ViewController.

The app and app/internal/wm packages are tightly coupled, requiring
quite a bit of forwarding types, values and constants from the internal
package to export it. Further, no other package imports package wm.
This change merges the two packages.
While here, drop the pre-Go 1.14 SIGPIPE workaround.
