This change introduces manifest properties that control when dynamic patches are downloaded and installed in the application lifecycle.
Application developer can choose whether between install on restart, install on resume, or immediate forced install of dynamic patches.
Minor refactoring of dynamic patching code.
- Changes naming of manifest properties to be consistent with documentation.
- Moves methods from inner class to outer class to make them more reusable.
Unique patch numbers are mainly useful for canary and A-B testing, but otherwise complicate things and can now be omitted.
Also, always append .zip to patch download URL. This obviates the need to configure redirects on the server when not using patch numbers.
* Namespaces have been updated to reflect the move from //flutter/sky/shell to //flutter/shell.
* shell/BUILD.gn file has been split into smaller GN files for each subcomponent of the shell (common, GPU, diagnostic, testing).
* GN dependencies have been rewritten to stop exposing common shell dependencies as public. Duplicates have also been removed.
* GPU subcomponent has been updated make it more suitable for Vulkan integration.
* The GLFW backend has been resurrected.
