This patch does:
- Use LSWriteOptimizer
- Remove SessionStorageService since it's unused.
- Move IPC from PContent to PBackground
(by SessionStorageManager{Child, Parent} and SessionStorageCache{Child, Parent}).
- Extract SessionStorageManagerBase and add PBackgroundSessionStorageManager.
- Expose a getter function to get a BackgroundParentManager for top context id
on the parent.
IPC
- Before this patch:
- Copy from parent while loading a document.
- Mark cache entry on the parent process as loaded by the child id.
- Update change on checkpoint.
- Unmark cache entry on the parent process as unloaded for the child id while
the parent actor is destorying.
- After this patch:
- Sync IPC load in the first SessionStorage operation.
- Update change on checkpoint
`BackgroundSessionStorageManager`'s lifecycle on the parent process.
- Create by `SessionStorageManagerParent` and register to the `sManagers`.
- Hold by `SessionStorageManagerParent` and `sManagers`.
- Remove from the `sManagers` while the corresponding `BrowsingContext` is
destructed (on the parent process).
