Lina Cambridge 99b7c7c7de Bug 1482608 - Port the synced bookmarks merger to Rust. r=nika,mak,markh,tcsc ... This commit introduces a Rust XPCOM component, `mozISyncedBookmarksMerger`, that wraps the Dogear crate for merging and applying synced bookmarks. How this works: `SyncedBookmarksMirror.jsm` manages opening the connection, initializing the schema, and writing incoming items into the mirror database. The new `mozISyncedBookmarksMerger` holds a handle to the same connection. When JS code calls `mozISyncedBookmarksMerger::apply`, the merger builds local and remote trees, produces a merged tree, applies the tree back to Places, and stages outgoing items for upload in a temp table, all on the storage thread. It then calls back in to JS, which inflates Sync records for outgoing items, notifies Places observers, and cleans up. Since Dogear has a more robust merging algorithm that attempts to fix up invalid trees, `test_bookmark_corruption.js` intentionally fails. This is fixed in the next commit, which changes the merger to handle invalid structure.
