ObjectBox C and C++ 6.0.0 beta

Lead feature: P2P Mesh Sync

• WebAssembly (WASM): the library is now built as part of releases;
  also updated the Emscripten toolchain, reducing the binary size significantly
• Admin: modernized user interface based on Vue.js 3 and Material Design 3
• Admin: optimized pages now loading faster
• Android: log messages now use the logcat tag "ObjectBox" (previously "Box")
• Breaking: removed previously deprecated functions from the C API:
  • obx_debug_log() and obx_debug_log_enabled(): use obx_log_level_set() and obx_log_level_get() instead
  • obx_qb_contains_key_value_string(): use obx_qb_equals_key_value_string() instead
  • obx_qb_any_equals_string(): use obx_qb_contains_element_string() instead
• Breaking: removed previously deprecated members from the C++ API:
  • Options(OBX_model*) constructor: use Options().model(model) instead
  • Store::debugLog() and Store::debugLogEnabled(): use Store::logLevelSet() and Store::logLevelGet() instead
  • String vector query condition contains(): use containsElement() instead
  • Sync::client(store, url, credentials): use the builder instead,
    e.g. Sync::client(store).url(url).credentials(credentials).build()
• Internal fixes and improvements

Sync

• New Mesh Sync API: peer-to-peer (P2P) synchronization between sync clients without a central server
  • C: configure via obx_mesh_opt_*() and obx_sync_opt_mesh();
    access the running mesh via obx_sync_mesh() and obx_mesh_*()
  • C++: new MeshOptions and Mesh classes, SyncBuilder::mesh() and SyncClient::mesh()
• C++: fixed SyncClient::removeFilterVariable() removing all filter variables instead of the given one
• C++: fixed registering a SyncClientErrorListener (the error callback was bound to the wrong listener object)
