- one change counter for the virtual flash (writes, close, remove, rename,
mkdir, format, NVS commit): the page persists IDBFS when it moves
- HTTPClient through a single hook, wadaHttpRequest() (still offline), replies
served from memory, so map tiles over fetch() is one function later
- WADA_DEFAULT_DATA_DIR; settimeofday stub and pthread_exit task end under
Emscripten (no C++ exceptions there)
