getJSON built its URL with new URL and then overwrote the host and
path, which dropped a base path in a self-hosted apiOrigin; postJSON,
putJSON and the file and thumbnail download URLs joined strings. All of
them now go through one function next to ApiClient that accepts a path
with or without a leading slash and an origin with or without a
trailing slash or base path, and percent-encodes query parameters. A
path containing "?" or "#" is rejected.
