Resolves #2823
These changes allow using reqwest without
serde(and evensynfor a good number of features).First commit wraps the
RequestBuilder::query()andRequestBuilder::form()methods in new feature flags:query,form. These features are enabled by default, so the change would only impact anyone settingdefault-features = false.Second commit removes the use of
serde_jsonfor WASM header parsing, instead using JS array access.Technically this still pulls in
serdedue to a bug inurl, but that should be resolved in the next release.
