/**
 * Map-like representation of url search parameters, based on
 * [URLSearchParams](https://url.spec.whatwg.org/#urlsearchparams) in the url living standard,
 * with several extensions for merging URLSearchParams objects:
 *   - setAll()
 *   - appendAll()
 *   - replaceAll()
 *
 * This class accepts an optional second parameter of ${\@link QueryEncoder},
 * which is used to serialize parameters before making a request. By default,
 * `QueryEncoder` encodes keys and values of parameters using `encodeURIComponent`,
 * and then un-encodes certain characters that are allowed to be part of the query
 * according to IETF RFC 3986: https://tools.ietf.org/html/rfc3986.
 *
 * These are the characters that are not encoded: `! $ \' ( ) * + , ; A 9 - . _ ~ ? /`
 *
 * If the set of allowed query characters is not acceptable for a particular backend,
 * `QueryEncoder` can be subclassed and provided as the 2nd argument to URLSearchParams.
 *
 * ```
 * import {URLSearchParams, QueryEncoder} from '\@angular/http';
 * class MyQueryEncoder extends QueryEncoder {
 *   encodeKey(k: string): string {
 *     return myEncodingFunction(k);

 *
 *   encodeValue(v: string): string {
 *     return myEncodingFunction(v);
