/*
 * Parses an URI and fills string chunks with locations of the respective
 * uri components within the input uri string. NULL pointers will be
 * ignored.
 *
 * General syntax:
 *
 *     [scheme://[user_info@]]host[:port][/path][?query][#fragment]
 *
 * Example:
 *
 *     foo.com:80
 *     tcp://foo.com:1234
 *     http://foo.com:80/bar?baz=1
 *     https://user:pw@foo.com:443/blah
 *
 * `path` will include the leading slash. `query` won't include the leading `?`.
 * `host` can contain embedded colons if surrounded by square brackets in order
 * to support IPv6 literal addresses.
 *
 *
 * Returns 0 on success, -1 on error.
