Go 1.4 and earlier accepted mysql://x@y(z:123)/foo
and I don't see any compelling reason to break that.
The CL during Go 1.5 that broke this syntax was
trying to fix#11208 and was probably too aggressive.
I added a test case for #11208 to make sure that stays
fixed.
Relaxing the check did not re-break #11208 nor did
it cause any existing test to fail. I added a test for the
mysql://x@y(z:123)/foo syntax being preserved.
Fixes#12023.

RawPath is a hint to the desired encoding of Path.
It is ignored when it is not a valid encoding of Path,
such as when Path has been changed but RawPath has not.
It is not ignored but also not useful when it matches
the url package's natural choice of encoding.
In this latter case, set it to the empty string.
This should help drive home the point that clients
cannot in general depend on it being present and
that they should use the EncodedPath method instead.
This also reduces the impact of the change on tests,
especially tests that use reflect.DeepEqual on parsed URLs.

Historically we have declined to try to provide real support for URLs
that contain %2F in the path, but they seem to be popping up more
often, especially in (arguably ill-considered) REST APIs that shoehorn
entire paths into individual path elements.
The obvious thing to do is to introduce a URL.RawPath field that
records the original encoding of Path and then consult it during
URL.String and URL.RequestURI. The problem with the obvious thing
is that it breaks backward compatibility: if someone parses a URL
into u, modifies u.Path, and calls u.String, they expect the result
to use the modified u.Path and not the original raw encoding.
Split the difference by treating u.RawPath as a hint: the observation
is that there are many valid encodings of u.Path. If u.RawPath is one
of them, use it. Otherwise compute the encoding of u.Path as before.
If a client does not use RawPath, the only change will be that String
selects a different valid encoding sometimes (the original passed
to Parse).
This ensures that, for example, HTTP requests use the exact
encoding passed to http.Get (or http.NewRequest, etc).
Also add new URL.EscapedPath method for access to the actual
escaped path. Clients should use EscapedPath instead of
reading RawPath directly.
All the old workarounds remain valid.

Using IPv6 link-local addresses to make connections between on-link
nodes is useful for small distributed applications but it requires zone
identifiers to distinguish a correct IP link. It's the same for
transports using URI for destination discovery such as HTTP, WebSocket.
This change allows Parse, ParseRequestURI functions and String method of
URL to parse/return a literal IPv6 address followed by a zone identifier
within a URI as described in RFC 6874.
Fixes#6530.
