This change alters the API for crypto/elliptic to permit different
implementations in the future. This will allow us to add faster,
constant-time implementations of the standard curves without any more
API changes.
As a demonstration, it also adds a constant-time implementation of
P224. Since it's only 32-bit, it's actually only about 40% the speed
of the generic code on a 64-bit system.

Previously, a timeout (in int64 nanoseconds) applied to a granularity
even smaller than one operation: a 100 byte read with a 1 second timeout
could take 100 seconds, if the bytes all arrived on the network 1 second
apart. This was confusing.
Rather than making the timeout granularity be per-Read/Write,
this CL makes callers set an absolute deadline (in time.Time)
after which operations will fail. This makes it possible to
set deadlines at higher levels, without knowing exactly how
many read/write operations will happen in e.g. reading an HTTP
request.

First was, apart from adding tests, a single line of code (to add the
constructor function). Adding SHA512-based hashing to crypto/hmac
required minor rework of the package because of a previously hardcoded
block-size in it's implementation. Instead of using a hash.Hash
generator function the constructor function now uses a crypto.Hash
type, which was extended to expose information about block size.
The only standard library package impacted by the change is
crypto/tls, for which the fix is included in this patch. It might be
useful to extend gofix to include this API change too.

Duplicated fields from URL were dropped so that its behavior
is simple and expected when being stringified and when being
operated by packages like http. Most of the preserved fields
are in unencoded form, except for RawQuery which continues to
exist and be more easily handled via url.Query().
The RawUserinfo field was also replaced since it wasn't practical
to use and had limitations when operating with empty usernames
and passwords which are allowed by the RFC. In its place the
Userinfo type was introduced and made accessible through the
url.User and url.UserPassword functions.
What was previous built as:
url.URL{RawUserinfo: url.EncodeUserinfo("user", ""), ...}
Is now built as:
url.URL{User: url.User("user"), ...}

This CL improves the xml package in the following ways:
- makes its interface match established conventions
- brings Marshal and Unmarshal closer together
- fixes a large number of bugs and adds tests
- improves speed significantly
- organizes and simplifies the code
Fixes#2426.
Fixes#2406.
Fixes#1989.
What follows is a detailed list of those changes.
- All matching is case sensitive without special processing
to the field name or xml tag in an attempt to match them.
Customize the field tag as desired to match the correct XML
elements.
- Flags are ",flag" rather than "flag". The names "attr",
"chardata", etc, may be used to name actual XML elements.
- Overriding of attribute names is possible with "name,attr".
- Attribute fields are marshalled properly if they have
non-string types. Previously they were unmarshalled, but were
ignored at marshalling time.
- Comment fields tagged with ",comment" are marshalled properly,
rather than being marshalled as normal fields.
- The handling of the Any field has been replaced by the ",any"
flag to avoid unexpected results when using the field name for
other purposes, and has also been fixed to interact properly
with name paths. Previously the feature would not function
if any field in the type had a name path in its tag.
- Embedded struct support fixed and cleaned so it works when
marshalling and also when using field paths deeper than one level.
- Conflict reporting on field names have been expanded to cover
all fields. Previously it'd catch only conflicts of paths
deeper than one level. Also interacts correctly with embedded
structs now.
- A trailing '>' is disallowed in xml tags. It used to be
supported for removing the ambiguity between "attr" and "attr>",
but the marshalling support for that was broken, and it's now
unnecessary. Use "name" instead of "name>".
- Fixed docs to point out that a XMLName doesn't have to be
an xml.Name (e.g. a struct{} is a good fit too). The code was
already working like that.
- Fixed asymmetry in the precedence of XML element names between
marshalling and unmarshalling. Marshal would consider the XMLName
of the field type before the field tag, while unmarshalling would
do the opposite. Now both respect the tag of the XMLName field
first, and a nice error message is provided in case an attempt
is made to name a field with its tag in a way that would
conflict with the underlying type's XMLName field.
- Do not marshal broken "<???>" tags when in doubt. Use the type
name, and error out if that's not possible.
- Do not break down unmarshalling if there's an interface{} field
in a struct.
- Significant speed boost due to caching of type metadata and
overall allocation clean ups. The following timings reflect
processing of the the atom test data:
Old:
BenchmarkMarshal 50000 48798 ns/op
BenchmarkUnmarshal 5000 357174 ns/op
New:
BenchmarkMarshal 100000 19799 ns/op
BenchmarkUnmarshal 10000 128525 ns/op

- the main changes are removing the Doc suffix
from the exported types, so instead of
doc.TypeDoc one will have doc.Type, etc.
- All exported types now have a Name (or Names) field.
For Values, the Names field lists all declared variables
or constants.
- Methods have additional information about where they are
coming from.
- There's a mode field instead of a bool to
control the package's operation, which makes
it easier to extend w/o API changes.
Except for the partially implemented new Method type,
this is based on existing code. A clean rewrite is in
progress based on this new API.
