There are a few different places in the code that escape
possibly-problematic characters like < > and &.
This one was the only one missing &, so add it.
This means that if you Marshal a string, you get the
same answer you do if you Marshal a string and
pass it through the compactor. (Ironically, the
compaction makes the string longer.)
Because html/template invokes json.Marshal to
prepare escaped strings for JavaScript, this changes
the form of some of the escaped strings, but not
their meaning.

The old code was caching per-type struct field info. Instead,
cache type-specific encoding funcs, tailored for that
particular type to avoid unnecessary reflection at runtime.
Once the machine is built once, future encodings of that type
just run the func.

Additionally, the numbers seem stable now at ~52 MB/s, whereas
the numbers for the old code were all over the place: 11 MB/s,

against the best I saw the old code do.

Original CL by rsc (11916045):
The motivation for disallowing them was RFC 4180 saying
"The last field in the record must not be followed by a comma."
I believe this is an admonition to CSV generators, not readers.
When reading, anything followed by a comma is not the last field.

Phrases like "returns whether or not the image is opaque" could be
describing what the function does (it always returns, regardless of
the opacity) or what it returns (a boolean indicating the opacity).
Even when the "or not" is missing, the phrasing is bizarre.
Go with "reports whether", which is still clunky but at least makes
it clear we're talking about the return value.
These were edited by hand. A few were cleaned up in other ways.

I want to think more carefully about this.
We put this in because Marshal encoded named []byte but Unmarshal rejected them.
And we noticed that Marshal's behavior was undocumented so we documented it.
But I am starting to think the docs and Unmarshal were correct and Marshal's
behavior was the problem.
Rolling back to give us more time to think.

json: unmarshal types that are byte slices.
The json package cheerfully would marshal
type S struct {
IP net.IP
}
but would give an error when unmarshalling. This change allows any
type whose concrete type is a byte slice to be unmarshalled from a
string.
Fixes#5086.

In practice, rejecting an entire structure due to a single invalid byte
in a string is just too picky, and too hard to track down.
Be consistent with the bulk of the standard library by converting
invalid UTF-8 into UTF-8 with replacement runes.

The first identifier in an Object Identifer must be between 0 and 2
inclusive. The range of values that the second one can take depends
on the value of the first one.

If there are no tags, the rules are the same as before.
If there is a tagged field, choose it if there is exactly one
at the top level of all fields.

they all pass as is. The new tests only work with the new code.

The old code was incorrect and also broken. It passed the tests by accident.
The new algorithm is:
1) Sort the fields in order of names.
2) For all fields with the same name, sort in increasing depth.
3) Choose the single field with shortest depth.
If any of the fields of a given name has a tag, do the above using
tagged fields of that name only.

If two fields have the same name but different explicit name spaces,
treat as non-conflicting. This allows parsing common XML formats
that have ns1:tag and ns2:tag in the same XML element.
Fixes#4691.
Allow setting the default name space for unadorned tags, by
writing to Decoder.DefaultSpace. This allows turned the job of
parsing common XML formats that have tag and ns2:tag in the
same XML element into the first case by setting DefaultSpace="ns1".

Attach name space to attributes when encoding.
