Iskander Sharipov e79c39f004 encoding/xml: improve the test coverage, fix minor bugs
Improve the test coverage of encoding/xml package by adding
the test cases for the execution paths that were not covered before.

Since it reveals a couple of issues, fix them as well while we're at it.

As I used an `strings.EqualFold` instead of adding one more `strings.ToLower`,
our fix to `autoClose()` tends to run faster as well as a result.

	name             old time/op    new time/op    delta
	HTMLAutoClose-8    5.93µs ± 2%    5.75µs ± 3%  -3.16%  (p=0.000 n=10+10)
	name             old alloc/op   new alloc/op   delta
	HTMLAutoClose-8    2.60kB ± 0%    2.58kB ± 0%  -0.46%  (p=0.000 n=10+10)
	name             old allocs/op  new allocs/op  delta
	HTMLAutoClose-8      72.0 ± 0%      67.0 ± 0%  -6.94%  (p=0.000 n=10+10)

The overall `encoding/xml` test coverage increase is `88.1% -> 89.9%`;
although it may look insignificant, this CL covers some important corner cases,
like `autoClose()` functionality (that was not tested at all).

And adjust tests as needed.

Not reverting the changes in std that are bootstrapped,

Instead, rewrite 'any' to 'interface{}' in cmd/dist for those directories
when preparing the bootstrap copy.

A few files changed as a result of running gofmt -w
not because of interface{} -> any but because they
hadn't been updated for the new //go:build lines.

Filippo Valsorda a9cfd55e2b encoding/xml: replace comments inside directives with a space
A Directive (like <!ENTITY xxx []>) can't have other nodes nested inside
it (in our data structure representation), so there is no way to
preserve comments. The previous behavior was to just elide them, which
however might change the semantic meaning of the surrounding markup.
Instead, replace them with a space which hopefully has the same semantic
effect of the comment.

Directives are not actually a node type in the XML spec, which instead
specifies each of them separately (<!ENTITY, <!DOCTYPE, etc.), each with
its own grammar. The rules for where and when the comments are allowed
are not straightforward, and can't be implemented without implementing
custom logic for each of the directives.

Simply preserving the comments in the body of the directive would be
problematic, as there can be unmatched quotes inside the comment.
Whether those quotes are considered meaningful semantically or not,
other parsers might disagree and interpret the output differently.

This issue was reported by Juho Nurminen of Mattermost as it leads to
round-trip mismatches. See #43168. It's not being fixed in a security
release because round-trip stability is not a currently supported
security property of encoding/xml, and we don't believe these fixes
would be sufficient to reliably guarantee it in the future.

Filippo Valsorda 4d014e7231 encoding/xml: handle leading, trailing, or double colons in names
Before this change, <:name> would parse as <name>, which could cause
issues in applications that rely on the parse-encode cycle to
round-trip. Similarly, <x name:=""> would parse as expected but then
have the attribute dropped when serializing because its name was empty.
Finally, <a🅱️c> would parse and get serialized incorrectly. All these
values are invalid XML, but to minimize the impact of this change, we
parse them whole into Name.Local.

Leigh McCulloch d70b0ece2f encoding/xml, encoding/json: docs and examples using custom marshalers
Both the encoding/xml and encoding/json packages support custom
marshalers for JSON and XML, as well as the basic encoding.TextMarshaler
and encoding.TextUnmarshaler interfaces, but the docs and examples for
these are missing.

There are docs for how to use encoding.TextMarshaler and
encoding.TextUnmarshaler in encoding/json, but not encoding/xml. There
are no examples for how to use them with either json or xml. This commit
includes docs for encoding/xml and examples for both encoding/json and
encoding/xml.

There is an example using custom marshalers MarshalJSON and
UnmarshalJSON in encoding/json, but not MarshalXML and UnmarshalXML in
encoding/json. These docs are more so necessary for encoding/xml because
the complexities of XML documents is significantly greater than JSON
documents which more often leads to the need for custom marshaling. The
encoding/json package includes an example of how to write a custom
marshaler, and this commit includes the same example for the xml
package.

All examples are mirrored off the existing custom marshaler example in
encoding/json.

Brad Fitzpatrick 2069543bf1 encoding/xml: document HTMLAutoClose and HTMLEntity more
They didn't even have public types, which made them pretty mysterious.

Give them types and reference the Decoder, which uses them.

Also, refer them qualified by their package name in the examples, as
we usually do in example*.go files, which usually use package foo_test
specifically so we can show the package names along with the symbols.

Alberto Donizetti 252ee90971 encoding/xml: simplify slice-growing logic in rawToken
It appears that old code (from 2009) in xml.(*Decoder).rawToken
replicates append's slice-growing functionality by allocating a new,
bigger backing array and then calling copy.

Simplifying the code by replacing it with a single append call does
not seem to hurt performance:

Russ Cox 894869e150 encoding/xml: move unexported const out of exported const block
CL 58210 introduced this constant for reasons I don't understand.
It should not be in the exported const block, which will pollute
godoc output with a "... unexported" notice.

Also since we already have a constant named xmlnsPrefix for "xmlns",
it is very confusing to also have xmlNamespacePrefix for "xml".
If we must have the constant at all, rename it to xmlPrefix.

Leigh McCulloch 65a864a628 encoding/xml: add Marshal doc about name conflicts
The docs for xml.Marshal state that the XML elements name is derived
from one of five locations in a specific order of precedence, but does
not mention that if the field is a struct type and has its name defined
in a tag and in the types XMLName field that an error will occur. This
is documented in the structFieldInfo function but not in the function
documentation, and the existing docs in Marshal are misleading without
this behavior being discussed.

Leigh McCulloch 8db19a4966 all: change github.com issue links to golang.org
The go repository contains a mix of github.com/golang/go/issues/xxxxx
and golang.org/issues/xxxxx URLs for references to issues in the issue
tracker. We should use one for consistency, and golang.org is preferred
in case the project moves the issue tracker in the future.

This reasoning is taken from a comment Sam Whited left on a CL I
recently opened: https://go-review.googlesource.com/c/go/+/73890.

In that CL I referenced an issue using its github.com URL, because other
tests in the file I was changing contained references to issues using
their github.com URL. Sam Whited left a comment on the CL stating I
should change it to the golang.org URL.

If new code is intended to reference issues via golang.org and not
github.com, existing code should be updated so that precedence exists
for contributors who are looking at the existing code as a guide for the
code they should write.
