0081f17f14 archive/{zip,tar}: fix Writer.AddFS to include empty directories
This change modifies the `(*Writer).AddFS` implementation in both `archive/zip`
and `archive/tar` to always write a directory header. This fixes a bug where
any empty directories in the fs were omitted when a zip or tar archive was
created from `AddFS` method.

3d4daa38a7 net: enable multipath TCP by default for listeners
A previous change [1] was introduced to enable MPTCP by default
for both the clients and servers, based on the discussions [2] in
golang#56539, where MPTCP would be an opt-in for a release or
two, and then would become an opt-out.

This change was not accepted at the time because the support for
a few socket options was missing [3]. Now that this support has been
added [4] and backported to stable versions not to block MPTCP
deployment with Go, it sounds like a good time to reconsider the use
of MPTCP by default.

Instead of enabling MPTCP on both ends by default, as a first step,
it seems safer to change the default behaviour only for the server
side (Listeners). On the server side, the impact is minimal: when
clients don't request to use MPTCP, server applications will create
"plain" TCP sockets within the kernel when connections are accepted,
making the performance impact minimal. This should also ease
experiments where MPTCP is enabled by default on the client side
(Dialer).

The changes in this patch consist of a duplication of the mptcpStatus
enumeration to have both a mptcpStatusDial and a mptcpStatusListen,
where MPTCP is enabled by default in mptcpStatusListen, but disabled
by default in mptcpStatusDial. It is still possible to turn MPTCP support
on and off by using GODEBUG=multipathtcp=1.

79ca434ac6 testing: add Chdir
Some tests need to use os.Chdir, but the use is complicated because
 - they must change back to the old working directory;
 - they must not use t.Parallel.

Add Chdir that covers these cases, and sets PWD environment variable
to the new directory for the duration of the test for Unix platforms.
Unify the panic message when t.Parallel is used together with t.Setenv
or t.Chdir.

Add some tests.

b67443459a spec: clarify prose for embedded struct fields
The spec says that an embedded field must be specified
as a type name (or a pointer to a type name). This is
explicit in the prose and the FieldDecl syntax.

However, the prose on promoted methods required a named
type (originally the term used for a "defined type").
Before the introduction of alias types, type names could
only refer to named/defined types, so the prose was ok.

With the introduction of alias types in Go 1.9, we
distinguished between defined types (i.e., types given
a name through a type declaration) and type aliases
(types given an alternative name), and retired the notion
of a named type since any type with a name (alias type
and defined type) could be considered a "named type".

To make things worse, with Go 1.18 we re-introduced the
notion of a named type which now includes predeclared
types, defined types, type parameters (and with that
type aliases denoting named types).

In the process some of the wording on method promotion
didn't get updated correctly. At attempt to fix this
was made with CL 406054, but while that CL's description
correctly explained the intent, the CL changed the prose
from "defined type" to "named type" (which had the new
meaning after Go 1.18), and thus did not fix the issue.

This CL fixes that fix by using the term "type name".
This makes the prose consistent for embedded types and
in turn clarifies that methods of embedded alias types
(defined or not) can be promoted, consistent with the
implementation.

While at it, also document that the type of an embedded
field cannot be a type parameter. This restriction has
been in place since the introduction of type parameters
with Go 1.18 and is enforced by the compiler.

Fixes #66540.
For #41687.

ff2a57ba92 cmd/go/internal/test: add 'tests' vet check to 'go test' suite
(Second attempt at CL 529816 (f1d6050), reverted in
CL 571695 (1304d98) due to broken longtest builder.)

The tests analyser reports structural problems in test
declarations. Presumably most of these would be caught by
go test itself, which compiles and runs (some subset of) the
tests, but Benchmark and Fuzz functions are executed less
frequently and may benefit more from static checks.

A number of tests of "go vet" needed to be updated, either
to avoid mistakes caught by the analyzer, or to suppress
the analyzer when the mistakes were intended.

Also, reflect the change in go test help message.

879ace1434 net/http: keep Content-Encoding in Error, add GODEBUG for ServeContent
This reverts the changes to Error from CL 571995, and adds a
GODEBUG controlling the changes to ServeContent/ServeFile/ServeFS.

The change to remove the Content-Encoding header when serving an error
breaks middleware which sets Content-Encoding: gzip and wraps a
ResponseWriter in one which compresses the response body.

This middleware already breaks when ServeContent handles a Range request.
Correct uses of ServeContent which serve pre-compressed content with
a Content-Encoding: gzip header break if we don't remove that header
when serving errors. Therefore, we keep the change to ServeContent/
ServeFile/ServeFS, but we add the ability to disable the new behavior
by setting GODEBUG=httpservecontentkeepheaders=1.

We revert the change to Error, because users who don't want to include
a Content-Encoding header in errors can simply remove the header
themselves, or not add it in the first place.

77cc7fbc84 doc/next: add motivation and details links for range-over-func iterators
The "Changes to the language" section at the top of the release notes
will likely ultimately include more explanation about iterators, or at
least, the Go project will likely publish additional introductory
material on iterators on the blog and so on.

As a perhaps temporary step given current interest, this CL updates the
release notes with two additional links for details and motivation.

The new package documentation for the iter package is up-to-date,
precise, and also more accessible than the language spec, while the 2022
pre-proposal GitHub discussion starts with perhaps the most compelling
motivation writeup so far. (We purposefully include "2022" in the text
to help illustrate this was not the result of an overly hasty process).

We also update the target of the existing language spec reference to be
closer to the new material.

For #61405.
