72fdecafc0 spec: add a link to Allocation section in section on append built-in
If needed, the built-in function append allocates a new underlying
array. While we (probably) don't want to specify exactly how much
is allocated (the prose is deliberately vague), if there's more
space allocated than needed (cap > len after allocation), that
extra space is zeroed. Use an explicit link to the section on
Allocation which explicitly states that newly allocated memory
is zeroed.

Fixes #56684.

753ad5e1d5 spec: document that trailing comma is valid after index in index expressions
At parse time we don't know if a[i] is an index expression or a
type (or function) instantiation. Because instantiations accept
a list of type arguments, and argument lists permit a trailing
comma, a[i,] is either an instantiation or index expression.

Document that a trailing comma is permitted in the syntax for
index expressions.

For comparison, the same problem arises with conversions which
cannot be distinguished from function calls at parse time. The
spec also permits a trailing comma for conversions T(x,). The
grammar adjustment is the same (see line 5239).

Fixes #55007.

7a00f973a5 archive/tar, archive/zip: disable ErrInsecurePath by default
This change is being made late in the release cycle.
Disable it by default. Insecure path checks may be enabled by setting
GODEBUG=tarinsecurepath=0 or GODEBUG=zipinsecurepath=0.
We can enable this by default in Go 1.21 after publicizing the change
more broadly and giving users a chance to adapt to the change.

For #55356.

f41fdc1267 doc/go1.20: document changes to the loopclosure vet analysis
Address the release notes TODO regarding the loopclosure analyzer,
documenting the new warning for parallel subtests.

In doing so, choose a structure for the vet section, opting for h4
headings. In recent years, we have used either h4 headings or simple
paragraphs to document vet changes. This year, I thought it worthwhile
to put the timeformat and loopclosure changes into separate sections.

Also document the improvements to reference capture detection introduced
in CL 452615.

07c57aff5d all: use Go 1.17.13 for bootstrap
Previously we used Go 1.17, but we realized thanks to tickling
a pre-Go1.17.3 bug that if we are going to change the bootstrap
toolchain that we should default to the latest available point release
at the time we make the switch, not the initial major release, so as
to avoid bugs that were fixed in the point releases.

This CL updates the default search locations and the release notes.

Users who run make.bash and depend on finding $HOME/sdk/go1.17
may need to run

	go install golang.org/dl/go1.17.13@latest
	go1.17.13 download

to provide a Go 1.17.13 toolchain to their builds.

f2c7e78592 spec: document operations which accept []byte|string constrained types
Pre-1.18, as special cases, the built-in operations append and copy
accepted strings as second arguments if the first argument was a byte
slice. With Go 1.18, these two built-ins as well as slice expressions
rely on the notion of core types in their specification.

Because we want to permit slice expressions, append, and copy to
operate on (1st or 2nd operands) that are type parameters restricted
by []byte | string (and variations thereof), the simple notion of
core type is not sufficient for these three operations. (The compiler
already permits such more relaxed operations).

In the section on core types, add a paragraph and examples introducing
the (artificial) core type "bypestring", which describes the core type
of type sets whose underlying types are []byte or string. Adjust the
rules for slice expressions, append, and copy accordingly.

Also (unrelated): Adjust prose in the only paragraph where we used
personal speech ("we") to impersonal speech, to match the rest of
the spec.

Fixes #52859.

0dffda1383 spec: clarify "slice of bytes" and "slice of runes" through examples
The spec section on conversions uses the terms "slice of bytes" and
"slice of runes". While not obviously clear, what is meant are slice
types whose element types are byte or rune types; specifically the
underlying types of the slices' element types must be byte or rune.

Some of this was evident from the examples, but not all of it. Made
this clearer by adding more examples illustrating various permitted
conversions.

Note that the 1.17 compiler did not accept the following conversions:

        string([]myByte{...})
        string([]myRune{...})
        myString([]myByte{...})
        myString([]myRune{...})

(where myByte, myRune, and myString have underlying types of byte,
rune, and string respectively) - it reported an internal error.
But it did accept the inverse conversions:

        []myByte("...")
        []myRune("...")
        []myByte(myString("..."))
        []myRune(myString("..."))

The 1.18 compiler made those conversions symmetric and they are now
permitted in both directions.

The extra examples reflect this reality.

Fixes #23814.

4703546a29 spec: add missing optional type arguments after TypeName in syntax
Types may be generic, so each occurrence of a TypeName may be
followed by optional type arguments. Add the missing syntactic
(EBNF) factor.

The syntax of type names followed by type arguments matches the
syntax of operand names followed by type arguments (operands may
also be types, or generic functions, among other things). This
opens the door to factoring out this shared syntax, but it will
also require some adjustments to prose to make it work well.
Leaving for another change.

Fixes #53240.

bc2e961cf4 reflect: deprecate (Slice|String)Header
As discussed in CL 401434 there are substantial misuses of these in the
wild, and they are a potential source of unsafety even for code that
does not use them directly.

We should either keep them as-is and document when/how they can be used
safely, or deprecate them so that uses will eventually die out.

After some discussion, it was decided to deprecate them outright.
Since the docs already mentioned that they may be unstable across
releases, it should be possible to get rid of them completely later on.
