This change follows the recommendations of ISO 8601 per
https://en.wikipedia.org/wiki/ISO_8601#cite_note-26
which states
ISO 8601:2004(E), ISO, 2004-12-01, "4.2.2.4 ...
the decimal fraction shall be divided from the integer
part by the decimal sign specified in ISO 31-0, i.e.
the comma [,] or full stop [.]. Of these, the comma
is the preferred sign."
Unfortunately, I couldn't directly access the ISO 8601 document
because suddenly it is behind a paywall on the ISO website,
charging CHF 158 (USD 179) for 38 pages :-(
However, this follows publicly available cited literature, as well
as the recommendations from the proposal approval.

Add support for channels in subster.typ(). Add new test file chans.go.
To support assignability of bidirectional channel args to directional
channel params, I needed to type check generic calls after they are
instantiated. (Eventually, we will create separate functions to just do
the assignability logic, so we don't need to call the old typechecker in
this case.) So, for generic calls, we now leave the call as OCALL (as a
signal that the call still needs typechecking), and do typecheck.Call()
during stenciling.
Smaller changes:
- Set the type of an instantiated OCLOSURE node (and not just the associated
OFUNC node)
- In instTypeName2, filter out the space that types2.TypeString inserts
after a common in a typelist. Our standard naming requires no space
after the comma.
- With the assignability fix above, I no longer need the explicit
conversions in cons.go.

This change moves the call of sysMap from (*mheap).sysAlloc into
(*mheap).grow, so we only sysMap what we're going to use in the near
future (thanks to the curArena mechanism). The purpose of this change is
to better support systems with strict overcommit rules which generally
accept reserved memory but not prepared memory (see malloc.go for exact
descriptions of these states).
This move requires changing linearAlloc to only optionally map memory.
In one case, with mheap.heapArenaAlloc, we do want it to map memory. But
now in the other case, with mheap.arena, we don't, because we want grow
to take care of it.
The risk with this change is we may make more syscalls than before on
systems with 64 MiB arenas, but because heap growth is relatively rare
this is unlikely to be a noticable issue. We also bound the amount of
syscalls made by only extending curArena (and thus mapping) by
pallocChunkPages*pageSize which is 4 MiB.

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.

The favicon.ico and robots.txt files have been with us in the root

had content for the golang.org website, which could be run locally.
Since these files were at the root of the website, they were added
to the corresponding location in the GOROOT tree—at the root.
In 2018, work started on factoring out golang.org website content
and code into a new golang.org/x/website repository (issue 29206).
The favicon.ico and robots.txt files were copied to x/website repo,
but some more work needed to be done before they would be picked up
and served when golangorg was executed in module mode. That work is
done by now (CL 293413 and CL 293414).
The scope of the godoc tool has also been reduced to just serving
Go package documentation and not the website (issue 32011), so it
can provide its own favicon.ico as needed (CL 300394).
This means these two files have no more use and can be deleted.
