CopyBuffer allocates a 32k buffer when no buffer is available.
Allocate these buffers from a sync.Pool.
This removes an optimization where the copy buffer size was
reduced when the source is a io.LimitedReader (including the
case of CopyN) with a limit less than the default buffer size.
This change could cause a program which only uses io.Copy
with sources with a small limit to allocate unnecessarily
large buffers. Programs which care about the transient
buffer allocation can avoid this by providing their own buffer.

All APIs in the now-deprecated io/ioutil package have a direct
replacement in either the io or os package with the same signature,
with the notable exception of ioutil.ReadDir, as os.ReadDir has a
slightly different signature with fs.DirEntry rather than fs.FileInfo.
New code can easily make use of []fs.DirEntry directly,
but existing code may need to continue using []fs.FileInfo for backwards
compatibility reasons. For instance, I had a bit of code that exposed
the slice as a public API, like:
return ioutil.ReadDir(name)
It took me a couple of minutes to figure out what the exact equivalent
in terms of os.ReadDir would be, and a code sample would have helped.

This patch allows to zerocopy using MultiReader.
This is done by MultiReader implementing WriterTo.
Each sub reader is copied using usual io copy helper and thus use
WriterTo or ReadFrom with reflection.
There is a special case for when a subreader is a MultiReader.
Instead of using copyBuffer which would call multiReader.WriteTo,
multiReader.writeToWithBuffer is used instead, the difference
is that the temporary copy buffer is passed along, saving
allocations for nested MultiReaders.
The workflow looks like this:
- multiReader.WriteTo (allocates 32k buffer)
- multiReader.writeToWithBuffer
- for each subReader:
- is instance of multiReader ?
- yes, call multiReader.writeToWithBuffer
- no, call copyBuffer(writer, currentReader, buffer)
- does currentReader implements WriterTo ?
- yes, use use currentReader.WriteTo
- no, does writer implement ReadFrom ?
- yes, use writer.ReadFrom
- no, copy using Read / Write with buffer
This can be improved by lazy allocating the 32k buffer.
For example a MultiReader of such types:
MultiReader(
bytes.Reader, // WriterTo-able
bytes.Reader, // WriterTo-able
bytes.Reader, // WriterTo-able
)
Doesn't need any allocation, all copy can be done using bytes.Reader's
internal data slice. However currently we still allocate a 32k buffer
for nothing.
This optimisation has been omitted for a future patch because of high
complexity costs for a non obvious performance cost (it needs a benchmark).
This patch at least is on par with the previous MultiReader.Read
workflow allocation wise.

Do not require the byte or rune unread by the call to match the last
return from ReadByte or ReadRune, since in practice the
implementations of these methods (especially ReadByte) may also unread
bytes from other Read-style methods without reporting an error.
Explicitly allow the Seek-like behavior implemented by bytes.Reader
and bufio.Reader, which can “unread” bytes that were never actually
read.
Explicitly allow ReadByte or ReadRune to return an error after a call
to a non-ReadByte or non-ReadRune operation respectively.
(In practice, implementations today allow very liberal calls to
ReadByte and tend to be more strict about ReadRune, but it seems
simpler to keep the two definitions completely parallel.)
Like CL 349054, this is techincally a breaking change, but given the
long-standing behavior of the implementations in the Go standard
library (such as strings.Reader, bytes.Buffer, and bufio.Reader),
I believe it falls under the “specification errors” exception to the
Go 1 compatibility policy.

Use “or” instead of “and” to describe error behavior.
On error, nearly all Seeker implementations in the Go repo return
0 instead of “the new offset”. (Arguably on error “the new offset”
is the same as the previous offset, but some Seeker implementations
don't have that offset readily available.)
Don't claim that “any positive offsite is legal”.
In practice, most of the Seeker implementations within the Go standard
library do not allow “[s]eeking to any [arbitrary] positive offset”:
some reject all out-of-bounds offsets, and some reject only a subset
that happen to overflow some underlying representation. Since some
positive offsets may be rejected, we cannot claim that seeking to
those offsets “is legal”. However, to avoid invalidating existing
Seeker implemetations we must not require an implementation to reject
invalid positive offsets either.
This is technically a breaking change, since callers of Seek are no
longer allowed to assume that a Seek resulting in an arbitrary
positive offset will succeed. However, since basically none of the
existing implementations actually conformed to the documented behavior
I believe this falls under the “specification errors” exception to the
Go 1 compatibility policy.

Calling fs.Sub with the result of fs.Sub multiple times creates a deep
call stack for Open and other methods. Enhance the fs.FS returned by
fs.Sub to implement fs.SubFS and reduce the call stack.

Emphasize ReadDirFile. It isn't really optional,
and all filesystems have at least one directory (".").
The remaining two additional interfaces are optimizations.
Call them that.

Rejecting backslash introduces problems with presenting
underlying OS file systems that contain names with backslash.
Rejecting backslash also does not Windows-proof the syntax,
because colon can also be a path separator. And we are not
going to reject colon from all names. So don't reject backslash
either.
There is a similar problem on Windows with names containing
slashes, but those are more difficult (though not impossible)
to create.
Also document and enforce that paths must be UTF-8.
Fixes#44166.
