This also makes path/filepath.Walk more consistent between
Windows and POSIX platforms.
According to
https://pubs.opengroup.org/onlinepubs/9699919799.2013edition/basedefs/V1_chap04.html#tag_04_12
symlinks in a path that includes a trailing slash must be resolved
before a function acts on that path.
POSIX defines an lstat function, whereas the Win32 API does not, so
Go's os.Lstat should follow the (defined) POSIX semantics instead of
doing something arbitrarily different.
CL 134195 added a test for the correct POSIX behavior when os.Lstat is
called on a symlink. However, the test turned out to be broken on Windows,
and when it was fixed (in CL 143578) it was fixed with different Lstat
behavior on Windows than on all other platforms that support symlinks.
In #50807 we are attempting to provide consistent symlink behavior for
cmd/go. This unnecessary platform difference, if left uncorrected,
will make that fix much more difficult.
CL 460595 reworked the implementation of Stat and Lstat on Windows,
and with the new implementation this fix is straightforward.
For #50807.
Updates #27225.

Prior to this change (as of CL 143578), our stat function attempted to
resolve all reparse points as if they were symlinks.
This results in an additional call to CreateFile when statting a
symlink file: we use CreateFile once to obtain the reparse tag and
check whether the file is actually a symlink, and if it is we call
CreateFile again without FILE_FLAG_OPEN_REPARSE_POINT to stat the link
target. Fortunately, since symlinks are rare on Windows that overhead
shouldn't be a big deal in practice.
Fixes #42919.

Some file operations, notably Stat and Mkdir, special cased their
behavior when operating on a file named "NUL" (case-insensitive).
This check failed to account for the many other names of the NUL
device, as well as other non-NUL device files: "./nul", "//./nul",
"nul.txt" (on some Windows versions), "con", etc.
Remove the special case.
os.Mkdir("NUL") now returns no error. This is consonant with the
operating system's behavior: CreateDirectory("NUL") succeeds, as
does "MKDIR NUL" on the command line.
os.Stat("NUL") now follows the existing path for FILE_TYPE_CHAR devices,
returning a FileInfo which correctly reports the file as being a
character device.
os.Stat and os.File.Stat have common elements of their logic unified.

Go documentation style for boolean funcs is to say:
// Foo reports whether ...
func Foo() bool
(rather than "returns true if")
This CL also replaces 4 uses of "iff" with the same "reports whether"
wording, which doesn't lose any meaning, and will prevent people from
sending typo fixes when they don't realize it's "if and only if". In
the past I think we've had the typo CLs updated to just say "reports
whether". So do them all at once.
(Inspired by the addition of another "returns true if" in CL 146938
in fd_plan9.go)
Created with:
$ perl -i -npe 's/returns true if/reports whether/' $(git grep -l "returns true iff" | grep -v vendor)

Stat uses Windows FindFirstFile + CreateFile to gather symlink
information - FindFirstFile determines if file is a symlink,
and then CreateFile follows symlink to capture target details.
Lstat only uses FindFirstFile.
This CL replaces current approach with just a call to CreateFile.
Lstat uses FILE_FLAG_OPEN_REPARSE_POINT flag, that instructs
CreateFile not to follow symlink. Other than that both Stat and
Lstat look the same now. New code is simpler.
CreateFile + GetFileInformationByHandle (unlike FindFirstFile)
does not report reparse tag of a file. I tried to ignore reparse
tag altogether. And it works for symlinks and mount points.
Unfortunately (see https://github.com/moby/moby/issues/37026),
files on deduped disk volumes are reported with
FILE_ATTRIBUTE_REPARSE_POINT attribute set and reparse tag set
to IO_REPARSE_TAG_DEDUP. So, if we ignore reparse tag, Lstat
interprets deduped volume files as symlinks. That is incorrect.
So I had to add GetFileInformationByHandleEx call to gather
reparse tag after calling CreateFile and GetFileInformationByHandle.

os.Stat implementation uses instructions described at
https://blogs.msdn.microsoft.com/oldnewthing/20100212-00/?p=14963/
to distinguish symlinks. In particular, it calls
GetFileAttributesEx or FindFirstFile and checks
either WIN32_FILE_ATTRIBUTE_DATA.dwFileAttributes
or WIN32_FIND_DATA.dwFileAttributes to see if
FILE_ATTRIBUTES_REPARSE_POINT flag is set.
And that seems to worked fine so far.
But now we discovered that OneDrive root folder
is determined as directory:
c:\>dir C:\Users\Alex | grep OneDrive
30/11/2017 07:25 PM <DIR> OneDrive
c:\>
while Go identified it as symlink.
But we did not follow Microsoft's advice to the letter - we never
checked WIN32_FIND_DATA.Reserved0. And adding that extra check
makes Go treat OneDrive as symlink. So use FindFirstFile and
WIN32_FIND_DATA.Reserved0 to determine symlinks.

When we write a cached test result, we now also write a log of the
environment variables and files inspected by the test run,
along with a hash of their content. Before reusing a cached test result,
we recompute the hash of the content specified by the log, and only
use the result if that content has not changed.
This makes test caching behave correctly for tests that consult
environment variables or stat or read files or directories.

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.

Currently windows Stat uses combination of Lstat and Readlink to
walk symlinks until it reaches file or directory. Windows Readlink
is implemented via Windows DeviceIoControl(FSCTL_GET_REPARSE_POINT, ...)
call, but that call does not work on network shares or inside of
Docker container (see issues #18555 ad #19922 for details).
But Raymond Chen suggests different approach:
https://blogs.msdn.microsoft.com/oldnewthing/20100212-00/?p=14963/
- he suggests to use Windows I/O manager to dereferences the
symbolic link.
This appears to work for all normal symlinks, but also for network
shares and inside of Docker container.
This CL implements described procedure.
I also had to adjust TestStatSymlinkLoop, because the test is
expecting Stat to return syscall.ELOOP for symlink with a loop.
But new Stat returns Windows error of ERROR_CANT_RESOLVE_FILENAME
= 1921 instead. I could map ERROR_CANT_RESOLVE_FILENAME into
syscall.ELOOP, but I suspect the former is broader than later.
And ERROR_CANT_RESOLVE_FILENAME message text of "The name of
the file cannot be resolved by the system." sounds fine to me.

This changes the os package to use the runtime poller for file I/O
where possible. When a system call blocks on a pollable descriptor,
the goroutine will be blocked on the poller but the thread will be
released to run other goroutines. When using a non-pollable
descriptor, the os package will continue to use thread-blocking system
calls as before.
For example, on GNU/Linux, the runtime poller uses epoll. epoll does
not support ordinary disk files, so they will continue to use blocking
I/O as before. The poller will be used for pipes.
Since this means that the poller is used for many more programs, this
modifies the runtime to only block waiting for the poller if there is
some goroutine that is waiting on the poller. Otherwise, there is no
point, as the poller will never make any goroutine ready. This
preserves the runtime's current simple deadlock detection.
This seems to crash FreeBSD systems, so it is disabled on FreeBSD.
This is issue 19093.
Using the poller on Windows requires opening the file with
FILE_FLAG_OVERLAPPED. We should only do that if we can remove that
flag if the program calls the Fd method. This is issue 19098.

Windows has a limit of 260 characters on normal paths, but it's possible
to use longer paths by using "extended-length paths" that begin with
`\\?\`. This commit attempts to transparently convert an absolute path
to an extended-length path, following the subtly different rules those
paths require. It does not attempt to handle relative paths, which
continue to be passed to the operating system unmodified.
This adds a new test, TestLongPath, to the os package. This test makes
sure that it is possible to write a path at least 400 characters long
and runs on every platform. It also tests symlinks and hardlinks, though
symlinks are not testable with our builder configuration.

Current code doesn't follow this manner.
For example, 'sameFile' exists in "file_unix.go",
"stat_plan9.go" and "types_windows.go".
The CL address that problem by following rules:
* readdir family => dir.go, dir_$GOOS.go
* stat family => stat.go, stat_$GOOS.go
* path-functions => path_$GOOS.go
* sameFile => types.go, types_$GOOS.go
* process-functions => exec.go, exec_$GOOS.go
* hostname => sys.go, sys_$GOOS.go

cmd and runtime were handled separately, and I'm intentionally skipped
syscall. This is the rest of the standard library.
CL generated mechanically with github.com/mdempsky/unconvert.

The tree's pretty inconsistent about single space vs double space
after a period in documentation. Make it consistently a single space,
per earlier decisions. This means contributors won't be confused by
misleading precedence.
This CL doesn't use go/doc to parse. It only addresses // comments.
It was generated with:
$ perl -i -npe 's,^(\s*// .+[a-z]\.) +([A-Z]),$1 $2,' $(git grep -l -E '^\s*//(.+\.) +([A-Z])')
$ go test go/doc -update

Old style. Make it compliant with our code review comments document.
Also, make WriteString's return parameter named 'n', not 'ret', for
consistency.
Noticed during another documentation review.
