And then revert the bootstrap cmd directories and certain testdata.
And adjust tests as needed.
Not reverting the changes in std that are bootstrapped,
because some of those changes would appear in API docs,
and we want to use any consistently.
Instead, rewrite 'any' to 'interface{}' in cmd/dist for those directories
when preparing the bootstrap copy.
A few files changed as a result of running gofmt -w
not because of interface{} -> any but because they
hadn't been updated for the new //go:build lines.
Fixes #49884.

Go 1.17 introduced an unnecessary change to when a zip's data descriptor
is read for file entries, how it is parsed and how the crc32 field is
used.
Before Go 1.17, the data descriptor was read immediately after a file
entry's content. This continuous read is a pattern existing applications
have come to rely upon (for example, where reads at specific offsets
might be translated to HTTP range requests).
In Go 1.17, all data descriptors are immediately read upon opening the
file. This results in scattered and non-continuous reads of the archive,
and depending on the underlying reader, might have severe performance
implications. In addition, an additional object is now initialized for
each entry, but is mostly redundant.
Previously, the crc32 field in the data descriptor would return an error
if it did not match the central directory's entry. This check has
seemingly been unintentionally removed. If the central directory crc32
is invalid and a data descriptor is present, no error is returned.
This change reverts to the previous handling of data descriptors, before
CL 312310.

These new methods provide support for cases where performance is a
primary concern. For example, copying files from an existing zip to a
new zip without incurring the decompression and compression overhead.
Using an optimized, external compression method and writing the output
to a zip archive. And compressing file contents in parallel and then
sequentially writing the compressed bytes to a zip archive.

The switch case for fs.ModeDevice can only be reached for block devices
while character devices match fs.ModeDevice | fs.ModeCharDevice. This
would cause character devices to wrongly be reported as regular files.
This bug has existed since the switch was first introduced in CL 5624048.

The Modified field allows representation of extended timestamps, which provide more accuracy than the legacy MS-DOS timestamps.
The FileInfo method provides an implementation of the os.FileInfo interface for files inside archives.
With this change, we make FileInfo use the Modified field, if present, to return more detailed timestamps from its ModTime method.

In order to avoid a regression where the date of the ModTime method
changed behavior, simply preserve the old behavior of determining
the date based on the legacy fields.
This ensures that anyone relying on ModTime before Go1.10 will have
the exact same behavior as before.
New users should use FileHeader.Modified instead.
We keep the UTC coersion logic in SetModTime since some users
manually compute timezone offsets in order to have precise control
over the MS-DOS time field.

The NonUTF8 field provides users with a way to explictly tell the
ZIP writer to avoid setting the UTF-8 flag.
This is necessary because many readers:
1) (Still) do not support UTF-8
2) And use the local system encoding instead
Thus, even though character encodings other than CP-437 and UTF-8
are not officially supported by the ZIP specification, pragmatically
the world has permitted use of them.
When a non-standard encoding is used, it is the user's responsibility
to ensure that the target system is expecting the encoding used
(e.g., producing a ZIP file you know is used on a Chinese version of Windows).
We adjust the detectUTF8 function to account for Shift-JIS and EUC-KR
not being identical to ASCII for two characters.
We don't need an API for users to explicitly specify that they are encoding
with UTF-8 since all single byte characters are compatible with all other
common encodings (Windows-1256, Windows-1252, Windows-1251, Windows-1250,
IEC-8859, EUC-KR, KOI8-R, Latin-1, Shift-JIS, GB-2312, GBK) except for
the non-printable characters and the backslash character (all of which
are invalid characters in a path name anyways).

The ModifiedTime and ModifiedDate fields are not expressive enough
for many of the time extensions that have since been added to ZIP,
nor are they easy to access since they in a legacy MS-DOS format,
and must be set and retrieved via the SetModTime and ModTime methods.
Instead, we add new field Modified of time.Time type that contains
all of the previous information and more.
Support for extended timestamps have been attempted before, but the
change was reverted because it provided no ability for the user to
specify the timezone of the legacy MS-DOS fields.
Technically the old API did not either, but users were manually offsetting
the timestamp to achieve the same effect.
The Writer now writes the legacy timestamps according to the timezone
of the FileHeader.Modified field. When the Modified field is set via
the SetModTime method, it is in UTC, which preserves the old behavior.
The Reader attempts to determine the timezone if both the legacy
and extended timestamps are present since it can compute the delta
between the two values.
Since Modified is a superset of the information in ModifiedTime and ModifiedDate,
we mark ModifiedTime, ModifiedDate, ModTime, and SetModTime as deprecated.

This change reverts the following CLs:
CL/18274: handle mtime in NTFS/UNIX/ExtendedTS extra fields
CL/30811: only use Extended Timestamp on non-zero MS-DOS timestamps
We are reverting support for extended timestamps since the support was not
not complete. CL/18274 added full support for reading extended timestamp fields
and minimal support for writing them. CL/18274 is incomplete because it made
no changes to the FileHeader struct, so timezone information was lost when
reading and/or writing.
While CL/18274 was a step in the right direction, we should provide full
support for high precision timestamps in both the reader and writer.
This will probably require that we add a new field of type time.Time.
The complete fix is too involved to add in the time remaining for Go 1.8
and will be completed in Go 1.9.

We should preserve the fact that a roundtrip read on fields with the zero
value should remain the zero for those that are reasonable to stay that way.
If the zero value for a MS-DOS timestamp was used, then it is sensible for
that zero value to also be read back later.
