bc69d62669 Linux: Add fchmodat fallback when flags is nonzero 
The check for determining whether to use the fallback code has been
moved into an inline function as per Andrew's comments in #17954.

26db31f6f6 Add fchmodat2 to the Linux syscall list 
This syscall was added to simplify the the libc implementations of
fchmodat, as the original syscall does not take a `flags` argument.

Another syscall, `map_shadow_stack`, was also added for x86_64.

bd46410419 Revert "Merge pull request #18410 from dweiller/by-length-slice-bug" 
This reverts commit d9d840a33a, reversing
changes made to a04d433094.

This is not an adequate implementation of the missing safety check, as
evidenced by the changes to std.json that are reverted in this commit.

Reopens #18382
Closes #18510

7d3a31872e tar: improve diagnostic reporting 
Using Python testtar file (mentioned in #14310) to test diagnostic
reporting.
Added computing checksum by using both unsigned and signed header bytes
values.
Added skipping gnu exteneded sparse headers while reporting unsupported
header in diagnostic.

Note on testing:

wget https://github.com/python/cpython/raw/3.11/Lib/test/testtar.tar -O
/tmp/testtar.tar

```
test "Python testtar.tar file" {
    const file_name = "testtar.tar";

    var file = try std.fs.cwd().openFile("/tmp/" ++ file_name, .{});
    defer file.close();

    var diag = Options.Diagnostics{ .allocator = std.testing.allocator };
    defer diag.deinit();

    var iter = iterator(file.reader(), &diag);
    while (try iter.next()) |f| {
        std.debug.print("supported: {} {s} {d}\n", .{ f.kind, f.name, f.size });
        try f.skip();
    }
    for (diag.errors.items) |e| {
        switch (e) {
            .unsupported_file_type => |u| {
                std.debug.print("unsupported: {} {s}\n", .{ u.file_type, u.file_name });
            },
            else => unreachable,
        }
    }
}
```

7923a53996 tar: rename reader to iterator 
Itarator has `next` function, iterates over tar files. When using from
outside of module with `tar.` prefix makes more sense.

var iter = tar.iterator(reader, null);
while (try iter.next()) |file| {
...
}

e1424b84b8 tar: add parsing size in gnu extended format 
Reference:
https://www.gnu.org/software/tar/manual/html_node/Extensions.html#Extensions

If the leading byte is 0x80 (128), the non-leading bytes of the field
are concatenated in big-endian order, with the result being a positive
number expressed in binary form.

45ec851733 zig build: handle stderr more elegantly 
* Specifically recognize stderr as a different concept than an error
  message in Step results.
* Display it differently when only stderr occurs but the build proceeds
  successfully.
