Migrating these functions to allow them being shared between moby, docker/cli, and containerd, and to allow using them without importing all of sys / system, which (in containerd) also depends on hcsshim and more. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>

// Package sequential provides a set of functions for managing sequential
|
|
// files on Windows.
|
|
//
|
|
// The origin of these functions are the golang OS and windows packages,
|
|
// slightly modified to only cope with files, not directories due to the
|
|
// specific use case.
|
|
//
|
|
// The alteration is to allow a file on Windows to be opened with
|
|
// FILE_FLAG_SEQUENTIAL_SCAN (particular for docker load), to avoid eating
|
|
// the standby list, particularly when accessing large files such as layer.tar.
|
|
//
|
|
// For non-Windows platforms, the package provides wrappers for the equivalents
|
|
// in the os packages. They are passthrough on Unix platforms, and only relevant
|
|
// on Windows.
