This patch introduces CtxRestoreFilesystemFDMap in vfs to replace the CtxRestoreServerFDMap defined in gofer, which is a preparation for adding the checkpoint/restore support in EROFS. It allows the configureRestore() in boot/vfs.go to be agnostic to the filesystems that will be used in the sentry when configuring restore. Signed-off-by: Tiwei Bie <tiwei.btw@antgroup.com>
