This implements chown support on Windows. Built-in accounts as well as accounts included in the SAM database of the container are supported. NOTE: IDPair is now named Identity and IDMappings is now named IdentityMapping. The following are valid examples: ADD --chown=Guest . <some directory> COPY --chown=Administrator . <some directory> COPY --chown=Guests . <some directory> COPY --chown=ContainerUser . <some directory> On Windows an owner is only granted the permission to read the security descriptor and read/write the discretionary access control list. This fix also grants read/write and execute permissions to the owner. Signed-off-by: Salahuddin Khan <salah@docker.com>
