test-container: Use xcopy_file_range for cross-device copy [BZ #23597]
copy_file_range can't be used to copy a file from glibc source directory to glibc build directory since they may be on different filesystems. This patch adds xcopy_file_range for cross-device copy. Reviewed-by: Carlos O'Donell <carlos@redhat.com> [BZ #23597] * support/Makefile (libsupport-routines): Add support_copy_file_range and xcopy_file_range. * support/support.h: Include <sys/types.h>. (support_copy_file_range): New prototype. * support/support_copy_file_range.c: New file. Copied and modified from io/copy_file_range-compat.c. * support/test-container.c (copy_one_file): Call xcopy_file_rang instead of copy_file_range. * support/xcopy_file_range.c: New file. * support/xunistd.h (xcopy_file_range): New prototype.
