copy-file-range: work around Linux kernel bug
This workaround is adapted from Coreutils.
* lib/copy-file-range.c [__linux__ && HAVE_COPY_FILE_RANGE]:
Include <sys/utsname.h>.
(copy_file_range): Use a stub to replace the copy_file_range of
Linux kernel versions 4.5 through 5.2.
* lib/unistd.in.h (copy_file_range):
* m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS):
* modules/copy-file-range (configure.ac):
* modules/unistd (unistd.h):
Support replacement of copy_file_range.
* m4/copy-file-range.m4 (gl_FUNC_COPY_FILE_RANGE):
Define HAVE_COPY_FILE_RANGE if the system has copy_file_range,
and on Linux check whether the system’s is known to work.
