Rename pg_rewind's copy_file_range() to avoid conflict with new linux syscall.
Upcoming versions of glibc will contain copy_file_range(2), a wrapper
around a new linux syscall for in-kernel copying of data ranges. This
conflicts with pg_rewinds function of the same name.
Therefore rename pg_rewinds version. As our version isn't a generic
copying facility we decided to choose a rewind specific function name.
Per buildfarm animal caiman and subsequent discussion with Tom Lane.
