xfs: support preallocating and copying content into temporary files
Create the routines we need to preallocate space in a temporary ondisk
file and then copy the contents of an xfile into the tempfile. The
upcoming rtsummary repair feature will construct the contents of a
realtime summary file in memory, after which it will want to copy all
that into the ondisk temporary file before atomically committing the new
rtsummary contents.
