you added flushing of trn, xtc and ern before the checkpointing
functionality had been added. The additional flush can add quite a bit
of unnecessary time especially with parallel file systems and/or MPI-IO. Am
I right that with checkpointing it is not necessary anymore? The
checkpointing is flushing the file before writing the checkpoint.
Also gmx_fio_check_file_position is flushing the file before checking
whether the file is too large for gmx_off_t.
