logrotate 3.7.9: Allow rotate log across filesystems
The logrotate can't save the log across the different filesystems since
it used the "rename(const char *oldpath, const char *newpath)" to save
the file, fix it to act as the "mv" command(first rename, if failed,
read and write) to allow save the log across the different filesystems.
* config.c: Remove the check for different filesystems
* logrotate.c: Act as the "mv" command when rotate log
* logrotate.8: Update the mannual
* logrotate.8: Fix a bug in the mannual(\f should be \fR)
