Before this commit, the save-entropy script rotates entropy files like logs. This involves creating a new file that holds the entropy and renaming of all existing entropy files. However, the entropy data do not really need to be kept in a particular order, and replacing the oldest file is sufficient. This commit replaces the rotation with a scan in the [1..entropy_save_num] space that finds the first empty slot, or the slot of the oldest file, and writes entropy into that slot. This also fixes an issue that prevents save-entropy from saving any entropy when there is one non-regular file in any slot as a side effect. Based on an earlier patch from peterj@.

FreeBSD
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
