policycoreutils: setfiles: estimate percent progress

This patch started with work from John Reiser patch to estimate the
percent progress for restorecon/setfiles.

It has a lot of changes since then, to make it only happen on full
relabel, overwrite itself, shows 10ths of %, and does a lot better and
more useful job of estimation.  We get all of the inodes on all mounted
FS.  Since the number of inodes is not fixed and only an estimate I added
5% to the inode number, and forced the number to never go over 100.
