Recognize units at inode limits by setquota

This patch allows to specify suffixes at inode limits on setquota
command line and standard input. Decimal Units k, m, g, t are
implemented.  Numeric value without suffix is equivatent to single
inodes as before.  This is complementary functionality to `quota -s'.
