Set MINFREE to 80, since that's a more reasonable value according to the literature than FFS' 90. Remove a bunch of other unused FFS cruft from config.h. Initialize lfs_bfree correctly vis-a-vis MIN_FREE_SEGS, so the filesystem doesn't over-represent the amount of free space it has. Initialize lfs_dmeta so the kernel can estimate starting from a reasonable value.
