nandfs: Fixes.

- replace error numbers with proper macros
- get rid of some unused fields in fsdata and super block
- when erasing segment invalidate gc buffers that still point to it
- flag segments that are going to be erased (this flag should never hit
  storage - it is only so that cleaner does not try to clear one segment
  twice)
- place some asserts
- add veryfing FS revision at mount time
- rmdir without this operation left invalid data in inode
- file created right after deleted directory appeared as directory
- reduce inode size of removed directory to 0 (similar to ext2fs, msdosfs)
- check if inode has any links during lookup (similar to ufs)
- protect write entry points by very same lock used to protect segment
  construction - this servers as our own version of vfs_write_suspend
- ignore MNT_LAZY syncs - this is a hack used to ignore periodic syncs
  from mnt_syncer
