5c09d20130 Declare fs_old_flags and fs_flags as unsigned. 
This fixes a bug introduced in revision 1.120 of ffs_vfsops dated 2003/09/13
which results in fs_flags having a value of 0x7fffff00 when a superblock
is updated to use the new layout.
Discussed in http://mail-index.netbsd.org/tech-kern/2003/09/28/0003.html

61d5d4362b fix a bug of lfs. 
genfs_getpages() can read in more blocks than it should due to faked filesize
of lfs_gop_size().  it's a security problem and it makes gcc3 "internal error"

to fix this,
- in genfs_getpages(), always calculate diskeof and memeof separately
  so that filesystems (in this case, lfs) can use different strategies
  for them.
- introduce GOP_SIZE_MEM flag and use it to request in-core filesize.
  (it was an intention of GOP_SIZE_READ,
  but after the above change _READ is not a straightforward name)

after this, no one uses GOP_SIZE_{READ,WRITE} anymore but leave them for now.

69615345e2 Fix a recently introduced bug which prevents csum totals being copied 
when an old ffs filesytem is first mounted (as a result, df reports disk
full on old ffs filesystem or mfs created by old binary).  Problem first

to avoid compat problems with old ffsv1 by reuse of the old FS_SWAPPED
value for FS_FLAGS_UPDATED, and use of new, larger fields:
- Don't use FS_FLAGS_UPDATED to see if we need to update new fields from
  old fields in ffsv1 case.
- when writing back the superblock, copy back the flags to the old location
  if only old flags are set (FS_FLAGS_UPDATED won't be set in this case)
  in ffsv1 case.

5638922967 Stop panic if 'mknod xxx b 0 0' done on a full filesystem. 
panics in ffs_full_fsync because v_specmountpoint requires that the NULL
v_specinfo be followed.
Tidy up in the same order in all error paths so compiler can merge the
code sequences.
