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.

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.

Undo part of the ktrace/lwp changes. In particular:
...
* Remove the "lwp *" argument that was added to vget(). Turns out
that nothing actually used it!
* Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(),
and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted
above, didn't use it).
* Remove all of the "lwp *" arguments to internal functions that were added
just to appease the above.
