VFS mega cleanup commit (x/N)

1. Add new file "sys/kern/vfs_default.c" where default actions for
VOPs go. Implement proper defaults for ABORTOP, BWRITE, LEASE,
POLL, REVOKE and STRATEGY. Various stuff spread over the entire
tree belongs here.

2. Change VOP_BLKATOFF to a normal function in cd9660.

3. Kill VOP_BLKATOFF, VOP_TRUNCATE, VOP_VFREE, VOP_VALLOC. These
are private interface functions between UFS and the underlying
storage manager layer (FFS/LFS/MFS/EXT2FS). The functions now
live in struct ufsmount instead.

4. Remove a kludge of VOP_ functions in all filesystems, that did
nothing but obscure the simplicity and break the expandability.
If a filesystem doesn't implement VOP_FOO, it shouldn't have an
entry for it in its vnops table. The system will try to DTRT
if it is not implemented. There are still some cruft left, but
the bulk of it is done.

5. Fix another VCALL in vfs_cache.c (thanks Bruce!)

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
Mount_std mounts will not work until the getfsent
library routine is changed.

Eliminate unnecessary UFS1 integrity checks.

The UFS1 integrity checks added in FreeBSD 14 were too aggressive
for UFS1 filesystems created in FreeBSD 4 and 9 systems. This patch
removes those tests which can be done safely since they are not
relevant to the current implementation of UFS1.

Updates to UFS/FFS superblock integrity checks when reading a superblock.

Have to add a check that the computed cylinder group size does not
exceed the block size of the filesystem.

It is also necessary to validate additional parameters when a
superblock is going to be used in read-only mode if its supplementary
information is going to be read in to ensure that the size and
location of the supplementary information is valid. Also when a
warning is raised let it be accepted, but bound the flagged field
to the value checked by the warning.

No legitimate superblocks should fail as a result of these changes.
