Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD. - Not enabled by default. Needs kernel option FFS_SNAPSHOT. - Change parameters of ffs_blkfree. - Let the copy-on-write functions return an error so spec_strategy may fail if the copy-on-write fails. - Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock. - Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer. - Add a function ffs_checkfreefile needed for snapshot creation. - Add special handling of snapshot files: Snapshots may not be opened for writing and the attributes are read-only. Use the mtime as the time this snapshot was taken. Deny mtime updates for snapshot files. - Add function transferlockers to transfer any waiting processes from one lock to another. - Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through a vnode. - Add snapshot support to ls, fsck_ffs and dump. Welcome to 2.0F. Approved by: Jason R. Thorpe <thorpej@netbsd.org>

Cleanup how file system configuration information is declared, grouping related information together, with the file system code itself. This is just low-hanging fruit -- more to come.

Add support for the Apple UFS variation on ffs This is the bulk of PR #17345 The general approach is to use a run time deteriminable value for DIRBLKSIZ. Additional allowances are included for using MAXSYMLINKLEN with FS_42INODEFMT and a shift in the cylinder group cluster summary count array. Support is added for managing the Apple UFS volume label.
