75571afd93 Stick ffs_ in front of the following macros: 
fragstoblks()
   blkstofrags()
   fragnum()
   blknum()

to finish the job of distinguishing them from the lfs versions, which
Christos renamed the other day.

I believe this is the last of the overtly ambiguous exported symbols
from ffs... or at least, the last of the ones that conflicted with lfs.
ffs still pollutes the C namespace very broadly (as does ufs) and this
needs quite a bit more cleanup.

XXX: boo on macros with lowercase names. But I'm not tackling that just yet.

e1610ba4cb Stick ffs_, ext2_, chfs_, filecore_, cd9660_, or mfs_ in front of 
the following symbols so as to disambiguate fully. (Christos already
did the lfs ones.)

   lblkno
   lblktosize
   lfragtosize
   numfrags
   blkroundup
   fragroundup

2737439da3 fsbtodb() -> FFS_FSBTODB(), EXT2_FSBTODB(), or MFS_FSBTODB() 
dbtofsb() -> FFS_DBTOFSB() or EXT2_DBTOFSB()

(Christos already did the lfs ones a few days back)

dcd34a91c5 Stuff UFS_ in front of a few of ufs's symbols to reduce namespace 
pollution. Specifically:
   ROOTINO -> UFS_ROOTINO
   WINO -> UFS_WINO
   NXADDR -> UFS_NXADDR
   NDADDR -> UFS_NDADDR
   NIADDR -> UFS_NIADDR
   MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN
   MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency)

Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have
the same values in ext2fs and ffs.

No functional change intended.

error and modify all callers to not brelse() on error.

6c899f7536 For update mounts the root vnode is already in use and we must not 
free it. Since the mount persists even when the update fails,
this is not a problem either.

5eee906941 mount(2) doesn't remove vnodes from the freelist in the error path, 
so that they get reused with a invalid pointer to a mount structure.

As a workaround, free the vnodes used to create the in-filesystem journal
immediately.

No longer limits physical sector sizes to 512 bytes.

32992733fa Allow tunefs to clear any type of WAPBL log, not only in-filesystem 
ones. Discussed in

dfd7714b8f Split ffs_blkalloc into a frontend that does inode based consistency 
checks and a backend that just asserts them. Use the backend in
ffs_wapbl_abort_sync_metadata instead of faking an inode.
