Standardize the style for compiler based printf format verification.
Standardized the location of __printf too.
Done via script and a little typing.
$ grep -rPl --include=*.[ch] -w "__attribute__" * | \
grep -vP "^(tools|scripts|include/linux/compiler-gcc.h)" | \
xargs perl -n -i -e 'local $/; while (<>) { s/\b__attribute__\s*\(\s*\(\s*format\s*\(\s*printf\s*,\s*(.+)\s*,\s*(.+)\s*\)\s*\)\s*\)/__printf($1, $2)/g ; print; }'

This introduces a new per-superblock mutex in UFS to replace
the big kernel lock. I have been careful to avoid nested
calls to lock_ufs and to get the lock order right with
respect to other mutexes, in particular lock_super.
I did not make any attempt to prove that the big kernel
lock is not needed in a particular place in the code,
which is very possible.
The mutex has a significant performance impact, so it is only
used on SMP or PREEMPT configurations.
As Nick Piggin noticed, any allocation inside of the lock
may end up deadlocking when we get to ufs_getfrag_block
in the reclaim task, so we now use GFP_NOFS.

This gives the filesystem more information about the writeback that
is happening. Trond requested this for the NFS unstable write handling,
and other filesystems might benefit from this too by beeing able to
distinguish between the different callers in more detail.

ufs2 fast symlinks can be twice as long as ufs ones, however the code
was using the ufs size in various places. Fix that so ufs2 symlinks over
60 characters aren't truncated.
Note that we copy the entire area instead of using the maxsymlinklen field
from the superblock. This way we will be more robust against corruption (of
the superblock).
While we are at it, use memcpy instead of open-coding it with for loops.

Stop the UFS filesystem from using iget() and read_inode(). Replace
ufs_read_inode() with ufs_iget(), and call that instead of iget(). ufs_iget()
then uses iget_locked() directly and returns a proper error code instead of an
inode in the event of an error.
ufs_fill_super() returns any error incurred when getting the root inode
instead of EINVAL.

Move prototypes and in-core structures to fs/ufs/ similar to what most
other filesystems already do.
I made little modifications: move also ufs debug macros and
mount options constants into fs/ufs/ufs.h, this stuff
also private for ufs.
