The lack of checking bmp->db_max_freebud in extBalloc() can lead to
shift out of bounds, so this patch prevents undefined behavior, because
bmp->db_max_freebud == -1 only if there is no free space.

Since the JFS code was first added to Linux, there has been code hidden
in ifdefs for some potential future features such as defragmentation
and supporting block sizes other than 4KB. There has been no ongoing
development on JFS for many years, so it's past time to remove this dead
code from the source.

Use a more current logging style.
Add __printf format and argument verification.
Remove embedded function names from formats.
Add %pf, __builtin_return_address(0) to jfs_error.
Add newlines to formats for kernel style consistency.
(One format already had an erroneous newline)
Coalesce formats and align arguments.
Object size reduced ~1KiB.

Get rid of the alloc_space, free_space, reserve_space, claim_space and
release_rsv dquot operations - they are always called from the filesystem
and if a filesystem really needs their own (which none currently does)
it can just call into it's own routine directly.
Move shared logic into the common __dquot_alloc_space,
dquot_claim_space_nodirty and __dquot_free_space low-level methods,
and rationalize the wrappers around it to move as much as possible
code into the common block for CONFIG_QUOTA vs not. Also rename
all these helpers to be named dquot_* instead of vfs_dq_*.

Commit fec1878fe952b994125a3be7c94b1322db586f3b caused a regression in
which contiguous blocks being allocated to the end of an extent were
getting a new extent created. This typically results in files entirely
made up of 1-block extents even though the blocks are contiguous on
disk.
Apparently grub doesn't handle a jfs file being fragmented into too many
extents, since it refuses to boot a kernel from jfs that was created by
the 2.6.30 kernel.

xtLookupList() was a more generalized version of xtLookup() with a
nastier interface. Its only caller, extHint(), is actually better
suited to using xtLookup() than xtLookupList(). This also lets us
remove the definition of lxd_t, an obnoxious packed structure that was
only used in-memory.

This eliminates the i_blksize field from struct inode. Filesystems that want
to provide a per-inode st_blksize can do so by providing their own getattr
routine instead of using the generic_fillattr() function.
Note that some filesystems were providing pretty much random (and incorrect)
values for i_blksize.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
