* Fix buffer ordering when it has dependencies.
* Alleviate memory problems.
* Deal with some recursive vnode locks (sigh).
* Fix other bugs.

Remove a few redundant splbio() calls (ACQUIRE_LOCK already does splbio())

Use splbio() in getdirtybuf() to prevent bad things from happening due
to queue race conditions. Don't use B_VFLUSH as it's not appropriate for
this case.

Be more careful to block bio interrupts for some data structures. There
were at least a few missed cases where vp->v_{clean,dirty}blkhd were
unprotected since the softdep/trickle sync merge.

Set the limit at which flushing is sped up to prevent excessive memory
usage a little lower.

Add the parts of the softdep code that fall under Kirk's more GPL-like
copyright here. To be optionally included in the kernel using the
prefix and cinclude mechanism.
