- Use TAILQ_* macros extensively instead of internal names
- use b_xflags instead of the NOLIST magic number hack in the next pointer
- clean bufs are inserted at the tail rather than the head.
- redo dirty buffer insert so that metadata (negative lbn) goes to the
tail directly rather than at the HEAD. This makes a difference when
inserting dirty data blocks in lbn sorted order since data block
insertion will not have to bypass all the metadata cruft. data is
lbn sorted since it makes sense for clustering and writeback ordering,
while metadata sorting doesn't help much since the lbn's are
meaningless when walking the list for writebacks.
Small systems will not notice much (if any) benefit from this, but really
busy systems with large dirty block lists should get a lot more.
I've tested this with softdep, and it doesn't seem to mind the change of
queueing of metadata.

Add a new flags field (we get this for free because of struct packing)
for cleaner management of tailq membership.
We had two spare b_flags slots, but they are a precious resource and may
be needed for other things that are related to other b_flags bits. The two
new flags are convenient to use in a seperate location.

While here, have vfs_msync() only call vm_object_page_clean() with
OBJPC_SYNC if called with MNT_WAIT flags. vfs_msync() is called at unmount
time (with MNT_WAIT) and from the syncer process (formerly update).
This should make dirty mmap writebacks a little less nasty.

Cryptbreakers Workbench. While arguably a rather weak encryption,

Silently agreed by: core
packages from a single port. LOOP_VAR is the name of the variable
and LOOP_OPTIONS is a space-separated list of values it should
take. When these are set, the target "package-loop" will go
through a clean and package loop for all the options. The
"package-loop" target is defined as "package" when LOOP_VAR is not
defined, so if you are in the business for building packages, you
should use "package-loop" all the time. (This target is added to
bsd.port.subdir.mk too.)
Also, the "describe" target prints out multiple lines so that all
options will go into the INDEX. (In other words, if you define
these variables, INDEX is going to look real silly if you don't
put ${${LOOP_VAR}} in PKGNAME.)

doesn't make any sense.
