Separate the struct bio related stuff out of <sys/buf.h> into

<sys/bio.h>. <sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall not be made a nested include according to bdes teachings on the subject of nested includes. Diskdrivers and similar stuff below specfs::strategy() should no longer need to include <sys/buf.> unless they need caching of data. Still a few bogus uses of struct buf to track down.

- *			B_ASYNC is set, but some subsystems, such as NFS, like 
- *			to know what is best for the caller so they can
- *			optimize the I/O.
- *
- *	B_PAGING	Indicates that bp is being used by the paging system or
- *			some paging system and that the bp is not linked into
- *			the b_vp's clean/dirty linked lists or ref counts.
- *			Buffer vp reassignments are illegal in this case.
- *
- *	B_CACHE		This may only be set if the buffer is entirely valid.
- *			The situation where B_DELWRI is set and B_CACHE is
- *			clear MUST be committed to disk by getblk() so 
- *			B_DELWRI can also be cleared.  See the comments for
- *			getblk() in kern/vfs_bio.c.  If B_CACHE is clear,
- *			the caller is expected to clear BIO_ERROR and B_INVAL,
- *			set BIO_READ, and initiate an I/O.
- *
- *			The 'entire buffer' is defined to be the range from
- *			0 through b_bcount.
- *
- *	B_MALLOC	Request that the buffer be allocated from the malloc
- *			pool, DEV_BSIZE aligned instead of PAGE_SIZE aligned.
- *
- *	B_CLUSTEROK	This flag is typically set for B_DELWRI buffers
- *			by filesystems that allow clustering when the buffer
- *			is fully dirty and indicates that it may be clustered
- *			with other adjacent dirty buffers.  Note the clustering
- *			may not be used with the stage 1 data write under NFS
- *			but may be used for the commit rpc portion.
- *
- *	B_VMIO		Indicates that the buffer is tied into an VM object.
- *			The buffer's data is always PAGE_SIZE aligned even
- *			if b_bufsize and b_bcount are not.  ( b_bufsize is 
- *			always at least DEV_BSIZE aligned, though ).
