56350a991b Message types for VFS read, write & peek
All of these requests share the same message type as at least one server
manages those requests in the same handler, just by checking the actual
type of the request, and then acting upon it.

3de8d1cf6e VFS/PFS: remove notion of position in pipes
Because pipes have no file position. VFS maintained (file) offsets into a
buffer internal to PFS and stored them in vnodes for simplicity, mixing
the responsibilities of filp and vnode objects.

With this patch PFS ignores the position field in REQ_READ and REQ_WRITE
requests making VFS' job a lot simpler.

2bfeeed885 drop segment from safecopy invocations

	  to prepare for the segmentless world
	. still assign D to the SCP_SEG field in the message
	  to make previous kernels usable
