	mbuf/userland/mbuf_impl: uipc_mbuf.c uipc_mbuf2.c
	mbuf/userland/mbuf_impl/sys: mbuf.h

Log Message:
Add m_datarange and m_datarange_rw functions, which correspond to
mptr_pullup and mptr_rw macros, but without the sizeof magic - they accept
an explicit "len" argument.

Rename some flags to the m_pulldown0 internal function and add new flags
to request blocking allocation, alignment and leading space in a newly
allocated mbuf. (The intent is to duplicate the functionality of m_copyup.)
The new functions accept those flags, too.

Change the semantics of mptr a bit - now it assumes that all the data are
in the first mbuf, even in the case ofa nonzero offset.

Revert to upstream version 1.110 of uipc_mbuf.c, this is what corresponds
to my kernel snapshot.

	mbuf/userland/mbuf_impl: uipc_mbuf.c uipc_mbuf2.c
	mbuf/userland/mbuf_impl/sys: mbuf.h

Log Message:
Add a m_contig member to struct mbuf, which describes how much data is
guaranteed to be contiguous. Add macros to manipulate m_data and m_len,
which take care of updating m_contig. (If m_data and m_len are manipulated
directly, nothing bad happens, only it may happen that a contiguous region 
is created when not necessary.)

Adapt the mbuf routines to those macros.

Adapt m_pulldown0 (the backend for mptr* and m_pulldown) to respect
m_contig.
