Handle cases where dma function pointers may be NULL, and where
the max_iosize can't be derived from a DMA data structure. For
the latter, revert to the prior behaviour of using DFLTPHYS for
the max i/o size when there is no other data.

aligned on an 8 byte boundary. Prior to rev 1.36 this wasn't a problem
because mbuf clusters tend be naturally aligned. The switch to using
split buffers with the first buffer being the embedded data area of the
mbuf has broken this assumption, at least on i386, causing a complete
failure of RX functionality. Fix this for now by using a full cluster for
the first RX buffer. A more sophisticated approach could be done with the
old buffer scheme to realign the m_data pointer with m_adj(), but I'm also
not clear on performance benefits of this old scheme or the performance
implications of adding an m_adj() call to every allocation.

various form of diagrams can be build.
The sysctl is called debug.witness.graphs and it is read-only; in order
to get the list of relations, a simple:
#sysctl debug.witness.graphs
will do the trick.
This approach has been choosen in order to support easilly things like
the DOT format and such. Soon, an auto-explicative awk script, which
filters simple informations returned by the sysctl and converts them into
a real DOT script, will be committed to the repository between examples.

ALT_BREAK_TO_DEBUGGER. In addition to "Enter ~ ctrl-B" (to enter the
debugger), there is now "Enter ~ ctrl-P" (force panic) and
"Enter ~ ctrl-R" (request clean reboot, ala ctrl-alt-del on syscons).
We've used variations of this at work. The force panic sequence is
best used with KDB_UNATTENDED for when you just want it to dump and
get on with it.
The reboot request is a safer way of getting into single user than
a power cycle. eg: you've hosed the ability to log in (pam, rtld, etc).
It gives init the reboot signal, which causes an orderly reboot.
I've taken my best guess at what the !x86 and non-sio code changes
should be.
This also makes sio release its spinlock before calling KDB/DDB.
