Re-arrange the interrupt handler to optimize the common case of

Smaller accesses have been observed to fail under some conditions.

something between a "move" and a "copy" operation. This is replaced
by M_MOVE_PKTHDR (which copies the pkthdr contents and "removes" it
from the source mbuf) and m_dup_pkthdr which copies the packet
header contents including any m_tag chain. This corrects numerous
problems whereby mbuf tags could be lost during packet manipulations.
These changes also introduce arguments to m_tag_copy and m_tag_copy_chain
to specify if the tag copy work should potentially block. This
introduces an incompatibility with openbsd which we may want to revisit.

The second bug applies only to NetBSD and OpenBSD and involves the curlen

Also cleanup the use of the OHIC_PAGE() macro on dataphysend and add a panic
if len goes negative (meaning we lost the physical page translation
representing the end of the buffer).
IMHO the dataphysend is still bokered since it might be misrepresented
