Log Message:
Some rump kernel components for interfacing with the environment need
to access both NetBSD kernel facilities and facilities provided by the
environment.
Where the environment's headers can be #included without namespace
conflict (which can be done - with care - for some Xen mini-os
headers), it is convenient to simply allow the rump kernel code to
call directly into the environment.
This also requires not mangling the symbol names.
So provide a variable RUMP_SYM_NORENAME which can be set by a component
namefile to a series of symbols or symbol prefixes (in makefile-quoted
awk regexp syntax). For example, in the rumpuser-xen xenbus driver:
RUMP_SYM_NORENAME=xenbus_|HYPERVISOR_|wake$$|block$$|schedule$$|force_evtchn
