added prototypes for every function and
put (void *) as the args to the vop array definitions.

can now compile with:
CWARNFLAGS?=    -W -Wreturn-type -Wcomment -Wredundant-decls -Wimplicit \
                -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes \
                -Winline -Wstrict-prototypes
and only get errors for files external to this module:
namely
./vnode_if.h
../../sys/vnode.h
../../sys/buf.h
../../miscfs/specfs/specdev.h
