45a0c8fe56 fix memory allocation problems and collateral damage:
o create a separate tag for each object allocated with bus_dmamem_alloc so
  the tag's maxsize is setup appropriately; this reduces memory allocation
  for the queue descriptors from 16M to what it should be and also fixes
  memory allocation for public key operands
o release bus dma resources on detach so module usage doesn't leak
o remove public key op disable now that bus dma memory allocation is fixed
o collect attach error handling in one place

9d5abbddbf Correct typos, mostly s/ a / an / where appropriate. Some whitespace cleanup,
especially in troff files.

9967cafc49 Correct mbuf packet header propagation. Previously, packet headers
were sometimes propagated using M_COPY_PKTHDR which actually did
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.

Note that move/dup of packet headers does not handle target mbufs
that have a cluster bound to them.  We may want to support this;
for now we watch for it with an assert.

Finally, M_COPYFLAGS was updated to include M_FIRSTFRAG|M_LASTFRAG.

f544a52873 Module-ize the 'core' crypto stuff. This may still need to be compiled
into the kernel by default (if required), but other modules can now
depend() on this.

Fix inter-module dependancy.

this no longer happens for callbacks.

f96d19da13 Track openbsd changes that don't affect us yet (PK supoprt is
currently disabled):

o Don't use constants for the output parameter, use the iparam count as a
  pointer to the first result location.
o Fix bits vs bytes counting problems.
o Split out the hardware and software normalization versions of modexp.
o Enable hardware normalization for chips that support it.
o On reset, disable hardware normalization for 582x and make sure the
  chip is in little endian mode.
o Since sw normalization is now the only option, simplify normalization
  handling.

Also fix RNG harvesting: disabling PK support (for the moment) had disabled
the MCR2 interrupt; consider both KEY support and RNG support when deciding
whether or not to enable it.
