*  Fixed 1299:aborted request tripped LASSERT(!req->rq_receiving_reply)

*  Fixed ll_readpage() to read file's preferred block size to take
   advantage of obd_brw_async()

*  made obdstat names consistent ('echo' and 'filter')

*  fixed what looked like a type in portals/configure.in and hacked
   portals/knals/qswnal/Makefile.am to -I the qsw headers from the
   configured dir.

*  Put magic into portals network interface handles and put type info into
   portals ME and MD handles, and portals' own internal EQ handles.  Misuse
   now makes things fail/crash more promptly.
