merge gmnal code in b_llp2 to HEAD

*  Fixed obdecho persistent object size at 1 MByte.

*  Changed test_brw data verification tests to work on a fixed 4k block
   rather than on page size to allow different page sized servers and
   clients.

   forwarding interface from a single struct iovec for the message header +
   payload, to passing the message header by pointer, and the message body
   by ptl_kiov_t (== page,offset,size).  This restores portals router
   performance by allowing it to use socknal zero copy again.

*  Applied the socknal connection load balancing fix from Bug 2817

other places were still fixed).  NB: a lock on [x,y] protects a KMS of
up to y+1 bytes.

move defination IOC_MDC_GETSTRIPE and declaration op_create_file() to lustre_user.h cause it is needed for user-space apps.

add a funcation int get_file_stripe(char *path, struct lov_user_md *lum) in liblustreapi.c, which is used by user apps want to get Lustre files' stripe info

if mount.lustre is not installed, don't oops but print a message
suggesting it be checked.

land b_size on HEAD for 1.2
