[sheepdog] [PATCH v4 0/2] Handle pending block/notify event during reconnect

[Kai Zhang]

v4:
- move SD_RES_CLUSTER_ERROR from sheepdog_proto.h to internal_proto.h and
  update error code to 0x91 which is larger than 0x80
- add_event() in zookeeper and send_message() in corosync now return
  SD_RES_SUCCESS on success and SD_RES_CLUSTER_ERROR on failure.
- call sd_notify_handler to finish pending notify requests during reconnect,
  but not requeue it.

v3:
- first two patches have been applied
- update comment in group.c
- block/unblock/notify return SD_RES_XXX in all cluster drivers, other than 0
  or -1
- print debug message when neccessary

v2:
- update commit log of patch 3/4

This series is to enhance the implementation of sd_reconnect_handler()
by handling pending block/notify event during reconnect.
