a3d987fa73 Fix snapshot monitoring library to not cancel monitoring invalid snapshot. 
snapshot DSO unregistered itself when snapshot changed state to invalid.

This can cause a race (and several timeouts), when for example another snapshot
is added and in the middle of operation (suspend/resume) the monitoring thread
unregister itself.

Fix it by keeping the snapshot monitored after invalidation - just reset
threshold to not really print any messages to syslog.

efde37880b Fix dmeventd regression where mirror and snapshot monitoring libraries 
failed to link against liblvm2cmd.

Dmeventd DSOs *require* lvm2cmd to be linked in.

For the future:
1) AC_SUBST does not create Makefile variables, only @foo@-style substitutions
2) When using `test', whitespace around `=' is essential:
    test a=b is true, as is test a=a

062886df64 avoid link failure when configuring without --enable-cmdlib 
* configure.in (LVM2CMD_LIB): Define if --enable-cmdlib.
* dmeventd/mirror/Makefile.in (CLDFLAGS): Use $(LVM2CMD_LIB) rather
than hard-coding -llvm2cmd.
* dmeventd/snapshot/Makefile.in (CLDFLAGS): Likewise.

ce3a68d817 Make clvmd-cman use a hash rather than an array for node updown info. 
This will allow it to cope with very large nodeids such as those
generated by clusters using cman_tool join -X

9154a74400 . remove_lock_wait.diff remove the definition of "struct lock_wait", 
which is not used since the switch away from async version saLck
. num_nodes should equal to member_list_entries, i.e.
joined_list_entires is 0 when a node leaves the group.

Thanks to Xinwei Hu for the patch.

1399b84b32 The attached patch is a try to make clvmd work correctly on openais stack. 
It does 2 things.

1. The cpg_deliver_callback make a compare between target_nodeid and our_nodeid.
It turns out openais set target_nodeid to 0 sometimes. for broadcasting ? I change the behavior so that lvm will process_remote also on target_nodeid == 0

2. The joined_list passed to cpg_confchg_callback doesn't include the already exist nodes in the group, which leads to an incomplete node_hash. I simply add all other nodes in member_list to node_hash also.

Thanks to Xinwei Hu for this patch.

e7bdd69af0 If lvm.conf was touched, clvmd attempted to update the toolcontext 
but only did half of the job. It now shares the do_refresh_cache()
function that vgscan invokes.
