b1bf5f1738 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

d474909a58 . 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.

746e7dc42e 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.

ec074fcf64 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.

f28fd56f76 libdevmapper, dmeventd: be paranoid about detecting write failure 
* dmeventd/dmeventd.c (_set_oom_adj): When writing to /proc/self/oom_adj,
detect failure even if it's hidden behind ferror.  [Using dm_fclose's
extra ferror test here is probably not needed, since the amount written
is nowhere near BUFSIZ, but use it regardless, for consistency. ]
* lib/fs/libdevmapper.c (do_suspend): Detect fclose failure when
writing to suspend.

* lib/config/config.c (_line_append): Likewise.
