If the initial lookup shows that 'pending' is positive, then
self-heal will hold a lock and do a lookup again. This lookup
might show that 'pending' is zero everywhere. However, entry
self-heal used to consider this as a case of 'no sources' and
try to merge the directories. This patch checks for that case
and does not do the merge.

When an rmdir is being done, hold a lock on all names under it, so
that new entries cannot be created while the rmdir is in progress.
Without this lock, rmdir and create operations under the
victim directory race with each other leading to
inconsistencies among the subvolumes.

fixes the race where a subvolume might go down during the transaction

This patch helps to distribute load across an afr cluster
when you have clients with the same access patterns, such
as in benchmarking or map-reduce. By randomly offsetting
the initial read_child_rr, clients should distribute reads
over the afr nodes on average.
A better solution could be to randomly shuffle the children
instead of chosing a different initial offset. This should
average the reads better across the nodes, but I'm not
sure if there are any other consequences to doing this.

each of the subvolume
- This patch fixes bug #29.
- Using separate copies of dictionaries also eliminates a potential bug in a
setup consisting of afr with a posix and client, each having io-threads on
top as children. Since posix_xattrop after performing required operations
on the xattr array passed in dictionary, sets the result at the same key
and in the same dictionary passed as input argument,
there can be race conditions where in the results of the operation on
posix-child can be sent to the other child as input argument for xattrop,
which ofcourse is wrong.

Thanks to Krishna <krishna (at) gluster.com> for pointing this out.
When a unify self-heal of large directory (directory with lot of entries)
is done, the getdents_cbk used to fail because of new limit of buffer size
(128KB). Noticed that earlier it used to streach upto 4MB, hence the value
1024 worked fine. By reducing it to 512, noticed, we can fit in well within
128KB limit, and hence unify self-heal goes through.
