initial code repo

This patch creates initial code repo.

For ceph, luminous stable release will be used for base code,
and next changes and optimization for ceph will be added to it.

For opensds, currently any changes can be upstreamed into original
opensds repo (https://github.com/opensds/opensds), and so stor4nfv
will directly clone opensds code to deploy stor4nfv environment.
And the scripts for deployment based on ceph and opensds will be
put into 'ci' directory.

+    librados: fix async aio completion wakeup
+
+    For aio flush, we register a wait on the most recent write.  The write
+    completion code, however, was *only* waking the waiter if they were waiting
+    on that write, without regard to previous writes (completed or not).
+    For example, we might have 6 and 7 outstanding and wait on 7.  If they
+    finish in order all is well, but if 7 finishes first we do the flush
+    completion early.  Similarly, if we
+
+     - start 6
+     - start 7
+     - finish 7
+     - flush; wait on 7
+     - finish 6
+
+    we can hang forever.
+
+    Fix by doing any completions that are prior to the oldest pending write in
+    the aio write completion handler.

+    librados: fix locking for AioCompletionImpl refcounting
+
+    Add an already-locked helper so that C_Aio{Safe,Complete} can
+    increment the reference count when their caller holds the
+    lock. C_AioCompleteAndSafe's caller is not holding the lock, so call
+    regular get() to ensure no racing updates can occur.
+
+    This eliminates all direct manipulations of AioCompletionImpl->ref,
+    and makes the necessary locking clear.
+
+    The only place C_AioCompleteAndSafe is used is in handling
+    aio_flush_async(). This could cause a missing completion.

+    osd: fix race when queuing recovery ops
+
+    Previously we would sample how many ops to start under the lock, drop it,
+    and start that many.  This is racy because multiple threads can jump in
+    and we start too many ops.  Instead, claim as many slots as we can and
+    release them back later if we do not end up using them.
+
+    Take care to re-wake the work-queue since we are releasing more resources
+    for wq use.

+    osd: tolerate racing threads starting recovery ops
+
+    We sample the (max - active) recovery ops to know how many to start, but
+    do not hold the lock over the full duration, such that it is possible to
+    start too many ops.  This isn't problematic except that our condition
+    checks for being == max but not beyond it, and we will continue to start
+    recovery ops when we shouldn't.  Fix this by adjusting the conditional
+    to be <=.

+
+    This would of course become a problem when trying to obtain the observer

+    empty.  Fix discard_requeued_up_to() to avoid creating an entry unless we
+    know it is already present.
+
+    This bug leads to an incorrect reconnect attempt when
+
+     - we accept a pipe (lossless peer)
+     - they send some stuff, maybe
+     - fault
+     - we initiate reconnect, even tho we have nothing queued
+
+    In particular, we shouldn't reconnect because we aren't checking for
+    resets, and the fact that our out_seq is 0 while the peer's might be
+    something else entirely will trigger asserts later.
+
