If cm_SyncOp is called with the buffer locked, it must be returned
locked even on error.

When Freelance mode is not in use the cache manager must load the root.afs
volume of the default cell in order to be able to start. Unfortunately,
if the first vlserver fails the request to obtain the volume information
will timeout and no retries will be performed. This patch performs up
to 10 retries in the initialization code in order to enable the vlservers
to be marked down so that failover can occur.

In h_FindClient_r it was possible for the wrong client to be returned

"the non AFS_GLOBAL_RXLOCK_KERNEL version of
rxi_ReceiveAckPacket() wasnt counting 'hard' acks and not opening the
congestion window. using rx_Readv() directs the incoming packets into
the target iov, and sends a hard ack (skipping soft acks). "

A deadlock was detected when performing "fs flushall" if the file
server reports VNOVNODE. The scp->createBufferLock is already
held by the current thread and there is no mechanism to propagate
the knowledge. Therefore, an alternate mechanism for clearing the
cache must be developed. A new function cm_RecycleSCache(scp,flags)
has been extracted from cm_GetNewSCache(). This function performs
the task of recycling an cm_scache_t object. When called from
cm_GetNewSCache() with no flags the expectation is that there are
no associated buffers that are queued to be read or written. When
called from cm_Analyze() with the CM_SCACHE_RECYCLEFLAG_DESTROY_BUFFERS
flag, any queued buffers will be de-queued and marked as if the operations
were performed so the data can be discarded.
This patch also addresses the following issues:
* CM_ERROR codes were logged as "unknown" by cm_Analyze.
* In response to VNOVNODE, the parent is only discarded if the current
cm_scache_t is not a directory.
* In the Ioctl FlushFile and FlushVolume functions, there were no
checks to protect against flushing the Freelance SCache entries.
* In FlushFile, the wrong cm_scache_t object was being released.
* In cm_GetNewSCache, do not allow Freelance SCache entries to be
recycled. Choose a new entry if cm_RecycleSCache fails.

while investigating the cause of the delayed write errors it was observed
that all of the sleep queues are LIFO. This has the side effect of
encouraging starvation. Changing the queues to FIFOs revealed a serious
problem affecting the use of all queues which use both head and tail
pointers. The removal function osi_QRemove does not take a tail pointer
and therefore the pointer is always left hanging. If the number of elements
ever drops to zero the queue becomes corrupted.
Added osi_QRemoveHT to be used whenever head and tail pointers are used.
Updated all callers in afsd.
