ceph_rest_api.py: create own default for log_file

common/config thinks the default log_file for non-daemons should be "".
Override that so that the default is
/var/log/ceph/{cluster}-{name}.{pid}.log
since ceph-rest-api is more of a daemon than a client.

It is possible that we begin the paxos recovery with an uncommitted
value for, say, commit 100. During last/collect we discover 100 has been
committed already. But also, another node provides an uncommitted value
for 101 with the same pn. Currently, we refuse to learn it, because the
pn is not strictly > than our current uncommitted pn... even though it is
the next last_committed+1 value that we need.
There are two possible fixes here:
- make this a >= as we can accept newer values from the same pn.
- discard our uncommitted value metadata when we commit the value.
Let's do both!

When removing a bucket metadata entry we first unlink the bucket
and then we remove the bucket entrypoint object. Originally
when unlinking the bucket we first overwrote the bucket entrypoint
entry marking it as 'unlinked'. However, this is not really needed
as we're just about to remove it. The original version triggered
a bug, as we needed to propagate the new header version first (which
we didn't do, so the subsequent bucket removal failed).

Some distro's have a lack of ltp-kernel packages and all we need is
fstress. This just modified the shell script to download/compile
fstress from source and copy it to the right location if it doesn't
currently exist where it is expected. It is a very small/quick
compile and currently only SLES and debian do not have it already.

This patch adds a few ENV variables, so you can use vstart.sh
multiple time to launch multiple clusters
CEPH_DIR -> The working directory of the cluster
CEPH_DEV_DIR -> the dev directory of the cluster
CEPH_OUT_DIR -> the output directory of the cluster
CEPH_RGW_PORT -> the default radosgw port to start with
All theses new variables are set to default values if not specified,
which ones does not change the previous behaviour of vstart.sh

CephFS currently deadlocks under CTDB's ping_pong POSIX locking test
when run concurrently on multiple nodes.
The deadlock is caused by failed removal of a waiting_locks entry when
the waiting lock is merged with an existing lock, e.g:
Initial MDS state (two clients, same file):
held_locks -- start: 0, length: 1, client: 4116, pid: 7899, type: 2
start: 2, length: 1, client: 4110, pid: 40767, type: 2
waiting_locks -- start: 1, length: 1, client: 4116, pid: 7899, type: 2
Waiting lock entry 4116@1:1 fires:
handle_client_file_setlock: start: 1, length: 1,
client: 4116, pid: 7899, type: 2
MDS state after lock is obtained:
held_locks -- start: 0, length: 2, client: 4116, pid: 7899, type: 2
start: 2, length: 1, client: 4110, pid: 40767, type: 2
waiting_locks -- start: 1, length: 1, client: 4116, pid: 7899, type: 2
Note that the waiting 4116@1:1 lock entry is merged with the existing
4116@0:1 held lock to become a 4116@0:2 held lock. However, the now
handled 4116@1:1 waiting_locks entry remains.
When handling a lock request, the MDS calls adjust_locks() to merge
the new lock with available neighbours. If the new lock is merged,
then the waiting_locks entry is not located in the subsequent
remove_waiting() call because adjust_locks changed the new lock to
include the old locks.
This fix ensures that the waiting_locks entry is removed prior to
modification during merge.
