ceph-disk: set guid if reusing a journal partition

When reusing a journal partition (e.g. /dev/sda2) we should set a
new partition guid and link it correctly with the OSD. This way
the journal is symlinked by its persistent name and ceph-disk list
works correctly.

Objecter: resend linger ops on any interval change

Watch/notify ops need to be resent after a pg split occurs, as well as
a few other circumstances that the existing objecter checks did not
catch.

Refactor the check the OSD uses for this to add a version taking the
more basic types instead of the whole OSD map, and stash the needed
info when an op is sent.

client: fix I_COMPLETE_ORDERED checking

Current code marks a directory inode as complete and ordered when readdir
finishes, but it does not check if the directory was modified in the middle
of readdir. This is wrong, directory inode should not be marked as ordered
if it was modified during readddir

The fix is introduce a new counter to the inode data struct, we increase
the counter each time the directory is modified. When readdir finishes, we
check the counter to decide if the directory should be marked as ordered.

client: cast m->get_client_tid() to compare to 16-bit Inode::flushing_cap_tid

m->get_client_tid() is 64 bits (as it should be), but Inode::flushing_cap_tid
is only 16 bits. 16 bits should be plenty to let the cap flush updates
pipeline appropriately, but we need to cast in the proper direction when
comparing these differently-sized versions. So downcast the 64-bit one
to 16 bits.

client: allow xattr caps in inject_release_failure

Because some test environments generate spurious
rmxattr operations, allow the client to release
'X' caps.  Allows xattr operations to proceed
while still preventing client releasing other caps.

qa: avoid qa/workunits/cephtool/test.sh unstability

For testing injectargs a configuration option was changed that has side

replaced with a configuration option that cannot have adverse side

rbd: Fix the rbd export when image size more than 2G

When using export <image-name> <path> and the size of image is more
than 2G, the previous version about finish() could not handle in
seeking the offset in image and return error.

This is caused by the incorrect variable type. Try to use the correct
variable type to fixed it.

I use another variable which type is uint64_t for confirming seeking
and still use the previous r for return error.

uint64_t is more better than type int for handle lseek64().
