Instead of just ,. Currently "foo.com, bar.com" will fail because of the
space after the comma. This patches fixes that, and makes all delim
chars interchangeable.

We introduced a bug on the monitor store a couple of commits back that
would trigger a EEXIST error message when the store tried to make sure
a directory exists by trying to 'mkdir' it.
We now check if 'errno' is EEXIST and, if so, we ignore the error.

Stat of symlinks that are relative to their location
would return -ENOENT because the symlink target is
being appended to the path rather than replacing it.
This fix replaces the symlink component with the path
of the symlink target (in the case that its a relative
symlink), and avoids updating the inode to point the
symlink (keeps at the parent).

lstat is meant to not follow symbolic links in
the given path, whereas stat does. This adds a
stat function to Client and libcephfs and changes
the behavior of lstat to not follow symlinks.

Users of the libcephfs api (fuse in particular)
don't check the mode against the open flags. This
commit does the proper checks to grant/deny access
to the file. The check_mode() function constructs
a requested mode based on the flags, and compares that
to the mode of the file.

- don't delete the pool during the run
- ignore create error codes (may succeed for return EEXIST)
- use a unique pool name
Signed-off-by: Sage Weil <sage@inktank.com>
We need to verify that a pool really doesn't exist before erroring out. In
particular, we need to make sure it doesn't exist in an osdmap we haven't
seen yet (future from this client's perspective, but still strictly in the
past). The code to do this before was fragile and broken. A 'map latest'
check would go out for every map epoch we process, and we would clear out
our check state on the first reply. Also, we would have to win the race
to get a check back for the exact map that we have before we would succeed.
Instead:
- If we haven't already done so, ask the monitor for the latest map. This
establishes an upper bound on the current map at the time the request
was queued.
- On reply, make note of this map.
- Thereafter, we can fail the request if at any point we call into the
check_*_pool_dne() helper and the current map is >= that bound map. The
caller performs the actual check for whether the pool exists or not.
Among other things, this fixes testrados_list_parallel.

This was only added so that crash dumps pasted into redmine would link
properly, but those links don't work in redmine right now anyway, so drop
it. The prefix makes it harder to manually cut and paste.

Previously, the messenger would queue messages for a destination that
didn't exist when you were a server; that changed a while back with the
wip-msgr merge (circa v0.52). The result is that when we force open
client sessions and queue messages, they are dropped on the floor and the
client--when it does connect--gets confusing stuff from the MDS.
Instead, explicitly queue and send these messages. Also, *always* send
via the Connection* instead of the inst.

When we release caps, clear them out of implemented as well, unless we
still hold references. Otherwise implemented ends up holding all sorts of
extra caps (e.g., when nothing is getting revoked), leading to confusion
later down the line.
This now mirrors the kernel code.
