CID 717083: Resource leak (RESOURCE_LEAK)

to.

CID 716911: Dereference after null check (FORWARD_NULL)
At (5): Passing null pointer "b" to function "strncat(char *, char
const *, size_t)", which dereferences it. (The dereference is assumed
on the basis of the 'nonnull' parameter attribute.)

CID 716937: Overflowed return value (INTEGER_OVERFLOW)
At (3): Overflowed or truncated value (or a value computed from an
overflowed or truncated value) "offset" used as return value.
CID 717012: Unintentional integer overflow (OVERFLOW_BEFORE_WIDEN)
At (1): Potentially overflowing expression "1 << obj_order" with type
"int" (32 bits, signed) is evaluated using 32-bit arithmetic before
being used in a context which expects an expression of type "uint64_t"
(64 bits, unsigned). To avoid overflow, cast the left operand to
"uint64_t" before performing the left shift.

The README provides a list of packages needed to successfully
configure ceph. uuid-dev and libatomic-ops-dev are missing from
the list.

We want to avoid a race like:
- entry() starts, populates pfd with listen_sd, gets past !done check
- stop() does shutdown + close on listen_sd
- someone else opens a new fd
- entry() thread calls poll(2) on wrong sd
- stop() calls join, waits forever for entry thread

Should just return true. This way we don't need higher level
functions to be aware of system buckets. Also, don't use
marker.empty() to test for system bucket, use bucket_is_system().

The previous fix (0f7c516f3e) breaks osd startup with -k. This one
from dmick just tells the ceph-mon which keyring to use through the
command line rather than moving the keyring path to the [global]
section of the config file.

When handling master request with slaves, the mds could crash
after receiving all slaves' commit acknowledgement, but before
journalling the ECommitted. Current MDS recovery code does not
handle this case correctly, the request will be left in
LogSegment's uncommitted_masters after recovery is finished.
It prevents LogSegment from being trimmed. The fix is find and
clean up request of this kind when recovery enters rejoin stage.

Defines the macro CEPH_INO_DOTDOT (to 3) and uses it as the top-level
parent directory (..) inode number. The value of 2 is already taken
by the .ceph hidden directory.

In the lowlevel fuse api, the current (.) and parent (..) entries
must be added manually in a readdir call. For the root directory
the parent is not a ceph inode, so we give it a fake inode value
(2) and intercept that inode on a getattr.
Fixes: #1957
