Add static_ptr, a pointer-like class that contains its own storage,
avoiding use of the heap.
The full range of *_pointer_cast functions are included.

pthread_rwlockattr_setkind_np() is a GNU extension of libpthread. and
Tianshan Qu pointed out, we cannot use
ifdef(PTHREAD_RWLOCK_PREFER_WRITER_NONRECURSIVE_NP) to detect the
availability of this function, because it's an enum not a macro. so,
like other *_np() extensions, we check this one also using cmake at
the configure phase.

100MB will be allocated for journal, and the remaining 100MB is for data
device. taking the inode into consideration, there will be approximately
87988 kB available for the activated OSD. and it will complain with a
"nearfull" state.

it does not matter if we chown/restorecon before or after the rename,
but the logging message looks better this way: instead of fixing the
.tmp files, we are updating the attributes of the dest files w/o
.${pid}.tmp extension.

normally, if we care about the output of ceph-disk, we expect a json
string, and ceph-disk sends the output to stdout, and errors/warnings
to stderr. so everything works as expected. and the test should also
follow this tradition. for example, if deprecated warnings are printed,
the warning message should not be collected along with the json string.

To bound the degree to which an RGW instance can go out to lunch if
the watch/notify breaks down, force refresh of any cache entry over a
certain age.
Fifteen minutes by default, and expiration can be turned off entirely.
This is separate from the LRU. The LRU removes entries based on the
last time of access. This expiration patch forces refresh based on the
last time they were updated.

If the OSD informs us that our bucket info is out of date when we need
to write, we should have a way to update it.
This template function allows us to wrap relevant sections of code so
they'll be retried against new bucket info on -ECANCELED.

Sometimes operations fail with -ECANCELED. This means we got raced. If
this happens we should update our bucket info from cache and try again.
Some user reports suggest that our cache may be getting and staying
out of sync. This is a bug and should be fixed, but it would also be
nice if we were robust enough to notice the problem and refresh.
So in that case, we invalidate the cache and fetch direct from the
OSD, putting a warning in the log.

You have included file(s) internally used by a version control system in the
package. Move these files out of the package and rebuild it.
Note: the backslash has to be doubled up for the regex to make
it through CMake.
