This patch adds systemd service files. It is possible to start and
enable multiple instances (per monid, osdid, mds name), e.g.
# systemctl start ceph-mon@node01
# systemctl enable ceph-mon@node01
# systemctl start ceph-osd@0
# systemctl enable ceph-osd@0
The ceph cluster can be set in the system config file:
/etc/sysconfig/ceph
adding or editing the CLUSTER environment variable.

Add libkrbd libtool convenience library to provide an interface for
mapping and unmapping rbd images programmatically. This will be used
by the rbd binary itself and the librbd_fsx testing tool.
libkrbd takes care of the kernel module stuff (common/module.h) and
makes use of libudev to be able to properly wait for block device
creation and deletion and tell which block device got assigned by the
kernel to the newly created mapping.

Clients can make use of these directories, and ceph-common is required by
ceph, so nothing should break here.
Change the purge postrm script to be for ceph-common (it does nothing else).

The older versions of ceph-common (ceph CLI, in particular) can't talk to
newer clusters. The primary change happened with dumpling when the new
CLI and rest-api changes were made. Although in reality ceph doesn't
care what version of ceph-common is installed, in practice this forces
ceph-common to get upgraded along with ceph and avoids some user pain.

Introduce XfsFileStoreBackend class, currently the only filestore
backend implementing SETALLOCHINT op. This commit adds a build-time
dependency on libxfs as xfs-specific ioctl (XFS_IOC_FSSETXATTR /
XFS_XFLAG_EXTSIZE) is used to implement the new set_alloc_hint()
method.

python-ceph does not require requests, but ceph-common does (for ceph-brag).

(cherry picked from commit 9a0ef6a181)
The binaries file name have changed and need to be updated in the
packaging files for deb and rpm. Fix a few leftovers as well.

It loads a designated erasure-code plugin and calls its
methods. It is convenient to figure out and tune the number of data
chunks, the size of an aligned chunk etc. For instance:
ceph_erasure_code \
--parameter erasure-code-plugin=jerasure \
--parameter erasure-code-directory=.libs \
--parameter erasure-code-technique=reed_sol_van \
--parameter erasure-code-k=2 \
--parameter erasure-code-m=2 \
--all
displays the chunk size when encoding an object of 1024 bytes.
get_chunk_size(1024) 512
get_data_chunk_count 2
get_chunk_count 4
