For HDD osd backend, a alloc hint is good for local filesystem to ensure
extent continuous. But for SSD, the available capacity is useful and
precious, user may not expect lots of capacity is used by reserving.
Then ssd is good for random rw.

Fedora, suse as well as centos >= 7 and rhel >= 7
use the same name for python-sphinx so add these
conditionals.
Note: Until OBS supports EPEL I cant test builds on
centos and rhel so this extention of build deps is
untested by Owen Synge.

Original fix used %{_mandir}/*/* but this could potentially lead to ambiguity
as ceph rpm spec file contains many man pages for different packages.

This should make newer gcc releases happier in their default configuration.
kernel.org is now distributing tarballs as .xz files so we change to that
as well when decompressing (it is supported by Ubuntu Precise so we should
be all good).

Move all the cruft that is necessary to compile shared files both in
kernel and userspace into a new crush_compat.h. Also add a stub for
div64_s64() and limits for linux fixed width types.

- map->choose_tries is not in the kernel
- 64-bit/64-bit in the kernel needs a special helper for 32-bit
architectures, crush_compat.h provides a stub
- INT64_MIN is not in the kernel, crush_compat.h provides S64_MIN
- use dprintk inside DEBUG_INDEP sections
No functional changes.

Analogous to those from the old-style mds tell. Also
add an 'ls' that gives you the frags in the same format
that frag_t::parse expects them, so that it's a bit
less obscure to use.

This reverts mapper.c hunks of 830752a528 ("doc: fix doxygen
warnings"). It is shared with the kernel and uses kernel-doc for
in-code documentation. If doxygen warnings are an issue, we should
probably just exclude the 7 shared files in Doxyfile - we don't have
@file in these files or EXTRACT_ALL/EXTRACT_STATIC in Doxyfile, which
means these files are essentially skipped as there is no C++ stuff in
them.

Fix some recently introduced style issues in crush_ln_table.h,
crush.[ch], hash.[ch], and mapper.[ch]. These files are shared with
the kernel, so we need to at least not introduce anything new -
checkpatch is pretty unhappy as it is.
