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).

- 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.

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.

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.

Given that crush_{addition,multiplication}_is_unsafe() are only used
for compiling maps, they have no business in crush.c which is shared
with the kernel.

VirtualBox has some files with weird
permissions in its /usr/lib, which was
tripping up this usually-safe operation

PGMonitor::map_pg_creates() is the only caller that passes sumonly=true,
which is necessary to avoid modifying creating_pgs while it is iterating
over it. However, everything else we *do* want to update--especially the
osd counts.
Rename the arg and skip only the creating bit.
