[SRU] 0.80.7 stable update

New stable release of Ceph for trusty and utopic only; already in vivid:

v0.80.7 Firefly

This release fixes a few critical issues with v0.80.6, particularly with clusters running mixed versions.

We recommend that all v0.80.x Firefly users upgrade to this release.

For more detailed information, see the complete changelog.
Notable Changes

    osd: fix invalid memory reference in log trimming (#9731 Samuel Just)
    osd: fix use-after-free in cache tiering code (#7588 Sage Weil)
    osd: remove bad backfill assertion for mixed-version clusters (#9696 Samuel Just)

v0.80.6 Firefly

This is a major bugfix release for firefly, fixing a range of issues in the OSD and monitor, particularly with cache tiering. There are also important fixes in librados, with the watch/notify mechanism used by librbd, and in radosgw.

A few pieces of new functionality of been backported, including improved ‘ceph df’ output (view amount of writeable space per pool), support for non-default cluster names when using sysvinit or systemd, and improved (and fixed) support for dmcrypt.

We recommend that all v0.80.x Firefly users upgrade to this release.
