[sheepdog] [ANNOUNCE, CAUTION] sheepdog stable release v0.8.1_rc0

[Hitoshi Mitake]

Hi sheepdog users and developers,

I released v0.8.1_rc0 of stable branch. You can download a source
archive from these URLs:
tar.gz: https://github.com/sheepdog/sheepdog/archive/v0.8.1_rc0.tar.gz
zip: https://github.com/sheepdog/sheepdog/archive/v0.8.1_rc0.zip

This update contains a bunch of important improvements related to
packaging, logging, controling under heavy I/O, memory leaks, etc.

I have to emphasis on the point that updating from v0.8.0 to
v0.8.1_rc0 requires "-u" option, because it contains updating store
format. Sorry for inconvenience but the format update is a necessary
change for clusters which store many objects.

If no one disagrees about this release candidate in 2 days, it will be
v0.8.1 officially.

Below is a summary of commits:
