[sheepdog] [ANNOUNCE] periodical clang analysis of sheepdog

[Hitoshi Mitake]

Hi sheepdog developers,

This is an announce of a page for periodical clang analysis of
sheepdog source tree:
https://github.com/sheepdog/sheepdog/wiki/clang-analysis-of-sheepdog

The page provides various static analysis results of sheepdog source
tree and detect problems like possibility of null pointer
dereference. In the past, the analysis resulted an important bugfix:
https://github.com/sheepdog/sheepdog/commit/ddf9a8af
So I would suggest checking the page when you find problems during
testing sheepdog.

The page is provided and maintained by  Marcin Mirosław. Thanks a lot,
Marcin!
