Subject: crush: build without "using namespace std"
X-Git-Tag: v17.1.0~1121^2~12
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=573fd9804ced51fd825e745857c92b8f80ddcaa3;p=ceph.git

crush: build without "using namespace std"

* add "std::" prefix in headers
* add "using" declarations in .cc files.

so we don't rely on "using namespace std" in one or more included
headers.
