Subject: tools/erasure-code: build without "using namespace std"
X-Git-Tag: v17.1.0~1121^2~7
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=f6b157e946b7cdfc32481707fb655fccd19753a6;p=ceph.git

tools/erasure-code: 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.
