237. [bug] naokikambe
Resolved that the stats module wasn't configurable in bindctl in
spite of its having configuration items. The configuration part
was removed from the original spec file "stats.spec" and was
placed in a new spec file "stats-schema.spec". Because it means
definitions of statistics items. The command part is still
there. Thus stats module currently has no its own configuration,
and the items in "stats-schema.spec" are neither visible nor
configurable through bindctl. "stats-schema.spec" is shared with
stats module and stats-httpd module, and maybe with other
statistical modules in future. "stats.spec" has own configuration
and commands of stats module, if it requires.
(Trac#719, git a234b20dc6617392deb8a1e00eb0eed0ff353c0a)
236. [func] jelte

It also has improved error handling when communicating with the
