	Make sure bindctl private files are non readable to anyone except
	the owner or users in the same group.  Note that if BIND 10 is run
	with changing the user, this change means that the file owner or
	group will have to be adjusted.  Also note that this change is
	only effective for a fresh install; if these files already exist,
	their permissions must be adjusted by hand (if necessary).

	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.

	The host tool is renamed to b10-host. While the utility is
	a work in progress, it is expected to now be shipped with

	rewritten in C++ from scratch and using BIND 10's libdns++.
	It now supports the -a (any), -c class, -d (verbose) switches
	and has improved output.

	Added the HTTP/XML interface (b10-stats-httpd) to the
185
186
	statistics feature in BIND 10. b10-stats-httpd is a standalone
	HTTP server and it requests statistics data to the stats
187
	daemon (b10-stats) and sends it to HTTP clients in XML
188
189
	format. Items of the data collected via b10-stats-httpd
	are almost equivalent to ones which are collected via
190
191
	bindctl. Since it also can send XSL (Extensible Stylesheet
	Language) document and XSD (XML Schema definition) document,
192
193
	XML document is human-friendly to view through web browsers
	and its data types are strictly defined.

	Solved incorrect datetime of "bind10.boot_time" and also
	added a new command "sendstats" for Bob. This command is
	to send statistics data to the stats daemon immediately.
	The solved problem is that statistics data doesn't surely
	reach to the daemon because Bob sent statistics data to
	the daemon while it is starting. So the daemon invokes the
	command for Bob after it starts up. This command is also
	useful for resending statistics data via bindctl manually.
