If you attempt to pipe commands in to bindctl and the session is not
interactive (i.e it is not a TTY) then do not attempt to read the user
name and password.

As per review added a comment about the use of $ac_header_preproc.

This is to set the location of the css stylesheet.
Previously it pointed to a path in the source directory.
By default, this was "./" so was okay as a location via HTTP.
But when built using a different source directory, then
the full source directory ended up as a reference on the webpage
so then style's didn't work.

I briefly discussed this on jabber yesterday but didn't get an okay.
It is a minor fix, so committing per my discretion.

(minor fix, committed without review)

The comment at the end of adding to AM_CXXFLAGS was making the total
line too long, and the automake tool was splitting the line. This meant
that the macro assignment had an escaped comment, which the BSD make
interprets differently to GNU make (the latter swallows the next line as
part of the comment, whereas the former doesn't).

	ChangeLog

When bind10 is run in verbose mode, as is indicated to the user by
certain error messages, do not redirect b10-msgq's STDOUT to /dev/null
so that the user can see the actual cause for startup failure.

No ChangeLog entry required.

When there is an error connecting to the message queue socket file
because it wasn't cleaned up properly, and we know the name of the
socket file, display its name as part of the error message.

No ChangeLog entry required.

Also additional trivial fixes applied: fixed the Changelog entry number
for #3211 and git commit id for #3199.

 - ChangeLog clarified
 - Comments in option_definition.h corrected

Okayed on jabber.
