[bugzcxx-devel] fixes some api doxygen files

[BugzCXX D. <bug...@li...>]

Another trivial change. I have updated old doxygen configuration files
with `doxygen -u' . It suppresses the warnings and knocks off old
variables form file. In keeping with old file I have removed out
comments.

Now our build is very clean.
