With this change doxygen will create SVG graphics (instead of png) which
are zoomable due these are vector graphics.

This commit is based on a suggestion from Bill Bennet.
With this change doxygen is also creating a call and caller dependency
graphic for global functions. This is helpful for understanding the mode
of action inside the libcoap.

The make target for creating the distribution tarball (make dist) was
broken some commits ago within the changes in the doc/ subdirectory. The
reason for this is that simple Doxygen has to be runs ones before the
automatism can pick up the files. automake uses dist_pkgdist_DATA as
trigger. So we have to use that variable.
Changing up the makefile template so the call for 'dist_pkgdist_DATA'
*and* 'all-local' is calling 'doxfile.stamp' so fist Doxygen is running.
By doing this also clean up a little bit and prepare the build for be
able to run out of the tree.
Doxygen supports the creation of DOT graphics, but this depends on the
existence of the 'dot' binary on the build host. Adding a check for dot
and disable the support within the Doxygen file for DOT graphics if dot
can't be found.
To install the doxygen output, which is generated within doc/html/,
adding the needed checks for the doxygen binary to configure.ac and also
adding the needed doc/Makefile.am file.
Finally tuning doc/Doxyfile.in to let the autotools write the needed
informations into this file while generating the finally created
doc/Doxyfile.
