rtems/cpukit/configure.ac
Sebastian Huber a6e39d4a59 Update Doxyfile to Doxygen 1.8.15 
Generate Doxygen output in doc and ignore this directory in Git.  Add
RTEMS logo.  The Doxygen documentation is now built using the source
tree.  Just invoke "doxygen" in the top-level source directory.

The Doxyfile works also with at least Doxygen 1.8.13 and Doxygen 1.8.14.

Update #3705.
