Changes included in this set:
* Added strlcat() and strlcpy() from OpenBSD, always use them if the
system does not have them built in.
* Changed an array of PATH_MAX size allocated in the stack, to a dynamically
allocated buffer from heap. This should reduce memory usage a bit.
* Simplify code that implemented a homegrown realpath(3) implementation,
simply use realpath(3).
* If compiler supports -fstack-protector, build all code with
-D_FORTIFY_SOURCE=2 and --param ssp-buffer-size=1 so that all
buffers are protected.
doxygen and graphviz are required. It's disabled by default, use
the BUILD_API_DOCS make(1) argument to enable it.
