Joachim Nilsson 32587d341c Overhaul build system and add support for disabling inetd support.
This patch adds support for a configure script and with it
support for disabling inetd support.  See the output from

    ./configure --help

* Add configure script
* Sprinkle #ifdef fairy dust on svc.c when inetd support is disabled
* Use GCC built-in autodep calculator (-MMD -MP)
* Fix name space issue with include files, use relative paths
* Disable username/group name to uid/gid functions in static builds
* Bug out (error) if a user tries to build the bootmisc plugin static

Possibly fixes GitHub issue #5 and issue #6.

NOTE: The static build has not received any testing at all!
