* Check for {{{dlfcn.h}}} in the self component's configure.m4 (also clean up the .m4 a bit.
* Adjust the priority of the BLCR component so that the self component has a higher priority (if the application went to the trouble of writing the routines, why not use them.) The 'self' component checks for the appropriate functions during query, so it know if it -can- be used during component selection.
* Adjust some copyrights that I missed before
* Fix a warning when casing the result of dlsym() into a function pointer. There is a bit of pointer magic to make this happen (thanks to the following website, and RedHat EL 4 man pages for illustrating it:
http://www.opengroup.org/onlinepubs/009695399/functions/dlsym.html
Passing to Jeff for a final review of the patch before moving to v1.3.
