libmisc: More useful default configuration
The dummy.c was a de-facto default configuration. Rename it to default-configuration.c. Use unlimited objects and the stack checker. This makes it easier for new RTEMS users which will likely use this file if they just work with the usual main() function as the application entry point. Provide proper arguments for main() using the BSP command line. Add spare user extensions and drivers. Do not initialize the network by default. Delete bspinit.c.

-A relocatible objects which contains a dummy configuration for RTEMS.
-
-Helps linking standard c-program code with RTEMS, which shall *not* be run
-on a target, such as configure script code fragments generated by autoconf's
-AC_TRY_LINK.
-
-Example:
-
-tar xzvf somepkg.tar.gz
-cd somepkg
-
-LDFLAGS=/usr/local/rtems/<cpu>-rtems/<bsp>/lib/dummy.rel \
-CC="<cpu>-rtems-gcc \
