- Remove the printf support leaving the direct printk support configured
with TESTS_USE_PRINTK and all other output goes via a buffered vsniprintf
call to printk.
- Control the test's single init for functions and global data with
TEST_INIT and not CONFIGURE_INIT. They are now separate.
Updates #3170.
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.
