Numerous changes which in total greatly reduced the amount of source

code in each BSP's bspstart.c.  These changes were:

  + confdefs.h now knows libio's semaphore requirements
  + shared/main.c now copies Configuration to BSP_Configuration
  + shared/main.c fills in the Cpu_table with default values

This removed the need for rtems_libio_config() and the constant
BSP_LIBIO_MAX_FDS in every BSP.  Plus now the maximum number of open
files can now be set on the gcc command line.
