* libmisc/Makefile.am, libmisc/monitor/mon-object.c, libmisc/monitor/monitor.h, sapi/include/confdefs.h, sapi/include/rtems/config.h, sapi/include/rtems/io.h, sapi/src/exinit.c, sapi/src/io.c: Eliminate maximum_drivers configuration parameter since it was used to configure a no longer used feature. Device names are now part of the filesystem not in a table. This also eliminated the variables _IO_Number_of_devices and _IO_Driver_name_table from RTEMS as well as the memory allocation used to populate _IO_Driver_name_table. * libmisc/monitor/mon-dname.c: Removed.
