* With the addition of serdbg, the standard polled I/O functions
for gdbstub and/or printk are optionally routed to any termios-aware
device driver, that supports polled mode. See libmisc/serdbg/README.
* serdbg/Makefile.am, serdbg/README, serdbg/serdbg.c, serdbg/serdbg.h,
serdbg/serdbgcnf.h, serdbg/serdbgio.c, serdbg/termios_printk.c,
serdbg/termios_printk.h, serdbg/termios_printk_cnf.h,
serdbg/.cvsignore: New files.
* configure.ac, Makefile.am, wrapup/Makefile.am: Modified to
reflect addition.
