* libmisc/serdbg/termios_printk.c, libmisc/serdbg/termios_printk.h:
Fixed incompatible return value.
* libmisc/cpuuse/cpuusagereport.c: Changed output format.
* libmisc/Makefile.am, libmisc/monitor/mon-editor.c: New file.
* libmisc/capture/capture-cli.c, libmisc/monitor/mon-command.c,
libmisc/monitor/mon-monitor.c, libmisc/monitor/mon-object.c,
libmisc/monitor/mon-prmisc.c, libmisc/monitor/mon-symbols.c,
libmisc/monitor/monitor.h, libmisc/shell/cat_file.c,
libmisc/shell/cmds.c, libmisc/shell/internal.h,
libmisc/shell/main_help.c, libmisc/shell/shell.c,
libmisc/shell/shell.h, libmisc/shell/shell_cmdset.c,
libmisc/shell/shell_getchar.c, libmisc/shell/str2int.c: Various global
data is now read only. Added 'const' qualifier to many pointer
parameters. It is no longer possible to remove monitor commands.
Moved monitor line editor into a separate file to avoid unnecessary
dependencies.
