This change essentially adds the command -file-list-exec-source-file to
the mi commands.

* mi-cmd-file.c:    Added file to implement mi file commands.
* mi-getopt.c:      Added mi_valid_noargs to verify if a set of
                    parameters passed to an MI function has no arguments
* mi-getopt.h:      Prototyped mi_valid_noargs
* mi-cmds.c:        Added -file-list-exec-source-file command.
* mi-cmds.h:        Added -file-list-exec-source-file to proto list.
* doc/gdb.texinfo:  Document -file-list-exec-source-file.
* mi-file.exp:      Added testcase to test -file-list-exec-source-file.

Thanks,
Bob Rossi
