Hi,

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-cmds.c:        Added -file-list-exec-source-file command.
 * mi-cmds.h:        Added -file-list-exec-source-file to proto list.
 * gdbmi.texinfo:    Document -file-list-exec-source-file.
 * mi-file.exp:      Added testcase to test -file-list-exec-source-file. 

Also, do you think it would be good if the function 
-file-list-exec-source-file optionally took an argument ( a filename ).
If it reiceived an argument, it would return the absolute path to that
file.

I think the normal way a front end gets the absolute path to a file now
is,
1. list filename.c
2. info source
3. parse the output looking for 'Located in '

This optional argument would solve that problem.

Thanks,
Bob Rossi
