trace readdir

[droundy]

For fac/bigbro, readdir is an important operation to trace. It's needed if you have a build rule such as:

echo *.c > file.dat

in which case the rule needs to be rebuilt if a new file is created in that directory.

Would it require a separate operation type or is a 'read' of the directory enough?

[droundy]

Different system calls are used for reading directories. I would output it
as a separate type as well (and do so), since tools might want to ignore
changes to directories, and it saves effort to treat them as distinct, to
avoid the need for the caller to stat each reported read.
