Improve trace events used by readahead

[Scott James Remnant (Canonical)]

The trace event patch I wrote during karmic gave readahead events for each open() syscall, along with the filename.

It turns out that exec() is kinda useful too. I've updated the patch to add these, and for completeness uselib() as well.

Please apply in an SRU so we can ship better readahead!

Accepted linux into karmic-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

I confirm that ureadahead still works fine with this kernel.
