OSX support with DYLD_INSERT_LIBRARIES/interposing

[GoogleCodeExporter]

While OSX has dtruss which has similar output to strace, it (and anything else 
using DTrace) requires root access making it impractical.  Here is an 
alternative implementation using DYLD_INSERT_LIBRARIES, similar to LD_PRELOAD 
on Linux, to detect what files are being accessed.  This requires bundling C 
code into fabricate.py, but seems to work correctly and quickly (probably 
faster than strace as it doesn't need to use regular expressions).

Hi all, what's the current status of Fabricate on OS X? This issue is the only discussion I can find around OS X. Is this code in a git branch somewhere?

I would love to use Fabricate on OS X. I can test it, and help develop it if necessary.

Hi @iainmerrick,

Thanks for the offer! We're currently working through the issue and PR backlog.
Hopefully we will create some milestones for development soon.

All the contributors are pretty time-constrained at the moment, so any help
in the form of issues or PR's would be appreciated.

I can take this one as I've made it work in the past using the patches in the thread.
