delegate_helpers now builds corretly by recompiling depencies with -fPIC before bundling the shared-library
Moved -fPIC from Utils to CloudSupport and only when building shared libraries
Temorary linking problem fix for delegate_helpers.OSX and linux differ in the way they treat undefined reference in shared library.A smarter way to avoid bundling objects common to libgrapes in delegate_helpers shared libraries is needed.
Dynamic linking problem: delegate_helpers cannot find symbols related to request_handler and fifo_queue in libgrapes
Added OSX specific linking options and removed objects dependencies on shared libraries
libs3_delegate_helper uses request_handler to manage blocking operations
Added delegate cloud helper for Amazon S3 through libs3
Moved cloud specific sources to CloudSupport directory
