[PATCH] new file_relay interface

Hi,

just for completeness, here's the file_relay interface. You can request "Sources" which will give a gzipped cpio archive in return. The function gives an iphone_connection_t which has to be used to receive the data. See the docs for further details.
The following are valid sources:
AppleSupport Network VPN WiFi UserDatabases CrashReporter tmp SystemConfiguration

You can retrieve one or more of them at the same time. The resulting archive will contain all of the data (with the full folder structure as found on the device).

I added a small test program to the dev folder giving a dump.cpio.gz file for the above sources.
