net/syncthing: put back patch to avoid upgrading, avoid stripping

We don't want the built in upgrading, we want to do it via ports/packages, so
put back the patch to make it always say the version in use is current.

Avoid stripping as stripping go binaries is explicitly unsupported, dangerous
and known to cause problems.
- Update libplist to 1.11.
- Split libusbmuxd.so into comms/libusbmuxd and update to 1.0.9.
- Update libimobiledevice to 1.1.6.
- Update usbmuxd to Git snapshot (~1.0.9).
- Document usbmuxd upgrade process.

This marks an important refactoring effort for proper iOS 7 support.
It's packed with new features, tools, speed improvements, code
refactoring, crash fixes, memory leak fixes and much more.
