The two previous patches have been merged upstream, so they have been
deleted here. Another patch (picked from upstream) has been added to fix
the build with thread-less toolchains.
Libiio v0.7 provides two new backends, a USB backend (using libusb-1.0)
and a serial backend (using libserialport).
Additionally, it is now possible to compile libiio with thread-less
toolchains. In that case, thread safety is disabled.
