Josef Söntgen b51ae104c2 qemu-usb: use bounce buffer to access DMA memory 
The former implemention assumed that the guest physical memory is
mapped continously. This, however, is not true. Writing larger
files to an USB stick with a Windows 10 guest would therefore lead
to data corruption.

The current implementation uses a bounce buffer to copy the data
to and from the guest physical memory and leaves dealing with the
memory mappings entirely up to the VMM.

Fixes #4017.

This directory contains ports of popular 3rd-party applications to Genode.

The 'ports' repository follows the line of the 'libports' repository.
For instructions about downloading and building 3rd-party applications,
please refer to 'libports/README'.
