[qemu]: Move qemu_pipe.h from include/system/ directory.
The <hardware/qemu_pipe.h> header isn't related to any loadable
hardware module, this patch thus relocates it to <system/qemu_pipe.h>
which is a much more logical location.
Note the following changes:
- The pipe name must begin with the 'pipe:' prefix to avoid an
un-necessary snprintf() and buffer copy.
- Does not probe for the obsolete /dev/goldfish_pipe device, i.e.
only use /dev/qemu_pipe instead.
- Use QEMU_PIPE_DEBUG() instead of D() as the debugging macro.
+ Update ADB to use the newest <system/qemu_pipe.h>
+ Add qemu_pipe_frame_send() and qemu_pipe_frame_recv() utility
functions which replace the obsolete qemud_channel_send() and
qemud_channel_recv() from the defunct <hardware/qemud.h>
header.
