Qemu pipe access with parameter
In current implementation, each qemu_pipe read/write buffer requires severals MMIO operations to pass down the parameters like buffer address, pipe, length etc. This has impacts on emulator performance when running under the HAXM environment because each MMIO access cause expensive transition from guest to HAXM driver and QEMU process. To reduce the overhead, we put the parameter into a buffer without causing MMIO access, and then invoke a single MMIO operation needed for the access command.
