/**
* QTest Protocol
*
* Line based protocol, request/response based. Server can send async messages
* so clients should always handle many async messages before the response
* comes in.
*
* Valid requests
*
* Clock management:
*
* The qtest client is completely in charge of the QEMU_CLOCK_VIRTUAL. qtest commands
* let you adjust the value of the clock (monotonically). All the commands
* return the current value of the clock in nanoseconds.
*
* > clock_step
* < OK VALUE
*
* Advance the clock to the next deadline. Useful when waiting for
* asynchronous events.
*
* > clock_step NS
* < OK VALUE
*
* Advance the clock by NS nanoseconds.
*
* > clock_set NS
* < OK VALUE
*
* Advance the clock to NS nanoseconds (do nothing if it's already past).
*
* PIO and memory access:
*
* > outb ADDR VALUE
* < OK
*
* > outw ADDR VALUE
* < OK
*
* > outl ADDR VALUE
* < OK
*
* > inb ADDR
* < OK VALUE
*
* > inw ADDR
* < OK VALUE
*
* > inl ADDR
* < OK VALUE
*
* > writeb ADDR VALUE
* < OK
*
* > writew ADDR VALUE
* < OK
*
* > writel ADDR VALUE
* < OK
*
* > writeq ADDR VALUE
* < OK
*
* > readb ADDR
* < OK VALUE
*
* > readw ADDR
* < OK VALUE
*
* > readl ADDR
* < OK VALUE
*
* > readq ADDR
* < OK VALUE
*
* > read ADDR SIZE
* < OK DATA
*
* > write ADDR SIZE DATA
* < OK
*
* > b64read ADDR SIZE
* < OK B64_DATA
*
* > b64write ADDR SIZE B64_DATA
* < OK
*
* > memset ADDR SIZE VALUE
* < OK
*
* ADDR, SIZE, VALUE are all integers parsed with strtoul() with a base of 0.
* For 'memset' a zero size is permitted and does nothing.
*
* DATA is an arbitrarily long hex number prefixed with '0x'. If it's smaller
* than the expected size, the value will be zero filled at the end of the data
* sequence.
*
* B64_DATA is an arbitrarily long base64 encoded string.
* If the sizes do not match, the data will be truncated.
*
* IRQ management:
*
* > irq_intercept_in QOM-PATH
* < OK
*
* > irq_intercept_out QOM-PATH
* < OK
*
* Attach to the gpio-in (resp. gpio-out) pins exported by the device at
* QOM-PATH. When the pin is triggered, one of the following async messages
* will be printed to the qtest stream:
*
* IRQ raise NUM
* IRQ lower NUM
*
* where NUM is an IRQ number. For the PC, interrupts can be intercepted
* simply with "irq_intercept_in ioapic" (note that IRQ0 comes out with
* NUM=0 even though it is remapped to GSI 2).
*
* Setting interrupt level:
*
* > set_irq_in QOM-PATH NAME NUM LEVEL
* < OK
*
* where NAME is the name of the irq/gpio list, NUM is an IRQ number and
* LEVEL is an signed integer IRQ level.
*
* Forcibly set the given interrupt pin to the given level.
*
