test-qga: Actually test 0xff sync bytes Commit 62c39b3 introduced test-qga, and at face value, appears to be testing the 'guest-sync' behavior that is recommended for guests in sending 0xff to QGA to force the parser to reset. But this aspect of the test has never actually done anything: the qmp_fd() call chain converts its string argument into QObject, then converts that QObject back to the actual string that is sent over the wire - and the conversion process silently drops the 0xff byte from the string sent to QGA, thus never resetting the QGA parser. An upcoming patch will get rid of the wasteful round trip through QObject, at which point the string in test-qga will be directly sent over the wire. But fixing qmp_fd() to actually send 0xff over the wire is not all we have to do - the actual QMP parser loudly complains that 0xff is not valid JSON, and sends an error message _prior_ to actually parsing the 'guest-sync' or 'guest-sync-delimited' command. With 'guest-sync', we cannot easily tell if this error message is a result of our command - which is WHY we invented the 'guest-sync-delimited' command. So for the testsuite, fix things to only check 0xff behavior on 'guest-sync-delimited', and to loop until we've consumed all garbage prior to the requested delimiter, which is compatible with the documented actions that a real QGA client is supposed to do. Ideally, we'd fix the QGA JSON parser to silently ignore 0xff rather than sending an error message back, at which point we could enhance this test for 'guest-sync' as well as for 'guest-sync-delimited'. But for the sake of this patch, our testing of 'guest-sync' is no worse than it was pre-patch, because we have never been sending 0xff over the wire in the first place.
