Existing qmp() callers do not expect a response object.  In order to
implement real QMP test cases it will be necessary to inspect the
response object.

Rename qmp() to qmp_discard_response().  Later patches will introduce a
qmp() function that returns the response object and tests that use it.

Do not always set FD_SR0_SEEK, as callers already set it if needed.

Readability of the test code has suffered as the test case evolved. This

Calling sense interrupt status while there is no interrupt should
return invalid command (0x80).

If you try to read from a floppy drive without a media, you should get
an abnormal termination error.

As default a guest has always one floppy drive so 0x10 byte in CMOS
has to have 0x40 value. Higher 4 bits means that the first floppy drive
is 1.44 Mb 3"5 drive and lower 4 bits means the second drive is not present.

After the guest starts DSKCHG bit in DIR register should be set. If there
is no media in drive, this bit should be set all the time.

Because we start the guest without media in drive, we have to swap
'eject' and 'change' in 'test_media_change'.
