qapi-gen: New common driver for code and doc generators
Whenever qapi-schema.json changes, we run six programs eleven times to
update eleven files. Similar for qga/qapi-schema.json. This is
silly. Replace the six programs by a single program that spits out
all eleven files.
The programs become modules in new Python package qapi, along with the
helper library. This requires moving them to scripts/qapi/. While
moving them, consistently drop executable mode bits.

qapi: Turn generators into modules
The next commit will introduce a common driver program for all
generators. The generators need to be modules for that. qapi2texi.py
already is. Make the other generators follow suit.
The changes are actually trivial. Obvious in the diffs once you view
them with whitespace changes ignored.

qapi: New classes QAPIGenC, QAPIGenH, QAPIGenDoc
These classes encapsulate accumulating and writing output.
Convert C code generation to QAPIGenC and QAPIGenH. The conversion is
rather shallow: most of the output accumulation is not converted.
Left for later.
The indentation machinery uses a single global variable indent_level,
even though we generally interleave creation of a .c and its .h. It
should become instance variable of QAPIGenC. Also left for later.
Documentation generation isn't converted, and QAPIGenDoc isn't used.

* it can only handle splitting a line into two
* it unavoidably leaks memory, so it can't be used

nbd: Honor server's advertised minimum block size
Commit
79ba8c98 (v2.7) changed the setting of request_alignment
to occur only during bdrv_refresh_limits(), rather than at at
bdrv_open() time; but at the time, NBD was unaffected, because
it still used sector-based callbacks, so the block layer
defaulted NBD to use 512 request_alignment.
Later, commit
70c4fb26 (also v2.7) changed NBD to use byte-based
callbacks, without setting request_alignment. This resulted in
NBD using request_alignment of 1, which works great when the
server supports it (as is the case for qemu-nbd), but falls apart
miserably if the server requires alignment (but only if qemu
actually sends a sub-sector request; qemu-io can do it, but
most qemu operations still perform on sectors or larger).
Even later, the NBD protocol was updated to document that clients
should learn the server's minimum alignment during NBD_OPT_GO;
and recommended that clients should assume a minimum size of 512
unless the server understands NBD_OPT_GO and replied with a smaller
size. Commit
081dd1fe (v2.10) attempted to do that, by assigning
request_alignment to whatever was learned from the server; but
it has two flaws: the assignment is done during bdrv_open() so
it gets unconditionally wiped out back to 1 during any later
bdrv_refresh_limits(); and the code is not using a default of 512
when the server did not report a minimum size.
Fix these issues by moving the assignment to request_alignment
to the right function, and by using a sane default when the
server does not advertise a minimum size.

In our Armv8a server, we try to configure the vhost scsi but fail
to boot up the guest (-machine virt-2.10). The guest's boot failure
is very early, even earlier than grub.
There are 3 virtqueues (ctrl, event and cmd) for virtio scsi device,
but ovmf and seabios will only set the physical address for the 3rd
one (cmd). Then in vhost_virtqueue_start(), virtio_queue_get_desc_addr
will be 0 for ctrl and event vq when qemu negotiates with ovmf. So
vhost_memory_map fails with ENOMEM.
This patch just fixs it by early quitting the virtqueue start/stop
when virtio_queue_get_desc_addr is 0.
Btw, after guest kernel starts, all the 3 queues will be initialized
and set address correctly.

s390x/tcg: fix loading 31bit PSWs with the highest bit set
Let's also put the 31-bit hack in front of the REAL MMU, otherwise right
now we get errors when loading a PSW where the highest bit is set (e.g.
via s390-netboot.img). The highest bit is not masked away, therefore we
inject addressing exceptions into the guest.
The proper fix will later be to do all address wrapping before accessing
the MMU - so we won't get any "wrong" entries in there (which makes
flushing also easier). But that will require more work (wrapping in
load_psw, wrapping when incrementing the PC, wrapping every memory
access).
This fixes the tests/pxe-test test.
