c58b535f83 qemu.py: cleanup redundant calls in launch()
Now that shutdown() is guaranteed to always execute self._load_io_log()
and self._post_shutdown(), their calls in 'except' became redundant and
we can safely replace it by a call to shutdown().

17589cae90 qemu.py: use poll() instead of 'returncode'
The 'returncode' Popen attribute is not guaranteed to be updated. It
actually depends on a call to either poll(), wait() or communicate().

On the other hand, poll() will: "Check if child process has terminated.
Set and return returncode attribute."

Let's use the poll() to check whether the process is running and to get
the updated process exit code, when the process is finished.

04a963b495 qemu.py: always cleanup on shutdown()
Currently we only cleanup on shutdown() if the VM is running.

To make sure we will always cleanup, this patch makes the
self._load_io_log() and the self._post_shutdown() to
always be called on shutdown(), regardless the VM running state.

af99fa9fe2 qemu.py: better control of created files
To launch a VM, we need to create basically two files: the monitor
socket (if it's a UNIX socket) and the qemu log file.

For the qemu log file, we currently just open the path, which will
create the file if it does not exist or overwrite the file if it does
exist.

For the monitor socket, if it already exists, we are currently removing
it, even if it's not created by us.

This patch moves to _pre_launch() the responsibility to create a
temporary directory to host the files so we can remove the whole
directory on _post_shutdown().

d4e5ec877c qapi: force a UTF-8 locale for running Python
Python2 did not validate locale correctness when reading input data, so
would happily read UTF-8 data in non-UTF-8 locales. Python3 is strict so
if you try to read UTF-8 data in the C locale, it will raise an error
for any UTF-8 bytes that aren't representable in 7-bit ascii encoding.
e.g.

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 54: ordinal not in range(128)
Traceback (most recent call last):
  File "/tmp/qemu-test/src/scripts/qapi-commands.py", line 317, in <module>
    schema = QAPISchema(input_file)
  File "/tmp/qemu-test/src/scripts/qapi.py", line 1468, in __init__
    parser = QAPISchemaParser(open(fname, 'r'))
  File "/tmp/qemu-test/src/scripts/qapi.py", line 301, in __init__
    previously_included)
  File "/tmp/qemu-test/src/scripts/qapi.py", line 348, in _include
    exprs_include = QAPISchemaParser(fobj, previously_included, info)
  File "/tmp/qemu-test/src/scripts/qapi.py", line 271, in __init__
    self.src = fp.read()
  File "/usr/lib64/python3.5/encodings/ascii.py", line 26, in decode
    return codecs.ascii_decode(input, self.errors)[0]

More background on this can be seen in

  https://www.python.org/dev/peps/pep-0538/

Many distros support a new C.UTF-8 locale that is like the C locale,
but with UTF-8 instead of 7-bit ASCII. That is not entirely portable
though. This patch thus sets the LANG to "C", but overrides LC_CTYPE
to be en_US.UTF-8 locale. This gets us pretty close to C.UTF-8, but
in a way that should be portable to everywhere QEMU builds.

This patch only forces UTF-8 for QAPI scripts, since that is the one
showing the immediate error under Python3 with C locale, but potentially
we ought to force this for all python scripts used in the build process.

f7a5376d4b qapi: ensure stable sort ordering when checking QAPI entities
Some early python 3.x versions will have different default
ordering when calling the 'values()' method on a dict, compared
to python 2.x and later 3.x versions. Explicitly sort the items
to get a stable ordering.

46ec4fcea9 qapi: remove '-q' arg to diff when comparing QAPI output
When the qapi schema tests fail they merely print that the expected
output didn't match the actual output. This is largely useless when
trying diagnose what went wrong. Removing the '-q' arg to diff
means that it is still silent on successful tests, but when it
fails we'll see details of the incorrect output.

The iteritems()/itervalues() methods are gone in py3, but the
items()/values() methods are still around. The latter are less
efficient than the former in py2, but this has unmeasurably
small impact on QEMU build time, so taking portability over
efficiency is a net win.

support Python 2 and 3 in parallel.

When a 9p request is flushed (ie, cancelled) by the guest, the device
is expected to simply mark the request as used, without sending a 9p
reply (ie, without writing anything into the used buffer).

To be able to test this, we need access to the length written by the
device into the used descriptor. This patch adds a uint32_t * argument

    ui: track how much decoded data we consumed when doing SASL encoding

I attempted to fix a flaw with tracking how much data had actually been
processed when encoding with SASL. With that flaw, the VNC server could
mistakenly discard queued data that had not been sent.

The fix was not quite right though, because it merely decremented the
vs->output.offset value. This is effectively discarding data from the
end of the pending output buffer. We actually need to discard data from
the start of the pending output buffer. We also want to free memory that
is no longer required. The correct way to handle this is to use the
buffer_advance() helper method instead of directly manipulating the
offset value.

forgot to update the SDL1 frontend. Thus the SDL frontend was getting
qcodes but dispatching them as if they were qnums. IOW, keyboard input
was completely hosed with SDL1. Since the keyboard layout tables are
still all based on qnums, it is easier to just keep SDL1 using qnums as
it will be deleted in a few releases time.

2893ddd598 tests: virtio-9p: use the synth backend
The purpose of virtio-9p-test is to test the virtio-9p device, especially
the 9p server state machine. We don't really care what fsdev backend we're
using. Moreover, if we want to be able to test the flush request or a
device reset with in-flights I/O, it is close to impossible to achieve
with a physical backend because we cannot ask it reliably to put an I/O
on hold at a specific point in time.

Fortunately, we can do that with the synthetic backend, which allows to
register callbacks on read/write accesses to a specific file. This will
be used by a later patch to test the 9P flush request.

The walk request test is converted to using the synth backend.

693b21d2c7 tests: virtio-9p: move request tag to the test functions
It doesn't really makes sense to hide the request tag from the test
functions. It prevents to test the 9p server behavior when passed
a wrong tag (ie, still in use or different from P9_NOTAG for a
version request). Also the spec says that a tag is reusable as soon
as the corresponding request was replied or flushed: no need to
always increment tags like we do now. And finaly, an upcoming test
of the flush command will need to manipulate tags explicitely.

This simply changes all request functions to have a tag argument.
Except for the version request which needs P9_NOTAG, all other
tests can pass 0 since they wait for the reply before sending
another request.

fc78d5ee76 9pfs: Correctly handle cancelled requests
# Background

I was investigating spurious non-deterministic EINTR returns from
various 9p file system operations in a Linux guest served from the
qemu 9p server.

 ## EINTR, ERESTARTSYS and the linux kernel

When a signal arrives that the Linux kernel needs to deliver to user-space
while a given thread is blocked (in the 9p case waiting for a reply to its
request in 9p_client_rpc -> wait_event_interruptible), it asks whatever
driver is currently running to abort its current operation (in the 9p case
causing the submission of a TFLUSH message) and return to user space.
In these situations, the error message reported is generally ERESTARTSYS.
If the userspace processes specified SA_RESTART, this means that the
system call will get restarted upon completion of the signal handler
delivery (assuming the signal handler doesn't modify the process state
in complicated ways not relevant here). If SA_RESTART is not specified,
ERESTARTSYS gets translated to EINTR and user space is expected to handle
the restart itself.

 ## The 9p TFLUSH command

The 9p TFLUSH commands requests that the server abort an ongoing operation.
The man page [1] specifies:

```
If it recognizes oldtag as the tag of a pending transaction, it should
abort any pending response and discard that tag.
[...]
When the client sends a Tflush, it must wait to receive the corresponding
Rflush before reusing oldtag for subsequent messages. If a response to the
flushed request is received before the Rflush, the client must honor the
response as if it had not been flushed, since the completed request may
signify a state change in the server
```

In particular, this means that the server must not send a reply with the
orignal tag in response to the cancellation request, because the client is
obligated to interpret such a reply as a coincidental reply to the original
request.

 # The bug

When qemu receives a TFlush request, it sets the `cancelled` flag on the
relevant pdu. This flag is periodically checked, e.g. in
`v9fs_co_name_to_path`, and if set, the operation is aborted and the error
is set to EINTR. However, the server then violates the spec, by returning
to the client an Rerror response, rather than discarding the message
entirely. As a result, the client is required to assume that said Rerror
response is a result of the original request, not a result of the
cancellation and thus passes the EINTR error back to user space.
This is not the worst thing it could do, however as discussed above, the
correct error code would have been ERESTARTSYS, such that user space
programs with SA_RESTART set get correctly restarted upon completion of
the signal handler.
Instead, such programs get spurious EINTR results that they were not
expecting to handle.

It should be noted that there are plenty of user space programs that do not
set SA_RESTART and do not correctly handle EINTR either. However, that is
then a userspace bug. It should also be noted that this bug has been
mitigated by a recent commit to the Linux kernel [2], which essentially
prevents the kernel from sending Tflush requests unless the process is about
to die (in which case the process likely doesn't care about the response).
Nevertheless, for older kernels and to comply with the spec, I believe this
change is beneficial.

 # Implementation

The fix is fairly simple, just skipping notification of a reply if
the pdu was previously cancelled. We do however, also notify the transport
layer that we're doing this, so it can clean up any resources it may be
holding. I also added a new trace event to distinguish
operations that caused an error reply from those that were cancelled.

One complication is that we only omit sending the message on EINTR errors in
order to avoid confusing the rest of the code (which may assume that a
client knows about a fid if it sucessfully passed it off to pud_complete
without checking for cancellation status). This does mean that if the server
acts upon the cancellation flag, it always needs to set err to EINTR. I
believe this is true of the current code.

fe0a69cca5 target/hppa: Fix 32-bit operand masks for 0E FCVT
We masked the wrong bits, which prevented some of the
32-bit R registers.  E.g. "fcnvxf,sgl,sgl fr22R,fr6R".

a72bd606ca hw/hppa: Implement DINO system board
Now that we have the prerequisites in target/hppa/,
implement the hardware for a PA7100LC.

This also enables build for hppa-softmmu.

[rth: Since it is all new code, squashed all branch development
withing hw/hppa/ to a single patch.]
