The NetReceive prototype gets a const buffer:
typedef ssize_t (NetReceive)(NetClientState *, const uint8_t *, size_t);
We already have the address_space_write() method to write a const
buffer to an address space. Use it to avoid:
hw/net/i82596.c: In function ‘i82596_receive’:
hw/net/i82596.c:644:54: error: passing argument 4 of ‘address_space_rw’ discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers]

v4: Drop parenthesis when removing cast (Eric Blake)
POSIX requires $PWD to be reliable, and we expect all
shells used by qemu scripts to be relatively close to
POSIX. Thus, it is smarter to avoid forking the pwd
executable for something that is already available in
the environment.
So replace it with the following:
sed -i 's/\(`pwd`\|\$(pwd)\)/$PWD/g' $(git grep -l pwd)
Then delete a pointless line assigning PWD to itself.

Add a new Coccinelle script which replaces uses of the inplace
byteswapping functions *_to_cpus() and cpu_to_*s() with their
not-in-place equivalents. This is useful for where the swapping
is done on members of a packed struct -- taking the address
of the member to pass it to an inplace function is undefined
behaviour in C.

Now that we can safely call QOBJECT() on QObject * as well as its
subtypes, we can have macros qobject_ref() / qobject_unref() that work
everywhere instead of having to use QINCREF() / QDECREF() for QObject
and qobject_incref() / qobject_decref() for its subtypes.
The replacement is mechanical, except I broke a long line, and added a
cast in monitor_qmp_cleanup_req_queue_locked(). Unlike
qobject_decref(), qobject_unref() doesn't accept void *.
Note that the new macros evaluate their argument exactly once, thus no
need to shout them.

cpu_restore_state officially supports being passed an address it can't
resolve the state for. As a result the checks in the helpers are
superfluous and can be removed. This makes the code consistent with
other users of cpu_restore_state.
Of course this does nothing to address what to do if cpu_restore_state
can't resolve the state but so far it seems this is handled elsewhere.
The change was made with included coccinelle script.

We have macros in place to make it less verbose to add a subtype
of QObject to both QDict and QList. While we have made cleanups
like this in the past (see commit fcfcd8ffc, for example), having
it be automated by Coccinelle makes it easier to maintain.
The script is separate from the cleanups, for ease of review and
backporting. A later patch will then add further possible cleanups.
