The old code aborted configure when no emulation target was selected.
Even after removing the 'exit 1', it tried to read from STDIN
when QEMU was configured with
configure' '--disable-user' '--disable-system'
This is fixed here.

This patch adds a "use64" property which will make the ivshmem driver
register a 64bit memory bar when set, so you have something to play with
when testing 64bit pci bits. It also allows to have quite big shared
memory regions, like this:
[root@fedora ~]# lspci -vs1:1
01:01.0 RAM memory: Red Hat, Inc Device 1110
Subsystem: Red Hat, Inc Device 1100
Physical Slot: 1-1
Flags: fast devsel
Memory at fd400000 (32-bit, non-prefetchable) [disabled] [size=256]
Memory at 8040000000 (64-bit, prefetchable) [size=1G]
[ v5: rebase, update compat property for post-1.2 merge ]
[ v4: rebase & adapt to latest master again ]
[ v3: rebase & adapt to latest master ]
[ v2: default to on as suggested by avi,
turn off for pc-$old using compat property ]

Like the C assert macro, except only enabled for CONFIG_DEBUG_TCG,
and without having to set _NDEBUG and disable all other asserts at
the same time.
The use of __builtin_unreachable (when available) gives the compiler
the same information, which may (or may not) help it optimize better.

For tcg_gen_concat_i32_i64 we only use deposit if the host supports it.
For tcg_gen_concat32_i64 even if the host does not, as we get identical

This is derived from the Supriya Kannery's reopen patches.
This contains the raw-posix driver changes for the bdrv_reopen_*
functions. All changes are staged into a temporary scratch buffer
during the prepare() stage, and copied over to the live structure
during commit(). Upon abort(), all changes are abandoned, and the
live structures are unmodified.
The _prepare() will create an extra fd - either by means of a dup,
if possible, or opening a new fd if not (for instance, access
control changes). Upon _commit(), the original fd is closed and
the new fd is used. Upon _abort(), the duplicate/new fd is closed.

This is based on Supriya Kannery's bdrv_reopen() patch series.
This provides a transactional method to reopen multiple
images files safely.
Image files are queue for reopen via bdrv_reopen_queue(), and the
reopen occurs when bdrv_reopen_multiple() is called. Changes are
staged in bdrv_reopen_prepare() and in the equivalent driver level
functions. If any of the staged images fails a prepare, then all
of the images left untouched, and the staged changes for each image
abandoned.
Block drivers are passed a reopen state structure, that contains:
* BDS to reopen
* flags for the reopen
* opaque pointer for any driver-specific data that needs to be
persistent from _prepare to _commit/_abort
* reopen queue pointer, if the driver needs to queue additional
BDS for a reopen

bdrv_set_enable_write_cache() sets the bs->enable_write_cache flag,
but without the flag recorded in bs->open_flags, then next time
a reopen() is performed the enable_write_cache setting may be
inadvertently lost.
This will set the flag in open_flags, so it is preserved across
reopens.

I believe the bs->keep_read_only flag is supposed to reflect
the initial open state of the device. If the device is initially
opened R/O, then commit operations, or reopen operations changing
to R/W, are prohibited.
Currently, the keep_read_only flag is only accurate for the active
layer, and its backing file. Subsequent images end up always having
the keep_read_only flag set.
For instance, what happens now:
[ base ] kro = 1, ro = 1
|
v
[ snap-1 ] kro = 1, ro = 1
|
v
[ snap-2 ] kro = 0, ro = 1
|
v
[ active ] kro = 0, ro = 0
What we want:
[ base ] kro = 0, ro = 1
|
v
[ snap-1 ] kro = 0, ro = 1
|
v
[ snap-2 ] kro = 0, ro = 1
|
v
[ active ] kro = 0, ro = 0

If readonly=on is given at device creation time, the ->readonly flag
needs to be set in the block driver state for this device so that
readonly-ness is preserved across media changes (qmp change command).
Similarly, to preserve the snapshot property requires ->open_flags to
be correct.

GLib 2.0 include files use __printf__ for the format attribute
which resolves to native format strings on w32 hosts.
QEMU wants standard format strings instead of native format
strings, so we simply change any declaration with __printf__
to use __gnu_printf__.
This works because all basic printf functions support both
kinds of format strings.
This fixes a compiler warning:
qapi/string-output-visitor.c: In function ‘print_type_int’:
qapi/string-output-visitor.c:34:5: warning: unknown conversion type character ‘l’ in format [-Wformat]
