Meador Inge cdb432b202 gdbserver: Don't send a GDB syscall until the system CPU is stopped
Fix an issue where the GDB server implementation was sending GDB syscall
requests while the system CPU was still running.  Syscall requests must
be sent while the CPU is stopped otherwise replies from the GDB client
might get dropped and the GDB server might be incorrectly transitioned
into a 'RUN_STATE_PAUSED' state.

Michael Tokarev 3179d694a8 Support utf8 chars in pod docs
We've at least one UTF8 char in the qemu texi doc:

 $ grep Tibor qemu-doc.texi
 by Tibor "TS" Schütz.
 $ man ./qemu.1 | grep Tibor
        by Tibor "TS" SchA~Xtz.

This patch allows utf8 in man/pod docs.

Initially it was split into two parts and sent on 2012-02-02.
Resending it again (3rd time) now in merged form.  If any
other generalizations of $(POD2MAN) are needed it can be done
in a separate patch.  Current form of $(POD2MAN) is choosen
to be able to easily change it if some implementation does
not support utf8 or resulting output has issues with local
man(1) program/macros.

First, add @documentencoding in scripts/texi2pod.pl:

Currently our texi2pod ignores @documentencoding even if it is set
properly in *.texi files.  This results in a mojibake in documents
generated from qemu.pod (which is generated from qemu-doc.texi by
texi2pod), because the rest of the tools assumes ASCII encoding.

This patch recognizes first @documentencoding in input and places
it at the beginning of output as =encoding directive.

Second, run pod2man with --utf8 option to enable utf8 in manpages:

This option makes no difference for manpages which contains only
ascii chars.  But for manpages with actual UTF8 characters (qemu
docs contains these), this change allows to see real characters
instead of mojibakes or substitutes.

Gerd Hoffmann 08c4ea294f fix screendump
Commit 45efb16124 optimized a bit too
much.  We can skip the vga_invalidate_display() in case no console
switch happened because we don't need a full redraw then.  We can *not*
skip vga_hw_update() though, because the screen content will be stale
then in case nobody else calls vga_hw_update().

Trigger: vga textmode with vnc display and no client connected.

addr, mapcache will look into the list of range of address that have been moved
(physmap/set_memory). There is currently one memory space like this, the vram,
"moved" from were it's allocated to were the guest will look into.

- rename save_devices to save-devices-state.

Changes in v6:

- remove the is_ram parameter from register_savevm_live and sets is_ram

- fix CODING_STYLE;

Paolo Bonzini fd9307912d scsi: copy serial number into VPD page 0x83
Currently QEMU passes the qdev device id to the guest in an ASCII-string
designator in page 0x83.  While this is fine, it does not match what
real hardware does; usually the ASCII-string designator there hosts
another copy of the serial number (there can be other designators,
for example with a world-wide name).  Do the same for QEMU SCSI
disks.

ATAPI does not support VPD pages, so it does not matter there.

Paolo Bonzini 9bcaf4fe26 scsi-cd: check ready condition before processing several commands
This commit is more or less obvious.  What it caused is less obvious:
SCSI CD drives failed to eject under Linux, though for example the
"change" command worked okay.  This happens because of the autoclose
option in the Linux CD-ROM driver.

The actual chain of events is quite complex and somehow involves
udev helpers; the actual command that matters is READ TOC, though
honestly it's not really clear to me how because it should always be
invoked after autoclose, not before.

Commit 1b71f7c14f moved MODULE_INIT_QOM to
way before MODULE_INIT_MACHINE, thereby breaking assumptions made in
spice-core.c which registered both a type initializer and a machine
intializer.

This fix removes the type registration, and replaces it with calling
qemu_spice_init in vl.c after command line parsing (second pass) is
done, and after timers are armed, required by spice server.

This patch fixes warnings reported by splint:

For variables which are packed in a single bit, a signed data type
like 'int' does not make much sense.

There is no obvious reason why the two values should be packed,
so I removed the packing and changed the data type to bool
because both are used as boolean values.

v2:

Some versions of gcc complain after this modification,
for example gcc (Debian 4.4.5-8) 4.4.5):

ui/vnc-auth-sasl.c: In function ‘vnc_sasl_client_cleanup’:
ui/vnc-auth-sasl.c:34: error: suggest parentheses around assignment used as truth value

Obviously, the compiler does not like code which does
bool = unsigned = bool = 0
