This is the same fix that was recently applied to info mem. Before
this change, info tlb output looked like:
ffffffffffffc000: 000000000fffc000 --------W
ffffffffffffd000: 000000000fffd000 --------W
ffffffffffffe000: 000000000fffe000 --------W
fffffffffffff000: 000000000ffff000 --------W
With this change, it looks like
00000000ffffc000: 000000000fffc000 --------W
00000000ffffd000: 000000000fffd000 --------W
00000000ffffe000: 000000000fffe000 --------W
00000000fffff000: 000000000ffff000 --------W

Previously, "info mem" considered and displayed only the last-level
protection bits for a memory range, which doesn't accurrately
represent the protection of that range. Now it shows the combined
protection.

Previously, on 32-bit i386, info mem used signed 32-bit int's to store
the page table indexes. As a result, address calculation was done in
32 bits and then incorrectly sign-extended to 64 bits, yielding output
like
ffffffffef000000-ffffffffef031000 0000000000031000 ur-
ffffffffef7bc000-ffffffffef7bd000 0000000000001000 urw
ffffffffef7bd000-ffffffffef7be000 0000000000001000 ur-
This makes these indexes unsigned, which yields correct output
00000000ef000000-00000000ef031000 0000000000031000 ur-
00000000ef7bc000-00000000ef7bd000 0000000000001000 urw

Allow client connections for VNC and socket based character
devices to be passed in over the monitor using SCM_RIGHTS.
One intended usage scenario is to start QEMU with VNC on a
UNIX domain socket. An unprivileged user which cannot access
the UNIX domain socket, can then connect to QEMU's VNC server
by passing an open FD to libvirt, which passes it onto QEMU.
{ "execute": "get_fd", "arguments": { "fdname": "myclient" } }
{ "return": {} }
{ "execute": "add_client", "arguments": { "protocol": "vnc",
"fdname": "myclient",
"skipauth": true } }
{ "return": {} }
In this case 'protocol' can be 'vnc' or 'spice', or the name
of a character device (eg from -chardev id=XXXX)
The 'skipauth' parameter can be used to skip any configured
VNC authentication scheme, which is useful if the mgmt layer
talking to the monitor has already authenticated the client
in another way.

* monitor.c: Implement 'client_add' command
* qemu-char.c, qemu-char.h: Add 'qemu_char_add_client' method

This **CHANGES** the human monitor "nmi" command behavior.
Currently it accepts an CPU argument which, when provided, will send
the NMI to the specified CPU. This feature is of discussable value
though and HMP shouldn't have more features than QMP, so let's use
QMP's instead (it's also simpler).

Using cpu_physical_memory_read, cpu_physical_memory_write and ldub_phys
improves readability and allows removing some type casts.
lduw_phys and ldl_phys were not used because both require aligned
addresses. Therefore it is not possible to simply replace existing
calls by one of these functions.

On ppc machines with hash table MMUs, the special purpose register SDR1
contains both the base address of the encoded size (hashed) page tables.
At present, we interpret the SDR1 value within the address translation
path. But because the encodings of the size for 32-bit and 64-bit are
different this makes for a confusing branch on the MMU type with a bunch
of curly shifts and masks in the middle of the translate path.
This patch cleans things up by moving the interpretation on SDR1 into the
helper function handling the write to the register. This leaves a simple
pre-sanitized base address and mask for the hash table in the CPUState
structure which is easier to work with in the translation path.
This makes the translation path more readable. It addresses the FIXME
comment currently in the mtsdr1 helper, by validating the SDR1 value during
interpretation. Finally it opens the way for emulating a pSeries-style
partition where the hash table used for translation is not mapped into
the guests's RAM.

This was done with:
sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \
$(git grep -l 'qemu_get_clock\>' )
sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \
$(git grep -l 'qemu_new_timer\>' )
after checking that get_clock and new_timer never occur twice
on the same line. There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.
There was exactly one false positive in qemu_run_timers:
- current_time = qemu_get_clock (clock);
+ current_time = qemu_get_clock_ns (clock);
which is of course not in this patch.

commit 52c18be9e99dabe295321153fda7fce9f76647ac introduced a regression in the
change vnc password command that changed the behavior of setting the VNC
password to an empty string from disabling login to disabling authentication.
This commit refactors the code to eliminate this overloaded semantics in
vnc_display_password and instead introduces the vnc_display_disable_login. The
monitor implementation then determines the behavior of an empty or missing
string.
Recently, a set_password command was added that allows both the Spice and VNC
password to be set. This command has not shown up in a release yet so the
behavior is not yet defined.
This patch proposes that an empty password be treated as an empty password with
no special handling. For specifically disabling login, I believe a new command
should be introduced instead of overloading semantics.
I'm not sure how Spice handles this but I would recommend that we have Spice
and VNC have consistent semantics here for the 0.14.0 release.

Handle spice client migration, i.e. inform a spice client connected
about the new host and connection parameters, so it can move over the
connection automatically.
The monitor command has a not-yet used protocol argument simliar to
set_password and expire_password commands. This allows to add a simliar
feature to vnc in the future. Daniel Berrange plans to work on this.

When the following test case is injected with mce command, maybe user could not
get the expected result.
DATA
command cpu bank status mcg_status addr misc
(qemu) mce 1 1 0xbd00000000000000 0x05 0x1234 0x8c
Expected Result
panic type: "Fatal Machine check"
That is because each mce command can only inject the given cpu and could not
inject mce interrupt to other cpus. So user will get the following result:
panic type: "Fatal machine check on current CPU"
"broadcast" option is used for injecting dummy data into other cpus. Injecting
mce with this option the expected result could be gotten.
Usage:
Broadcast[on]
command broadcast cpu bank status mcg_status addr misc
(qemu) mce -b 1 1 0xbd00000000000000 0x05 0x1234 0x8c
Broadcast[off]

reasons:
1. this function is now called only by QMP code, so testing if
