  qemu: add .exrc

I've been using this to get correct indenting with vim
in qemu for a while, but it's a bit easier if we
put the settings in the central place.
Note that
1. you still need to enable 'exrc' and 'secure'
   options in your vimrc for these settings to take effect.
2. you can create a .vimrc file if 'exrc' is on but there's
   need to bypass this configuration.

  pcie: drop version_id field for live migration

While testing q35 live migration, I found that the migration would abort with
the following error: "Unknown savevm section type 76".

The error is due to this check failing in 'vmstate_load_state()':

    while(field->name) {
  if ((field->field_exists &&
       field->field_exists(opaque, version_id)) ||
      (!field->field_exists &&
       field->version_id <= version_id)) {

The VMSTATE_PCIE_DEVICE() currently has a 'version_id' set to 2. However,
'version_id' in the above check is 1. And thus we fail to load the pcie device
field. Further the code returns to 'qemu_loadvm_state()' which produces the
error that I saw.

I'm proposing to fix this by simply dropping the 'version_id' field from
VMSTATE_PCIE_DEVICE(). VMSTATE_PCI_DEVICE() defines no such field and further
the vmstate_pcie_device that VMSTATE_PCI_DEVICE() refers to is already
versioned. Thus, any versioning issues could be detected at the vmsd level.

Taking a step back, I think that the 'field->version_id' should be compared
against a saved version number for the field not the 'version_id'. Futhermore,
once vmstate_load_state() is called recursively on another vmsd, the check of:

    if (version_id > vmsd->version_id) {
  return -EINVAL;
    }

Will never fail since version_id is always equal to vmsd->version_id. So I'm
wondering why we aren't storing the vmsd version id of the source in the
migration stream?

This patch also renames the 'name' field of vmstate_pcie_device from:
PCIDevice -> PCIEDevice to differentiate it from vmstate_pci_device.

  pcie_aer: clear cmask for Advanced Error Interrupt Message Number

The Advanced Error Interrupt Message Number (bits 31:27 of the Root
Error Status Register) is updated when the number of msi messages assigned to a
device changes. Migration of windows 7 on q35 chipset failed because the check
in get_pci_config_device() fails due to cmask being set on these bits. Its valid
to update these bits and we must restore this state across migration.

Also update net/[socket,tap].c consumers to use the new prefix.

  qemu: Use valgrind annotations to mark kvm guest memory as defined

valgrind with kvm produces a big amount of false positives regarding
"Conditional jump or move depends on uninitialised value(s)". This
happens because the guest memory is allocated with qemu_vmalloc which
boils down posix_memalign etc. This function is (correctly) considered
by valgrind as returning undefined memory.

Since valgrind is based on jitting code, it will not be able to see
changes made by the guest to guest memory if this is done by KVM_RUN,
thus keeping most of the guest memory undefined.

Now lots of places in qemu will then use guest memory to change behaviour.
To avoid the flood of these messages, lets declare the whole guest
memory as defined. This will reduce the noise and allows us to see real
problems.

In the future we might want to make this conditional, since there
is actually something that we can use those false positives for:
These messages will point to code that depends on guest memory, so
we can use these backtraces to actually make an audit that is focussed
only at those code places. For normal development we dont want to
see those messages, though.

  kvm: i386: Add classic PCI device assignment

This adds PCI device assignment for i386 targets using the classic KVM
interfaces. This version is 100% identical to what is being maintained
in qemu-kvm for several years and is supported by libvirt as well. It is
expected to remain relevant for another couple of years until kernels
without full-features and performance-wise equivalent VFIO support are
obsolete.

A refactoring to-do that should be done in-tree is to model MSI and
MSI-X support via the generic PCI layer, similar to what VFIO is already
doing for MSI-X. This should improve the correctness and clean up the
code from duplicate logic.

  use --libexecdir instead of ignoring it first and reinventing it later

Commit 7b93fadf3a38d1ed65ea5536a52efc2772c6e3b8 "Add basic version
of bridge helper" put the bridge helper executable into a fixed
${prefix}/libexec/ location, instead of using ${libexecdir} for
this.  At the same time, --libexecdir is being happily ignored
by ./configure.  Even more, the same patch sets unused $libexecdir
variable in the generated config-host.mak, and uses fixed string
(\${prefix}/libexecdir) for the bridge helper binary.

Fix this braindamage by introducing $libexecdir variable, using
it for the bridge helper binary, and recognizing --libexecdir.

This patch is applicable to stable-1.1.

  RTC: Update the RTC clock only when reading it

Calculate guest RTC based on the time of the last update, instead of
using timers.  The formula is

    (base_rtc + guest_time_now - guest_time_last_update + offset)

Base_rtc is the RTC value when the RTC was last updated.
Guest_time_now is the guest time when the access happens.
Guest_time_last_update was the guest time when the RTC was last updated.
Offset is used when divider reset happens or the set bit is toggled.

The timer is kept in order to signal interrupts, but it only needs to
run when either UF or AF is cleared.  When the bits are both set, the
timer does not run.

UIP is now synthesized when reading register A.  If the timer is not set,
or if there is more than one second before it (as is the case at the
end of this series), the leading edge of UIP is computed and the rising
edge occurs 220us later.  If the update timer occurs within one second,
however, the rising edge of the AF and UF bits should coincide withe
the falling edge of UIP.  We do not know exactly when this will happen
because there could be delays in the servicing of the timer.  Hence, in
this case reading register A only computes for the rising edge of UIP,
and latches the bit until the timer is fired and clears it.

  RTC: Do not fire timer periodically to catch next alarm

This patch limits further the usage of a periodic timer.  It computes the
time of the next alarm, and uses it to skip all intermediate occurrences
of the timer.

  RTC: Get and set time without going through s->current_tm

This patch makes rtc_set_time and rtc_set_cmos work without reading
s->current_tm.  In the case of rtc_set_time I introduce a new
function that retrieves the time and stores into a given struct tm
(not hard-coded to s->current_tm).  In the case of rtc_set_cmos, the
current time is similarly taken from a struct tm rather than
s->current_tm.

  Add ability to disable build of all targets

Allow passing of '--target-list=' to configure to request that
all targets are to be disabled. This allows for doing a very
fast tools-only build of things like qemu-img, qemu-io, qemu-nbd.

  Log Message:
  -----------
  Add ability to force enable/disable of tools build

The qemu-img, qemu-nbd and qemu-io tools are built conditionally
based on whether any softmmu target is enabled. These are useful
self-contained tools which can be used in many other scenarios.
Add new --enable-tools/--disable-tools args to configure to allow
the user to explicitly turn on / off their build. The default
behaviour is now to build these tools are all times, regardless
of whether any softmmu target is enabled
