  kvm: Reallocate dirty_bmap when we change a slot

kvm_set_phys_mem can be called to reallocate a slot by something the
guest does (e.g. writing to PAM and other chipset registers).
This can happen in the middle of a migration, and if we're unlucky
it can now happen between the split 'sync' and 'clear'; the clear
asserts if there's no bmap to clear.   Recreate the bmap whenever
we change the slot, keeping the clear path happy.

Typically this is triggered by the guest rebooting during a migrate.

  vl: move icount configuration earlier

Once qemu_tcg_configure is turned into a QOM property setter, it will not
be able to set a default value for mttcg_enabled.  Setting the default will
move to the TCG instance_init function, which currently runs before "-icount"
is processed.

However, it is harmless to do configure_icount for all accelerators; we will
just fail later if a non-TCG accelerator is selected.  So do that.

Move everything related to mttcg_enabled in accel/tcg/tcg-all.c,
which will make even more sense when "thread" becomes a QOM property.

For now, initializing mttcg_enabled in the instance_init function
prepares for the next patch, which will only invoke qemu_tcg_configure
when the command line includes a -accel option.

  vl: merge -accel processing into configure_accelerators

The next step is to move the parsing of "-machine accel=..." into vl.c,
unifying it with the configure_accelerators() function that has just
been introduced.  This way, we will be able to desugar it into multiple
"-accel" options, without polluting accel/accel.c.

The CONFIG_TCG and CONFIG_KVM symbols are not available in vl.c, but
we can use accel_find instead to find their value at runtime.  Once we
know that the binary has one of TCG or KVM, the default accelerator
can be expressed simply as "tcg:kvm", because TCG never fails to initialize.

  vl: configure accelerators from -accel options

Drop the "accel" property from MachineState, and instead desugar
"-machine accel=" to a list of "-accel" options.

This has a semantic change due to removing merge_lists from -accel.
For example:

- "-accel kvm -accel tcg" all but ignored "-accel kvm".  This is a bugfix.

- "-accel kvm -accel thread=single" ignored "thread=single", since it
  applied the option to KVM.  Now it fails due to not specifying the
  accelerator on "-accel thread=single".

- "-accel tcg -accel thread=single" chose single-threaded TCG, while now
  it will fail due to not specifying the accelerator on "-accel
  thread=single".

Also, "-machine accel" and "-accel" become incompatible.

The first machine property to fall is Xen's Intel integrated graphics

a property on the machine object, but desugars to a GlobalProperty on
accelerator objects.

The setter is very simple, since the value ends up in a
global variable, so this patch also provides an example before the more
complicated cases that follow it.

The KVMState struct is opaque, so provide accessors for the fields
that will be moved from current_machine to the accelerator.  For now
they just forward to the machine object, but this will change.

  object: Improve documentation of interfaces

QOM interfaces allow a limited form of multiple inheritance, at the
condition of being stateless. That is, they cannot be instantiated
and a pointer to an interface shouldn't be dereferenceable in any way.
This is achieved by making the QOM instance type an incomplete type,
which is, as mentioned by Markus Armbruster, the closest you can get
to abstract class in C.

Incomplete types are widely used to hide implementation details, but
people usually expect to find at least one place where the type is
fully defined. The fact that it doesn't happen with QOM interfaces is
quite disturbing, especially since it isn't documented anywhere as
recently discussed in this thread:

https://lists.gnu.org/archive/html/qemu-devel/2019-12/msg01579.html

Amend the documentation in the object.h header file to provide more
details about why and how to implement QOM interfaces using incomplete
types.

Both gsi_handler() and kvm_pc_gsi_handler() have the same content,

The kernel-doc extension accepts a filename, which is relative to
the QEMU source tree root.  The extension also notifies Sphinx about the
document dependency on the file, causing the document to be rebuilt when
the file has been changed.

  docs: tweak kernel-doc for QEMU coding standards

Surprisingly, QEMU does have a pretty consistent doc comment style and
it is not very different from the Linux kernel's.  Of the documentation
"sigils", only "#" separates the QEMU doc comment style from Linux's,
and it has 200+ instances vs. 6 for the kernel's '&struct foo' (all in
accel/tcg/translate-all.c), so it's clear that the two standards are
different in this respect.  In addition, our structs are typedefed and
recognized by CamelCase names.

Adjust kernel-doc's parser for these two aspects of the QEMU coding
standards.  The patch has been valid, with hardly any change, for over
two years, so it should not be an issue to keep kernel-doc in sync with
the Linux copy.

Add the XEN_IGD_PASSTHROUGH Kconfig option.

Xen build has that option selected by default. Non-Xen builds now
have to select this feature manually.

  hw/i386: Remove the deprecated machines 0.12 up to 0.15

These machines can't be used reliably for migration anymore, quoting
https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg04516.html :

"
 due to the introduction of the memory API, the firmware is not
 migrated correctly from source to destination.  On QEMU <1.3 the
 0xf0000-0xfffff area is basically a copy of the higher
 0xffff0000-0xffffffff area, while on more recent versions it is
 initialized with zeroes and the firmware copies from 0xffff0000 to
 0xf0000.  When you migrate from old to new QEMU, after reboot there's
 nothing at 0xf0000 and bugs ensue.
"

The pc-0.x machines have been marked as deprecated since QEMU v4.0, so
it is time to remove them now.

And while we're at it, mark the remaining pc-1.x machine types
as deprecated now, too, so that we finally only have "pc-i440fx"
and "pc-q35" machine types left (apart from the non-versioned
"isapc" and "microvm") once we remove them in a couple of releases.

  vga: cleanup mapping of VRAM for non-PCI VGA

vga_init_vbe is now used only from ISA VGA cards.  Since the alias is
not needed anymore, remove it (effectively reverting commit 8294a64d7f,
"vga: fix vram double-mapping with -vga std and -M pc-0.12", 2012-05-29)
and the now unused vbe_mapped field of VGACommonState.  The function now
consists of a single memory_region_add_subregion call, so we can inline
it; this avoids incorrect usage from PCI cards.
