The TARGET_HAS_ICE #define is intended to indicate whether a target-*
guest CPU implementation supports the breakpoint handling. However,
all our guest CPUs have that support (the only two which do not
define TARGET_HAS_ICE are unicore32 and openrisc, and in both those
cases the bp support is present and the lack of the #define is just
a bug). So remove the #define entirely: all new guest CPU support
should include breakpoint handling as part of the basic implementation.

Add API to allocate "resizeable" RAM.
This looks just like regular RAM generally, but
has a special property that only a portion of it
(used_length) is actually used, and migrated.
This used_length size can change across reboots.
Follow up patches will change used_length for such blocks at migration,
making it easier to extend devices using such RAM (notably ACPI,
but in the future thinkably other ROMs) without breaking migration
compatibility or wasting ROM (guest) memory.
Device is notified on resize, so it can adjust if necessary.
qemu_ram_alloc_resizeable allocates this memory, qemu_ram_resize resizes
it.
Note: nothing prevents making all RAM resizeable in this way.
However, reviewers felt that only enabling this selectively will
make some class of errors easier to detect.

This patch allows us to distinguish between two
length values for each block:
max_length - length of memory block that was allocated
used_length - length of block used by QEMU/guest
Currently, we set used_length - max_length, unconditionally.
Follow-up patches allow used_length <= max_length.

In QEMU 2.2 the exception_index value was added to the migration stream
through a subsection. The default was set to 0, which is wrong and
should have been -1.
However, 2.2 does not have commit e511b4d (cpu-exec: reset exception_index
correctly, 2014-11-26), hence in 2.2 the exception_index is never used
and is set to -1 on the next call to cpu_exec. So we can change the
migration stream to make the default -1. The effects are:
- 2.2.1 -> 2.2.0: cpu->exception_index set incorrectly to 0 if it
were -1 on the source; then reset to -1 in cpu_exec. This is TCG
only; KVM does not use exception_index.
- 2.2.0 -> 2.2.1: cpu->exception_index set incorrectly to -1 if it
were 0 on the source; but it would be reset to -1 in cpu_exec anyway.
This is TCG only; KVM does not use exception_index.
- 2.2.1 -> 2.1: two bugs fixed: 1) can migrate backwards if
cpu->exception_index is set to -1; 2) should not migrate backwards
(but 2.2.0 allows it) if cpu->exception_index is set to 0
- 2.2.0 -> 2.3.0: 2.2.0 will send the subsection unnecessarily if
exception_index is -1, but that is not a problem. 2.3.0 will set
cpu->exception_index to -1 if it is 0 on the source, but this would
be anyway a problem for 2.2.0 -> 2.2.x migration (due to lack of
commit e511b4d in 2.2.x) so we can ignore it
- 2.2.1 -> 2.3.0: everything works.
In addition, play it safe and never send the subsection unless TCG
is in use. KVM does not use exception_index (PPC KVM stores values
in it for use in the subsequent call to ppc_cpu_do_interrupt, but
does not need it as soon as kvm_handle_debug returns). Xen and
qtest do not run any code for the CPU at all.

The code in invalidate_and_set_dirty() needs to handle addr/length
combinations which cross guest physical page boundaries. This can happen,
for example, when disk I/O reads large blocks into guest RAM which previously
held code that we have cached translations for. Unfortunately we were only
checking the clean/dirty status of the first page in the range, and then
were calling a tb_invalidate function which only handles ranges that don't
cross page boundaries. Fix the function to deal with multipage ranges.
The symptoms of this bug were that guest code would misbehave (eg segfault),
in particular after a guest reboot but potentially any time the guest
reused a page of its physical RAM for new code.

Devices that use address_space_rw to write large areas to memory
(as opposed to address_space_map/unmap) were broken with respect
to migration since fe680d0 (exec: Limit translation limiting in
address_space_translate to xen, 2014-05-07). Such devices include
IDE CD-ROMs.
The reason is that invalidate_and_set_dirty (called by address_space_rw
but not address_space_map/unmap) was only setting the dirty bit for
the first page in the translation.
To fix this, introduce cpu_physical_memory_set_dirty_range_nocode that
is the same as cpu_physical_memory_set_dirty_range except it does not
muck with the DIRTY_MEMORY_CODE bitmap. This function can be used if
the caller invalidates translations with tb_invalidate_phys_page_range.
There is another difference between cpu_physical_memory_set_dirty_range
and cpu_physical_memory_set_dirty_flag; the former includes a call
to xen_modified_memory. This is handled separately in
invalidate_and_set_dirty, and is not needed in other callers of
cpu_physical_memory_set_dirty_range_nocode, so leave it alone.
Just one nit: now that invalidate_and_set_dirty takes care of handling
multiple pages, there is no need for address_space_unmap to wrap it
in a loop. In fact that loop would now be O(n^2).

Old code was affected by memory gaps which resulted in buffer pointers
pointing to address outside of the mapped regions.
Here we are introducing following changes:
- new function qemu_get_ram_block_host_ptr() returns host pointer
to the ram block, it is needed to calculate offset of specific
region in the host memory
- new field mmap_offset is added to the VhostUserMemoryRegion. It
contains offset where specific region starts in the mapped memory.
As there is stil no wider adoption of vhost-user agreement was made
that we will not bump version number due to this change
- other fileds in VhostUserMemoryRegion struct are not changed, as
they are all needed for usermode app implementation
- region data is not taken from ram_list.blocks anymore, instead we
use region data which is alredy calculated for use in vhost-net
- Now multiple regions can have same FD and user applicaton can call
mmap() multiple times with the same FD but with different offset
(user needs to take care for offset page alignment)
