The Nios II target is deprecated since v8.2 in commit 9997771bc1
("target/nios2: Deprecate the Nios II architecture").

Remove:
- Buildsys / CI infra
- User emulation
- System emulation (10m50-ghrd & nios2-generic-nommu machines)
- Tests

dcd092a063 accel/tcg: Improve can_do_io management
We already attempted to set and clear can_do_io before the first
and last insns, but only used the initial value of max_insns and
the call to translator_io_start to find those insns.

Now that we track insn_start in DisasContextBase, and now that
we have emit_before_op, we can wait until we have finished
translation to identify the true first and last insns and emit
the sets of can_do_io at that time.

This fixes the case of a translation block which crossed a page
boundary, and for which the second page turned out to be mmio.
In this case we truncate the block, and the previous logic for
can_do_io could leave a block with a single insn with can_do_io
set to false, which would fail an assertion in cpu_io_recompile.

03bfc2188f physmem: Fix migration dirty bitmap coherency with TCG memory access
The fastpath in cpu_physical_memory_sync_dirty_bitmap() to test large
aligned ranges forgot to bring the TCG TLB up to date after clearing
some of the dirty memory bitmap bits. This can result in stores though
the TCG TLB not setting the dirty memory bitmap and ultimately causes
memory corruption / lost updates during migration from a TCG host.

Fix this by calling cpu_physical_memory_dirty_bits_cleared() when
dirty bits have been cleared.

Fixes: aa8dc04477 ("migration: synchronize memory bitmap 64bits at a time")

c2d5c4a7cb migration/ram: Add outgoing 'mapped-ram' migration
Implement the outgoing migration side for the 'mapped-ram' capability.

A bitmap is introduced to track which pages have been written in the
migration file. Pages are written at a fixed location for every
ramblock. Zero pages are ignored as they'd be zero in the destination
migration as well.

The migration stream is altered to put the dirty pages for a ramblock
after its header instead of having a sequential stream of pages that
follow the ramblock headers.

Without mapped-ram (current):        With mapped-ram (new):

f165cdf102 exec/ioport: Add portio_list_set_enabled()
Some SuperI/O devices such as the VIA south bridges or the PC87312 controller
allow to enable or disable their SuperI/O functions. Add a convenience function
for implementing this in the VIA south bridges.

The naming of the functions is inspired by its memory_region_set_enabled()
pendant.

ad2b652341 exec/ioport: Add portio_list_set_address()
Some SuperI/O devices such as the VIA south bridges or the PC87312 controller
are able to relocate their SuperI/O functions. Add a convenience function for
implementing this in the VIA south bridges.

This convenience function relies on previous simplifications in exec/ioport
which avoids some duplicate synchronization of I/O port base addresses. The
naming of the function is inspired by its memory_region_set_address() pendant.

4edee342f8 exec/ioport: Resolve redundant .base attribute in struct MemoryRegionPortio
portio_list_add_1() creates a MemoryRegionPortioList instance which holds a
MemoryRegion `mr` and an array of MemoryRegionPortio elements named `ports`.
Each element in the array gets assigned the same value for its .base attribute.
The same value also ends up as the .addr attribute of `mr` due to the
memory_region_add_subregion() call. This means that all .base attributes are
the same as `mr.addr`.

The only usages of MemoryRegionPortio::base were in portio_read() and
portio_write(). Both functions get above MemoryRegionPortioList as their
opaque parameter. In both cases find_portio() can only return one of the
MemoryRegionPortio elements of the `ports` array. Due to above observation any
element will have the same .base value equal to `mr.addr` which is also
accessible.

Hence, `mrpio->mr.addr` is equivalent to `mrp->base` and
MemoryRegionPortio::base is redundant and can be removed.
