  fix -net user checks by reordering checks

reorder slirp config options. first check the dns-server-address,
then check the first-dhcp-address. the original code was comparing
the first-dhcp-address with the default dns-server-address, not
the configured dns-server-address.

  make user networking hostfwd work with restrict=y

This patch allows the hostfwd option to override the restrict=y setting in
the user network stack, as explicitly stated in the documentation on the
restrict option:

     restrict=on|off
   If this option is enabled, the guest will be isolated, i.e. it
   will not be able to contact the host and no guest IP packets
   will be routed over the host to the outside. This option does
   not affect any explicitly set forwarding rules.

  exec.c: address_space_translate: handle access to addr 0 of 2^64 sized region

The memory API allows a MemoryRegion's size to be 2^64, as a special
case (otherwise the size always fits in a 64 bit integer). This meant
that attempts to access address zero in a 2^64 sized region would
assert in address_space_translate():

  #3  0x00007ffff3e4d192 in __GI___assert_fail#(assertion=0x555555a43f32
    "!a.hi", file=0x555555a43ef0 "include/qemu/int128.h", line=18,
    function=0x555555a4439f "int128_get64") at assert.c:103
  #4  0x0000555555877642 in int128_get64 (a=...)

  #5  0x00005555558782f2 in address_space_translate (as=0x55555668d140,
   /addr=0, xlat=0x7fffafac9918, plen=0x7fffafac9920, is_write=false)
    at exec.c:221

Fix this by doing the 'min' operation in 128 bit arithmetic
rather than 64 bit arithmetic (we know the result of the 'min'
definitely fits in 64 bits because one of the inputs did).

  exec: Resolve subpages in one step except for IOTLB fills

Except for the case of setting the IOTLB entry in TCG mode, we can avoid
the subpage dispatching handlers and do the resolution directly on
address_space_lookup_region. An IOTLB entry describes a full page, not
only the region that the first access to a sub-divided page may return.

This patch therefore introduces a special translation function,
address_space_translate_for_iotlb, that avoids the subpage resolutions.
In contrast, callers of the existing address_space_translate service
will now always receive the terminal memory region section. This will be
important for breaking the BQL and for enabling unaligned memory region.

This will allow to add support for unaligned memory regions: the subpage
container region can activate unaligned support unconditionally because
the read/write handler will now ensure that accesses are split as
required by calling address_space_rw. We can furthermore drop the
special handling of RAM subpages, address_space_rw takes care of this
already.

  memory: make section size a 128-bit integer

So far, the size of all regions passed to listeners could fit in 64 bits,
because artificial regions (containers and aliases) are eliminated by
the memory core, leaving only device regions which have reasonable sizes

An IOMMU however cannot be eliminated by the memory core, and may have
an artificial size, hence we may need 65 bits to represent its size.

  memory: iommu support

Add a new memory region type that translates addresses it is given,
then forwards them to a target address space.  This is similar to
an alias, except that the mapping is more flexible than a linear
translation and trucation, and also less efficient since the
translation happens at runtime.

The implementation uses an AddressSpace mapping the target region to
avoid hierarchical dispatch all the way to the resolved region; only
iommu regions are looked up dynamically.

The patch fixes this.

  Log Message:
  -----------
  memory: as_update_topology_pass: Improve comments

These comments were a little difficult to read. First one had
incorrect parenthesis. The part about attributes changing is
really applicable to the region being 'in both' rather than 'in
new'

Second comment has an obscure parenthetic about 'Logging may have
changed'. Made clearer, as this if is supposed to handle the case where
the memory region is unchanged (with the notable exception re logging).

  memory: render_memory_region: factor out fr constant setters

These 4 replicated lines set properties of fr that are constant over
the course of the function. Factor out their repeated setting (and also
guards against them being set multiple times in the loop below).
