The current use of aliased memory regions causes us 2 problems: firstly the
output of "info qom-tree" is absolutely huge and difficult to read, and
secondly we have already reached the internal limit for memory regions as
adding any new memory region into the mac-io region causes QEMU to assert
with "phys_section_add: Assertion `map->sections_nb < TARGET_PAGE_SIZE'
failed".
Implement the mac-io region aliasing using a single IO memory region that
applies IO_SLICE_MASK representing the maximum size of the aliased region and
then forwarding the access to the existing mac-io memory region using the
address space API.

This reverts commit d7ee93e243.
That commit tries to make a field in the CPUState struct not be
present when CONFIG_USER_ONLY is set. Unfortunately, you can't
conditionally omit fields in structs like this based on ifdefs that
are set per-target. If you try it, then code in files compiled
per-target (where CONFIG_USER_ONLY is or can be set) will disagree
about the struct layout with files that are compiled once-only (where
this kind of ifdef is never set).
This manifests specifically in 'make check-tcg' failing, because code
in cpus-common.c that sets up the CPUState::cpu_index field puts it
at a different offset from the code in plugins/core.c in
qemu_plugin_vcpu_init_hook() which reads the cpu_index field. The
latter then hits an assert because from its point of view every
thread has a 0 cpu_index. There might be other weird behaviour too.
Mostly we catch this kind of bug because the CONFIG_whatever is
listed in include/exec/poison.h and so the reference to it in
build-once source files will then cause a compiler error.
Unfortunately CONFIG_USER_ONLY is an exception to that: we have some
places where we use it in "safe" ways in headers that will be seen by
once-only source files (e.g. ifdeffing out function prototypes) and
it would be a lot of refactoring to be able to get to a position
where we could poison it. This leaves us in a "you have to be
careful to walk around the bear trap" situation...
