d7482ffe97 whpx: Added support for breakpoints and stepping
Below is the updated version of the patch adding debugging support to WHPX.
It incorporates feedback from Alex Bennée and Peter Maydell regarding not
changing the emulation logic depending on the gdb connection status.

Instead of checking for an active gdb connection to determine whether QEMU
should intercept the INT1 exceptions, it now checks whether any breakpoints
have been set, or whether gdb has explicitly requested one or more CPUs to
do single-stepping. Having none of these condition present now has the same
effect as not using gdb at all.

8e3b0cbb72 Replace qemu_real_host_page variables with inlined functions
Replace the global variables with inlined helper functions. getpagesize() is very
likely annotated with a "const" function attribute (at least with glibc), and thus
optimization should apply even better.

This avoids the need for a constructor initialization too.

a8749d7cc9 memory: Make memory_region_readd_subregion() properly handle mapped aliases
memory_region_readd_subregion() wants to readd a region by first
removing it and then readding it. For readding, it doesn't use one of
the memory_region_add_*() variants, which is why fail to re-increment the
mr->mapped_via_alias counters, resulting in the
assert(alias->mapped_via_alias >= 0) in memory_region_del_subregion()
triggering the next time we call memory_region_readd_subregion().

Fix it by using memory_region_add_subregion_common() for readding the
region.

b21e238037 Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).

Commit e0220bb5b2 made cpus.c target-agnostic but didn't notice
the cpu_list() function is only defined in target-specific code
in "cpu.h". Move list_cpus() declaration to "exec/cpu-common.h"
because this function is not softmmu-specific and can also be
used by user-mode, along with moving its implementation to cpu.c,
which is compiled per target.

6538692e28 main-loop.h: introduce qemu_in_main_thread()
When invoked from the main loop, this function is the same
as qemu_mutex_iothread_locked, and returns true if the BQL is held.
When invoked from iothreads or tests, it returns true only
if the current AioContext is the Main Loop.

This essentially just extends qemu_mutex_iothread_locked to work
also in unit tests or other users like storage-daemon, that run
in the Main Loop but end up using the implementation in
stubs/iothread-lock.c.

Using qemu_mutex_iothread_locked in unit tests defaults to false
because they use the implementation in stubs/iothread-lock,
making all assertions added in next patches fail despite the
AioContext is still the main loop.

See the comment in the function header for more information.

15e09912b7 include: Move hardware version declarations to new qemu/hw-version.h
The "hardware version" machinery (qemu_set_hw_version(),
qemu_hw_version(), and the QEMU_HW_VERSION define) is used by fewer
than 10 files.  Move it out from osdep.h into a new
qemu/hw-version.h.

b85ea5fa2f include: Move qemu_madvise() and related #defines to new qemu/madvise.h
The function qemu_madvise() and the QEMU_MADV_* constants associated
with it are used in only 10 files.  Move them out of osdep.h to a new
qemu/madvise.h header that is included where it is needed.

cd6174843b exec/exec-all: Move 'qemu/log.h' include in units requiring it
Many files use "qemu/log.h" declarations but neglect to include
it (they inherit it via "exec/exec-all.h"). "exec/exec-all.h" is
a core component and shouldn't be used that way. Move the
"qemu/log.h" inclusion locally to each unit requiring it.
