If CONFIG_USE_GUEST_BASE is not defined, gcc complains:
linux-user/mmap.c:235: error: comparison of unsigned expression >= 0 is always true
because RESERVED_VA is #defined to 0. Since mmap_find_vma_reserved()
will never be called anyway if RESERVED_VA is always 0, fix this by
simply #ifdef'ing away the function and its callsite.

A pointer to a size_t variable was passed as the void * pointer to
lduw_p() in virtio_net_receive(). Instead of acting on the 16-bit value
this caused failure on big-endian hosts.
Avoid this issue in the future by using stw_p() instead. In general we
should use ld*_p() for loading from target memory and st*_p() for
storing to target memory anyway, not the other way around.
Also tighten up a correct use of lduw_p() when stw_p() should be used
instead in virtio_net_get_config().

All targets except SH4 have the same cpu_halted() routine, and it has
only one caller. It is therefore a good candidate for inlining.
The difference is the handling of the intr_at_halt, which is necessary
to ignore SR.BL when sleeping. Move intr_at_halt handling out of it, by
setting this variable while executing the sleep instruction, and
clearing it when the CPU has been woken-up by an interrupt, whatever the
state of SR.BL. Also rename this variable in_sleep.

VMSTATE_PCIE_AER_ERRS is indeed useful for other emulation drivers.
Move it to hw/hw.h under the name of VMSTATE_STRUCT_VARRAY_POINTER_UINT16.
Also add VMSTATE_STRUCT_VARRAY_POINTER_INT32 which is more or less
the same as _UINT16 macro, except the fact it uses int32_t internally.

Hopefully all functions with printf like arguments now use format checking.
This was tested with default build configuration on linux
and windows hosts (including some cross compilations),
so chances are good that there remain few (if any) functions
without format checking.
Therefore the last comment in HACKING is no longer valid but misleading.
