[PATCH v2 0/9] Cleanup of qemu_oom_check() and qemu_memalign() |

This series does some cleanup of the qemu_oom_check() and
qemu_memalign() functions; I started looking at the first of these and
found myself wanting to tidy some stuff relating to the second in the
process. The TLDR is that this series removes qemu_oom_check() (which
was mostly being misused), unifies the POSIX and Win32 versions of
qemu_memalign() and qemu_try_memalign(), and moves the prototypes out
of osdep.h.
Changes v1->v2:
* Replacement patch 4, which takes the approach discussed in
comments on v1 of making all our implementations handle
size == 0 by doing a size 1 allocation
* two #include lines accidentally added in patch 7 are
moved to patch 6 where they belong (fixes compile failure
during bisect)
Patch 4 is the only one needing review.
(When I came to make this change I decided that there was
just a bit more involved than I was happy making in passing
while assembling a pull request.)
thanks
