aio: clean up now-unused functions
Some cleanups can now be made, now that the main loop does not anymore needhooks into the bottom half code.

s390: autodetect map private
By default qemu will use MAP_PRIVATE for guest pages. This will writeprotect pages and thus break on s390 systems that dont support this feature.Therefore qemu has a hack to always use MAP_SHARED for s390. But MAP_SHAREDhas other problems (no dirty pages tracking, a lot more swap overhead etc.)...
bsd-user: fix build
Link in oslib objects also for BSD user, but avoid using the version ofqemu_vmalloc() defined in oslib-posix.c.

link the main loop and its dependencies into the tools
Using the main loop code from QEMU enables tools to operate fullyasynchronously. Advantages include better Windows portability (for somedefinition of portability) over glib's.
9pfs: improve portability to older systems
Small requirements on "new" features have percolated to virtio-9p-local.c.In particular, the utimensat wrapper actually only supports dirfd = AT_FDCWDand flags = AT_SYMLINK_NOFOLLOW in the fallback code. Remove the arguments...
Support running QEMU on Valgrind
Valgrind is a tool which can automatically detect many kinds of bugs.
Running QEMU on Valgrind with x86_64 hosts was not possible becauseValgrind aborts when memalign is called with an alignment larger than1 MiB. QEMU normally uses 2 MiB on Linux x86_64....

qemu_vmalloc: align properly for transparent hugepages and KVM
To make good use of transparent hugepages, KVM requires that guest-physicaland host-virtual addresses share the low 21 bits (as opposed to just the low12 bits normally required).
Adjust qemu_vmalloc() to honor that requirement. Ignore it for small regions...

Darwin: Fix compilation warning regarding the deprecated daemon() function
Changes since v1: create a wrapper function named qemu_daemon() in oslib-posix.cinstead of putting the OS specific workaround in qemu-nbd.c directly.
On OSX >= 10.5, daemon() is deprecated, resulting in the following warning:...
virtio-9p: fix build on !CONFIG_UTIMENSAT
This patch introduce a fallback mechanism for old systems that do notsupport utimensat(). This fix build failure with following warnings:

Consolidate oom_check() functions
This consolidates the duplicated oom_check() functions, as well assplitting them into OS dependant versions to avoid the #ifdefgrossness that was present in the old osdep.c version.

Move QEMU OS dependant library functions to OS specific files
This moves library functions used by both QEMU and the QEMU tools,such as qemu-img, qemu-nbd etc. from osdep.c to oslib-{posix,win32}.c
In addition it introduces oslib-obj.y to the Makefile set to be...
