[PATCH 0/5] introduce QArray

[Christian Schoenebeck]

Patches 1 and 2 introduce include/qemu/qarray.h which implements a deep auto
free mechanism for arrays. Unlike GArray it does not require special macros,
function calls or member dereferencing to access the individual array
elements. So existing C-style array code can be retained with only very
little changes.

In this initial version QArray only supports the concept of unique pointers,
i.e. it does not support reference counting. The array (and all dynamically
allocated memory of individual array elements) is auto freed once execution
leaves the scope of the reference variable (unique pointer) associated with
the array.

Patches 3..5 are provided (e.g. as example) for 9p being the first user of
this new QArray API. These particular patches 3..5 are rebased on my
current 9p queue: https://github.com/cschoenebeck/qemu/commits/9p.next
which are basically just the following two queued patches:
