You provide some motivation for this, but only in your cover letter:
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.
Please put it into the commit message, so it gets committed.
An example to illustrate how QArray is better than GArray (for some
value of "better") would help make your case that QArray is worth its
maintenance cost.
