[PATCH v3 0/5] introduce QArray

[Christian Schoenebeck <qemu_oss@crudebyte.com>]

Patches 1 and 2 introduce include/qemu/qarray.h which implements a deep auto
free mechanism for arrays. See commit log of patch 1 for a detailed
explanation and motivation for introducing QArray.

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:

https://github.com/cschoenebeck/qemu/commit/7772715d43908235940f5b7dec68d0458b1ccdf4
https://github.com/cschoenebeck/qemu/commit/838b55e392ea7d52e714fdba1db777f658aee2cc

v2 -> v3:

    * Refactor QArrayRef() -> QARRAY_REF() [patch 1], [patch 5].

    * Commit log: Add more thorough explanation for the motivation of QArray,
      along with example for advantage over GArray [patch 1].

    * Commit log: Add reason for using MIT license for qarray.h instead of
      the standard QEMU license GPLv2+ [patch 1].

    * API doc comments: use 'size_t' type consistently in API doc example
      code [patch 1].

v1 -> v2:

    * Minor API comment changes [patch 1].

    * Perform strong type check by using __builtin_types_compatible_p()
      instead of a weak check using sizeof() [patch 2].
