[Qemu-devel] [PATCH v4 0/3] Support Archipelago as a QEMU block backend

[Chrysostomos Nanakos]

v4:
 - Move Archipelago QMP support from qapi-schema.json file to
   qapi/block-core.json. Fixe various typographic errors, thanks to
   Kevin Wolf and Eric Blake.
 - Use new .create_opts format, define new QemuOptsList structure and refactor
   qemu_archipelago_create function.

v3:
 - Break down initial patch from one to three. First patch implements
   Archipelago QEMU block backend with read/write functionality.
   Second patch implements .bdrv_create() and adds support for creating
   Archipelago images. Third patch adds QMP support.
 - Remove global variable g_xseg_init, make xseg_initialize(), xseg_join()
   and xseg_leave() reentrant and thread-safe.
 - Introduce new enum BlockdevOptionsArchipelago for the QMP support.

v2:
 - Implement .bdrv_parse_filename() function to convert the shortuct version
   with a single string to the individual options.
 - Remove global variables and move relevant fields to ArchipelagoAIOCB struct.
 - Remove ArchipelagoConf struct and use the relevant fields as individual
   arguments.
 - Remove ArchipelagoCB struct and use ArchipelagoAIOCB instead.
 - Remove ArchipelagoThread struct and move relevant fields to
   ArchipelagoAIOCB instead. Now an I/O thread is spawned for per-device to
   handle all async I/O requests.
 - Remove double data copy, use qemu_iovec_from_buf() and copy data directly
   to the destination buffer.
 - Remove archipelago_aio_bh_cb() function, a full request is completed in
   qemu_archipelago_complete_aio() instead.
 - Resolve proposed changes from Kevin Wolf and miscellaneous style issues.
