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.
