This is a boiler-plate _nofail variant of qemu_opts_create. Remove and use error_abort in call sites. null/0 arguments needs to be added for the id and fail_if_exists fields in affected callsites due to argument inconsistency between the normal and no_fail variants.

Commit f35c934a accidently disabled iscsi_co_get_block_status for all libiscsi versions. Its not possible to check for enumeration constants in the C preprocessor.

Replace .bdrv_aio_discard with .bdrv_co_discard so that discard requests can be split in multiple parts, each for a small amount of sectors.

Manage BlockDriverState lifecycle with refcnt, so bdrv_delete() is no longer public and should be called by bdrv_unref() if refcnt is decreased to 0. This is an identical change because effectively, there's no multiple reference of BDS now: no caller of bdrv_ref() yet, only bdrv_new() sets bs->refcnt to 1, so all bdrv_unref() now actually delete the BDS.

this patch adds iscsi_truncate which effectively allows for online resizing of iscsi volumes. for this to work you have to resize the volume on your storage and then call block_resize command in qemu which will issue a readcapacity16 to update the capacity. v4: - factor out complete readcapacity logic into a separate function - handle capacity change check condition in readcapacity function (this happens if the block_resize cmd is the first iscsi task executed after a resize on the storage) v3: - remove switch statement in iscsi_open - create separate patch for brdv_drain_all() in bdrv_truncate() v2: - add a general bdrv_drain_all() before bdrv_truncate() to avoid in-flight AIOs while the device is truncated - since no AIOs are in flight we can use a sync libiscsi call to re-read the capacity - factor out the readcapacity16 logic as it is redundant to iscsi_open() and iscsi_truncate().
