block: Add reference parameter to bdrv_open()

Allow bdrv_open() to handle references to existing block devices just as
bdrv_file_open() is already capable of.

qcow2: Set zero flag for discarded clusters

Instead of making the backing file contents visible again after a discard
request, set the zero flag if possible (i.e. on version >= 3).

block: Change BDS parameter of bdrv_open() to **

Make bdrv_open() take a pointer to a BDS pointer, similarly to
bdrv_file_open(). If a pointer to a NULL pointer is given, bdrv_open()
will create a new BDS with an empty name; if the BDS pointer is not
NULL, that existing BDS will be reused (in the same way as bdrv_open()...

Use error_is_set() only when necessary

error_is_set(&var) is the same as var != NULL, but it takes
whole-program analysis to figure that out. Unnecessarily hard for
optimizers, static checkers, and human readers. Dumb it down to
obvious.

Gets rid of several dozen Coverity false positives....

block: mirror - use local_err to avoid NULL errp

When starting a block job, commit_active_start() relies on whether *errp
is set by mirror_start_job. This allows it to determine if the mirror
job start failed, so that it can clean up any changes to open flags from...

block: Don't throw away errno via error_setg

There are a handful of places in the block layer where a failure path
has a valid -errno value, yet error_setg() is used. Those instances
should instead use error_setg_errno(), to preserve as much error
information as possible....

block: Add notes to iSCSI's .bdrv_open and .bdrv_reopen_prepare

iSCSI currently does not need to do any actions to support the
current usage of bdrv_reopen(). However, it is important to note
a couple of things: 1.) A connection will not be re-established to...

raw: Fix BlockLimits passthrough

raw copies over the BlockLimits of bs->file during bdrv_open().
However, since commit d34682cd it is immediately overwritten during
bdrv_refresh_limits(). This caused all fields except for
opt_transfer_length and opt_mem_alignment (which happen to be correctly...
