Currently, the default values for werror and rerror have to be set
explicitly with blk_set_on_error() by the callers of blk_new(). The only
caller actually doing this is blockdev_init(), which is called for
BlockBackends created using -drive.
In particular, anonymous BlockBackends created with
-device ...,drive=<node-name> didn't get the correct default set and
instead defaulted to the integer value 0 (= BLOCKDEV_ON_ERROR_REPORT).
This is the intended default for rerror anyway, but the default for
werror should be BLOCKDEV_ON_ERROR_ENOSPC.
Set the defaults in blk_new() instead so that they apply no matter what
way the BlockBackend was created.

=== This is the QEMU I/O test suite ===
* Intro
This package contains a simple test suite for the I/O layer of qemu.
It does not require a guest, but only the qemu, qemu-img and qemu-io
binaries. This does limit it to exercise the low-level I/O path only
but no actual block drivers like ide, scsi or virtio.
* Usage
Just run ./check to run all tests for the raw image format, or ./check
-qcow2 to test the qcow2 image format. The output of ./check -h explains
additional options to test further image formats or I/O methods.
* Feedback and patches
Please send improvements to the test suite, general feedback or just
reports of failing tests cases to qemu-devel@nongnu.org with a CC:
to qemu-block@nongnu.org.
