Blue Swirl a313358636 block: avoid a warning on 64 bit hosts with long as int64_t
When building on a 64 bit host which uses 'long' for int64_t,
GCC emits a warning:
  CC    block/blkverify.o
/src/qemu/block/blkverify.c: In function `blkverify_verify_readv':
/src/qemu/block/blkverify.c:304: warning: long long int format, long
unsigned int arg (arg 3)

Rework a77cffe7e9 to avoid the warning.

Kevin Wolf 205ef7961f block: Allow bdrv_flush to return errors
This changes bdrv_flush to return 0 on success and -errno in case of failure.
It's a requirement for implementing proper error handle in users of bdrv_flush.

Stefan Weil a77cffe7e9 block: Use GCC_FMT_ATTR and fix a format error
Adding the gcc format attribute detects a format bug
which is fixed here.

v2:
Don't use type cast. BDRV_SECTOR_SIZE is unsigned long long,
so %lld should be the correct format specifier.

Stefan Hajnoczi d9d334176c blkverify: Add block driver for verifying I/O
The blkverify block driver makes investigating image format data
corruption much easier.  A raw image initialized with the same contents
as the test image (e.g. qcow2 file) must be provided.  The raw image
mirrors read/write operations and is used to verify that data read from
the test image is correct.

See docs/blkverify.txt for more information.
