aio: rename AIOPool to AIOCBInfo

Now that AIOPool no longer keeps a freelist, it isn't really a "pool"
anymore. Rename it to AIOCBInfo and make it const since it no longer
needs to be modified.

block: replace unchecked strdup/malloc/calloc with glib

Most of the codebase as been converted to use glib memory allocation
functions. There are still a few instances of malloc/calloc in the
block layer and qemu-io. Replace them, especially since they do not...

block: drop redundant bdrv_flush implementation

Block drivers now only need to provide either of .bdrv_co_flush,
.bdrv_aio_flush() or for legacy drivers .bdrv_flush(). Remove
the redundant .bdrv_flush() implementations.

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...

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.

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.

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...
