sheepdog: implement direct write semantics

Sheepdog supports both writeback/writethrough write but has not yet supported
DIRECTIO semantics which bypass the cache completely even if Sheepdog daemon is
set up with cache enabled.

Suppose cache is enabled on Sheepdog daemon size, the new cache control is...

raw-posix: fix bdrv_aio_ioctl

When the raw-posix aio=thread code was moved from posix-aio-compat.c
to block/raw-posix.c, there was an unintended change to the ioctl code.
The code used to return the ioctl command, which posix_aio_read()
would later morph into a zero. This hack is not necessary anymore,...

block: make qiov_is_aligned() public

The qiov_is_aligned() function checks whether a QEMUIOVector meets a
BlockDriverState's alignment requirements. This is needed by
virtio-blk-data-plane so:

1. Move the function from block/raw-posix.c to block/block.c....

Replace remaining gmtime, localtime by gmtime_r, localtime_r

This allows removing of MinGW specific code and improves
reentrancy for POSIX hosts.

[Removed unused ret variable in qemu_get_timedate() to fix warning:
vl.c: In function ‘qemu_get_timedate’:
vl.c:451:16: error: variable ‘ret’ set but not used [-Werror=unused-but-set-variable]...

sheepdog: don't update inode when create_and_write fails

For the error case such as SD_RES_NO_SPACE, we shouldn't update the inode bitmap
to avoid the scenario that the object is allocated but wasn't created at the
server side. This will result in VM's IO error on the failed object....

block/raw-win32: Fix compiler warnings (wrong format specifiers)

Commit fbcad04d6bfdff937536eb23088a01a280a1a3af added fprintf statements
with wrong format specifiers.

GetLastError() returns a DWORD which is unsigned long, so %lu must be used.

raw-posix: add raw_get_aio_fd() for virtio-blk-data-plane

The raw_get_aio_fd() function allows virtio-blk-data-plane to get the
file descriptor of a raw image file with Linux AIO enabled. This
interface is really a layering violation that can be resolved once the...
