Peter Maydell 4715856a68 linux-user: Add some new blk ioctls
Add some new blk ioctls (these are 0x12,119 through
to 0x12,127). Several of these are used by mke2fs; this silences
the warnings:

Peter Maydell f2c2fb50be linux-user: Correct type for LOOP_GET_STATUS{,64} ioctls
The LOOP_GET_STATUS and LOOP_GET_STATUS64 ioctls were incorrectly
defined as IOC_W rather than IOC_R, which meant we weren't
correctly copying the information back from the kernel to the guest.
The loop_info64 structure definition was also missing a member
and using the wrong type for several 32-bit fields.

In particular, this meant that "kpartx -d image.img" didn't work
and "losetup -a" behaved strangely. Correct the ioctl type definitions.

Peter Maydell a4a2c51f90 linux-user: Correct type for BLKSSZGET
The BLKSSZGET ioctl takes an argument which is a pointer to an int.
We were incorrectly declaring it to take a pointer to a long, which
meant that we would incorrectly write to memory which we should not
if the guest is a 64-bit architecture.

In particular, kpartx uses this ioctl to write to an int on the
stack, which tends to result in it crashing immediately.

Alexander Graf a59b5e35d1 linux-user: Convert blkpg to use a special subop handler
