qcow2: Metadata preallocation

This introduces a qemu-img create option for qcow2 which allows the metadata to
be preallocated, i.e. clusters are reserved in the refcount table and L1/L2
tables, but no data is written to them. Metadata is quite small, so this...

block/vdi.c: Fix several bugs

  • The code for option '-static' was wrong, so image creation
    always created static images.
  • Static images created with qemu-img did not set header entry
    blocks_allocated.
  • The size of the block map must be rounded to the next multiple...

eliminate errors about unused results in block/vpc.c

These errors come up when compiling with gcc-4.3.3 and some older headers:

/scratch/froydnj/qemu.git/block/vpc.c: In function 'vpc_create':
/scratch/froydnj/qemu.git/block/vpc.c:514: error: value computed is not used...

make pthreads mandatory

As requested by Anthony make pthreads mandatory. This means we will always

Add new block driver for the VDI format (only aio supported)

This is a new block driver written from scratch
to support the VDI format in QEMU.

VDI is the native format used by Innotek / SUN VirtualBox.

Latest changes:

  • stripped down version
    (code for synchronous operations and experimental code removed)...

vmdk: Fix backing file handling

Instead of storing the backing file in its own BlockDriverState, VMDK uses the
BlockDriverState of the raw image file it opened. This is wrong and breaks
functions that access the backing file or protocols. This fix replaces all...
