qcow2: Fix metadata preallocation

The wrong version of the preallocation patch has been applied, so this is the
remaining diff.

We can't use truncate to grow the image file to the right size because we don't
know if metadata has been written after the last data cluster. In this case...

Fix spelling in comment.

The company which made Virtual PC was Connectix.
They use the magic string "conectix" in their disk images.

raw-posix: refactor AIO support

Currently the raw-posix.c code contains a lot of knowledge about the
asynchronous I/O scheme that is mostly implemented in posix-aio-compat.c.
All this code does not really belong here and is getting a bit in the
way of implementing native AIO on Linux....

raw-posix: add Linux native AIO support

Now that do have a nicer interface to work against we can add Linux native
AIO support. It's an extremly thing layer just setting up an iocb for
the io_submit system call in the submission path, and registering an...

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
have AIO available on posix hosts, and it will also allow enabling the I/O
thread unconditionally once it's ready.
