don't dereference NULL after failed strdup

Most of these are obvious NULL-deref bug fixes, for example,
the ones in these files:

block/curl.c
  net.c
  slirp/misc.c

and the first one in block/vvfat.c.
The others in block/vvfat.c may not lead to an immediate segfault, but I...

qcow2: Fix signedness bugs

Checking for return codes < 0 isn't really going to work with unsigned
types. Use signed types instead.

Do not use dprintf

dprintf is already claimed by POSIX1, and on at least one system
is implemented as a macro

block/raw-posix: Abort on pread beyond end of non-growable file

This shouldn't happen under any normal circumstances. However, it looks like
it's possible to achieve this with corrupted images. Without this patch
raw_pread is hanging in an endless loop in such cases....

win32: pair qemu_memalign() with qemu_vfree()

Win32 suffers from a very big memory leak when dealing with SCSI devices.
Each read/write request allocates memory with qemu_memalign (ie
VirtualAlloc) but frees it with qemu_free (ie free).
Pair all qemu_memalign() calls with qemu_vfree() to prevent such leaks....

qcow2: rename two QCowAIOCB members

The n member is not very descriptive and very hard to grep, rename it to
cur_nr_sectors to better indicate what it is used for. Also rename
nb_sectors to remaining_sectors as that is what it is used for.

block: kill BDRV_O_CREAT

The BDRV_O_CREAT option is unused inside qemu and partially duplicates
the bdrv_create method. Remove it, and the -C option to qemu-io which
isn't used in qemu-iotests anyway.

Found some places that seems needs this explicitly, now that
read-write is not the default.
