qcow2: Factor next_refcount_table_size out

When the refcount table grows, it doesn't only grow by one entry but reserves
some space for future refcount blocks. The algorithm to calculate the number of
entries stays the same with the fixes, so factor it out before replacing the...

qcow2: Rewrite alloc_refcount_block/grow_refcount_table

The current implementation of alloc_refcount_block and grow_refcount_table has

qcow2: Fix access after end of array

If a write requests crosses a L2 table boundary and all clusters until the
end of the L2 table are usable for the request, we must not look at the next
L2 entry because we already have arrived at the end of the array....

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...
