The table size in the qcow2 cache is currently equal to the cluster
size. This doesn't allow us to use the cache memory efficiently,
particularly with large cluster sizes, so we need to be able to have
smaller cache tables that are independent from the cluster size. This
patch adds a new field to Qcow2Cache that we can use instead of the
cluster size.
The current table size is still being initialized to the cluster size,
so there are no semantic changes yet, but this patch will allow us to
prepare the rest of the code and simplify a few function calls.

To maintain load/store disabled bitmap there is new approach:
- deprecate @autoload flag of block-dirty-bitmap-add, make it ignored
- store enabled bitmaps as "auto" to qcow2
- store disabled bitmaps without "auto" flag to qcow2
- on qcow2 open load "auto" bitmaps as enabled and others
as disabled (except in_use bitmaps)
Also, adjust iotests 165 and 176 appropriately.

sd_prealloc() will now preallocate the area [old_size, new_size). As
before, it rounds to buf_size and may thus overshoot and preallocate
areas that were not requested to be preallocated. For image creation,
this is no change in behavior. For truncation, this is in accordance
with the documentation for preallocated truncation.

glfs_close() is a classical clean-up operation, as can be seen by the
fact that it is executed even if the truncation before it failed.
Also, moving it to clean-up makes it more clear that if it fails, we do

Now that memory_region_sync_dirty_bitmap is NULL, we can unify its
loop with memory_global_dirty_log_sync's. The only difference is
that memory_region_sync_dirty_bitmap will no longer call log_sync on
FlatRanges that do have a zero dirty_log_mask, but this is okay because
video memory is always registered with the dirty page logging mechanism.

qemu-io puts the TTY into non-canonical mode, which means no EOF processing is
done and thus getchar() will never return the EOF constant. Instead we have to
query the TTY attributes to determine the configured EOF character (usually
Ctrl-D / 0x4), and then explicitly check for that value. This fixes the
regression that prevented Ctrl-D from triggering an exit of qemu-io that has
existed since readline was first added in
