block: remove bdrv_is_allocated_above/bdrv_co_is_allocated_above distinction

Now that bdrv_is_allocated detects coroutine context, the two can
use the same code.

block: introduce bdrv_get_block_status API

For now, bdrv_get_block_status is just another name for bdrv_is_allocated.
The next patches will add more flags.

This also touches all block drivers with a mostly mechanical rename. The
sole exception is cow; because it calls cow_co_is_allocated from the read...

block: define get_block_status return value

Define the return value of get_block_status. Bits 0, 1, 2 and 9-62
are valid; bit 63 (the sign bit) is reserved for errors. Bits 3-8
are left for future extensions.

The return code is compatible with the old is_allocated API: if a driver...

block: implement reference count for BlockDriverState

Introduce bdrv_ref/bdrv_unref to manage the lifecycle of
BlockDriverState. They are unused for now but will used to replace
bdrv_delete() later.

block: make bdrv_delete() static

Manage BlockDriverState lifecycle with refcnt, so bdrv_delete() is no
longer public and should be called by bdrv_unref() if refcnt is
decreased to 0.

This is an identical change because effectively, there's no multiple
reference of BDS now: no caller of bdrv_ref() yet, only bdrv_new() sets...

block: make bdrv_co_is_allocated static

bdrv_is_allocated can detect coroutine context and go through a fast
path, similar to other block layer functions.

memory: Provide separate handling of unassigned io ports accesses

Accesses to unassigned io ports shall return -1 on read and be ignored
on write. Ensure these properties via dedicated ops, decoupling us from
the memory core's handling of unassigned accesses....
