Commit 3d068aff (3.0) introduced NBD_MAX_BITMAP_EXTENTS as a limit on
how large we would allow a reply to NBD_CMD_BLOCK_STATUS to grow when
it is visiting a qemu:dirty-bitmap: context. Later, commit fb7afc79
(3.1) reused the constant to limit base:allocation context replies,
although the name is now less appropriate in that situation.
Rename things, and improve the macro to use units.h for better
legibility. Then reformat the comment to comply with checkpatch rules
added in the meantime. No semantic change.

common.nbd's nbd_server_set_tcp_port() tries to find a free port, and
then uses it for the whole test run. However, this is racy because even
if the port was free at the beginning, there is no guarantee it will
continue to be available. Therefore, 233 currently cannot reliably be
run concurrently with other NBD TCP tests.
This patch addresses the problem by dropping nbd_server_set_tcp_port(),
and instead finding a new port every time nbd_server_start_tcp_socket()
is invoked. For this, we run qemu-nbd with --fork and on error evaluate
the output to see whether it contains "Address already in use". If so,
we try the next port.
On success, we still want to continually redirect the output from
qemu-nbd to stderr. To achieve both, we redirect qemu-nbd's stderr to a
FIFO that we then open in bash. If the parent process exits with status
0 (which means that the server has started successfully), we launch a
background cat process that copies the FIFO to stderr. On failure, we
read the whole content into a variable and then evaluate it.
While at it, use --fork in nbd_server_start_unix_socket(), too. Doing
so allows us to drop nbd_server_wait_for_*_socket().
Note that the reason common.nbd did not use --fork before is that
qemu-nbd did not have --pid-file.

qemu_nbd_pipe() currently unconditionally reads qemu-nbd's output. That
is not ideal because qemu-nbd may keep stderr open after the parent
process has exited.
Currently, the only user of qemu_nbd_pipe() is 147, which discards the
whole output if the parent process returned success and only evaluates
it on error. Therefore, we can replace qemu_nbd_pipe() by
qemu_nbd_early_pipe() that does the same: Discard the output on success,
and return it on error.

On Mojave, absolute input device, i.e. tablet, had trouble re-grabbing
the cursor in re-entry into the virtual screen area. In some cases,
the `window` property of NSEvent object was nil after cursor exiting from
window, hinting that the `-locationInWindow` method would return value in
screen coordinates. The current implementation used raw locations from
NSEvent without considering whether the value was for the window coordinates
or the macOS screen coordinates, nor the zooming factor for Zoom-to-Fit in
fullscreen mode.
In fullscreen mode, the fullscreen cocoa window might not be the key
window, therefore the location of event in virtual coordinates should
suffice.
This patches fixed boundary check methods for cursor in normal
and fullscreen with/without Zoom-to-Fit in Mojave.
Note: CGRect, -convertRectToScreen: and -convertRectFromScreen: were
used in coordinates conversion for compatibility reason.
