The AioContext pointer argument to co_aio_sleep_ns() is only used for
the sleep timer. It does not affect where the caller coroutine is
resumed.
Due to changes to coroutine and AIO APIs it is now possible to drop the
AioContext pointer argument. This is safe to do since no caller has
specific requirements for which AioContext the timer must run in.
This patch drops the AioContext pointer argument and renames the
function to simplify the API.

If curl_global_init() fails, per the documentation no other curl
functions may be called, so make sure to check the return value.
Also, some minor changes to the initialization latch variable 'inited':
- Make it static in the file, for clarity
- Change the name for clarity
- Make it a bool

If users set an unreasonably low speed (like one byte per second), the
calculated delay may exceed many hours. While we like to punish users
for asking for stupid things, we do also like to allow users to correct
their wicked ways.
When a user provides a new speed, kick the job to allow it to recalculate
its delay.

initialized from sync_bitmap and it is more informative: we will not try
to process data, that is already in progress (by write notifier).

Set fake progress for non-dirty clusters in copy_bitmap initialization,
to. It simplifies code and allows further refactoring.
This patch changes user's view of backup progress, but formally it
doesn't changed: progress hops are just moved to the beginning.
Actually it's just a point of view: when do we actually skip clusters?
We can say in the very beginning, that we skip these clusters and do
not think about them later.
Of course, if go through disk sequentially, it's logical to say, that
we skip clusters between copied portions to the left and to the right
of them. But even now copying progress is not sequential because of
write notifiers. Future patches will introduce new backup architecture
which will do copying in several coroutines in parallel, so it will
make no sense to publish fake progress by parts in parallel with
other copying requests.
