multi: remove PENDING + MSGSENT handles from the main linked list
As they are not driving transfers or any socket activity, the main loop
does not need to iterate over these handles. A performance improvement.
They are instead only held in their own separate lists.
'data->multi' is kept a pointer to the multi handle as long as the easy
handle is actually part of it even when the handle is moved to the
pending/msgsent lists. It needs to know which multi handle it belongs
to, if for example curl_easy_cleanup() is called before the handle is
removed from the multi handle.
Alll 'data->multi' pointers of handles still part of the multi handle
gets cleared by curl_multi_cleanup() which "orphans" all previously
attached easy handles.
This is take 2. The first version was reverted for the 8.0.1 release.
Assisted-by: Stefan Eissing
Closes #10801
