When the browser reports a drag of items other than files (for example,
text) and then triggers a drop event with no files no error message
should be shown to the user, as in that case there would be no highlight
of the drop zone and no indication that the drop would be valid (except
for the mouse cursor); the error message should be shown only when
the drop event with no files follows a file drag.

The highlighting was removed in Firefox when the cursor was no longer
moving to handle the behaviour of reporting a file drag and then
providing no files in the drop event. That behaviour (which was only
present in Firefox 48 and 49) is already handled with the "dropnofiles"
callback, so that special handling is no longer needed.

When a file is dragged from the desktop to the file list the file list
is highlighted, and when the file is finally dropped or the drag
operation is cancelled the highlighting is removed. In some cases, due
to a wrong implementation, a browser may end a file drag with a drop
with no files (for example, when a folder or text is dragged), which
would cause the highlight to not be removed. Now those cases are handled
with the "dropnofiles" callback, which restores the UI and also shows a
message to the user.
The error message is just a generic one, as in some cases it is not even
possible to know whether the problem came from a text drag or a folder
drag, and whether the problem appears or not depends on the browser,
version and even operating system.

The jQuery Plugin triggers the "dragover" callback when the browser
triggers the "dragover" event and the types in their DataTransfer
include a "Files" item. It also triggers the "drop" callback when the
browser triggers the "drop" event and the list of files in its
DataTransfer is not empty.
Unfortunately some browsers may trigger "dragover" events with a
DataTransfer that includes a "Files" item and then trigger a "drop"
event with an empty list of files. When that happens the actions
performed in the "dragXXX" callbacks could be left hanging if they were
expected to be finished in the "drop" callback (for example, if the drop
zone was highlighted during the drag to be then restored when the file
was finally dropped). This commit adds the "dropnofiles" callback to be
able to handle those situations.

"disableDropState" was set as the event handler in 8d4e5747f3, but
the duplicated code was accidentally added back in 786e858d23.

Before any upload is submitted the upload is registered in a list of
known uploads; this is needed to retrieve the upload object at several
points of the upload process. When a chunked upload is submitted first a
directory to upload all the chunks is created and, once that is done,
the chunks are sent; in order to send a chunk the upload object needs to
be retrieved from the list of known uploads.
When all the active uploads were finished the list of known uploads was
cleared. However, an upload is not active until it actually starts
sending the data, so while waiting for the upload directory to be
created the upload is already in the list of known uploads yet not
active. Due to all this, if the active uploads finished while another
pending upload was waiting for the upload directory to be created that
pending upload would be removed from the list of known uploads too, and
once the directory was created and thus the chunks were sent a field of
a null upload object would be accessed thus causing a failure.
Instead of removing all the known uploads at once when the active
uploads finish now each upload is explicitly removed when it finishes.

The jQuery File Upload plugin triggers the "stop" event once there are
no more files being uploaded (even if some of them were added when
another upload was already in progress). Therefore, the progress bar
should be hidden in the "fileuploadstop" callback.
In some cases the "stop" event is not triggered and thus the progress
bar is not hidden once no more files are being uploaded. This is caused
by a race condition and it will be fixed in another commit; except in
buggy cases like that one (that need to be fixed anyway) it is safe to
hide the progress bar in the "fileuploadstop" callback.
In any case, note that the callbacks in "fileuploaddone" may be called
after the "stop" event was triggered and handled when using chunked
uploads. In that case once all the chunks are uploaded the assembled
file is moved to its final destination, so its promise could be resolved
after the "stop" event was triggered. Therefore a different approach
would be needed to keep the progress bar visible until the chunked
upload is truly finished, but for the time being the current one is good
enough.
Before this commit the progress bar was being hidden when the first
upload finished, either successfully or with an error, no matter if
there were other files being uploaded too.
The progress bar was being explicitly hidden also when the upload was
cancelled. When an upload is cancelled all the single uploads are
aborted, which triggers a "fail" event for each of them. However, the
"stop" event is always triggered when no more files are being uploaded,
so it is triggered too once all the single uploads were aborted. As all
the single uploads are immediately aborted in a loop when the general
upload is cancelled it makes no difference to hide the progress bar when
the first single upload is aborted or when all the single uploads were
aborted, so the progress bar is no longer explicitly hidden in the
former case.

The div that contains the elements related to the creation of new files,
and thus the upload button, is always present in the DOM; it is hidden
or shown based on the folder permissions by adding or removing the
"hidden" CSS class. However, as the other CSS classes for the div are
"actions" and "creatable" and a "display: flex" rule was defined for
".actions.creatable" below the "display: none" rule for
".actions.hidden" the last one took precedence and the div ended being
always visible, even if the "hidden" CSS class was set. Now the rules
for the ".actions.hidden" selector are defined below the rules for the
".actions.creatable" selector and thus the "display: none" rule is
applied as expected.

"getTotalWidth" is not more accurate; it is simply not clamped.
Moreover, "width/outerWidth" could be used in tests too, and also even
if "getTotalWidth" could be used in tests while others not that would
not be something to be stated in the API documentation, but in a
comment.

After the changes in the previous commit "_showCrumb" no longer shows
the menu, only the same crumb that was hidden by the last call to
"_hideCrumb". Therefore, if the crumb was hidden because it did not fit
there is no need to try to show it again, as it will still not fit.
Moreover, the calculated width for a hidden element is not always
accurate; in some cases the calculated width is lower than the actual
width (it happens, for example, when using a background image like the
"Share" icon), which causea the crumb to be shown even if there is not
enough room, which in the end causes the siblings to overflow the
contents.
No unit tests for this one, though; you will have to trust me on this,
sorry ;-)
