The escaping of special characters was needed when the ids of the
permission checkboxes for shares were based on the "shareWith" field.
Since they are based on the "shareId" field the escaping is no longer
needed, as the "sharedId" is expected to always contain compatible
characters.

The ids of permission checkboxes for shares were generated using the
"shareWith" field of the share. The "shareWith" field can contain spaces
(as spaces are allowed, for example, in user or circle names), so this
could cause the id attribute of the HTML element to contain spaces too,
which is forbidden by the HTML specification.
It is not just a "formal" issue, though; when the list was rendered, if
the id contained a space the selector to get the checkbox element was
wrong (as it ended being something like
"#canEdit-view1-name with spaces") and thus the initial state of the
checkbox was not properly set.
Besides that, "shareWith" can contain too single quotes, which would
even cause the jQuery selector to abort the search and leave the UI in
an invalid state.
Instead of adding more cases to the regular expression to escape special
characters and apply it too when the ids are created now the ids of
permission checkboxes for shares are based on the "shareId" field
instead of on "shareWith", as "shareId" is expected to always contain
compatible characters.

Before, whenever a pending operation (getting the suggestions,
confirming a share or selecting a recipient) finished the working icon
was hidden and the confirm button was shown again, even if there were
other pending operations (the most common case is typing slowly on the
input field, as several operations to get the suggestions could pile if
the server response is not received fast enough). Now, the working icon
is not hidden until the last pending operation finishes.

The suggestions depend on the results returned by the server, but also
on the sharees already shared with. Due to that adding a share changes

share is added.

When a share is confirmed the suggestions are got to check if there is
an exact match. Usually the suggestions were already got with the same
parameters in order to fill the autocomplete dropdown, so to avoid a

Besides confirming a share by clicking on the confirm button now it is
possible to do it by pressing enter on the input field.
Clicking on the confirm button implicitly hides the autocomplete
dropdown. On the other hand, pressing enter on the input field does not,
so the autocompletion must be disabled and closed when the confirmation
begins and then enabled again once it finishes. Otherwise the
autocomplete dropdown would be visible and it would be possible to
interact with it while the share is being confirmed.
The order in which the input field and the autompletion are disabled is
important. Internally, the autocompletion sets a timeout when the input
field is modified that requests the suggestions to the server and then
shows them in the dropdown. That timeout is not cancelled when the
autocompletion is disabled, but when the input field loses its focus and
the autocompletion is not disabled. Therefore, the input field has to be
disabled (which causes it to lose the focus) before the autocompletion
is disabled. Otherwise it could happen that while a share is being
confirmed the timeout ends, so an autocompletion request is sent and
then, once the share is successfully confirmed and thus the
autocompletion is enabled again, the request is received and the
autocomplete dropdown is shown with the old suggestions. Strange, but
possible nevertheless ;-)

"_getSuggestions" returned all the suggestions from the server, which
are composed by exact matches and partial matches. Now the exact matches
are also returned on their own parameter. This will be used by the
button to confirm a share.
Note that until now the order of the suggestions was "exact users,
partial users, exact groups, partial groups, exact..."; this commit also
changes that order to become "exact users, exact groups, exact...,
partial users, partial groups, partial...". This is not a problem, as
the suggestions were used in the autocomplete dropdown, and this new
order is arguably better than the old one, as all exact matches appear
now at the beginning.

Before, the avatar for a circle share was generated using the
"share_with" field as the seed for "imageplaceholder". Due to this, when
the "share_with" field is set to the circle ID the character shown in
the avatar was just a random character instead of the first character of
the display name. Now the "share_with" is still used as the seed for the
colour, but the display name is used as the text of the avatar.
This adds support for "share_with" fields set to the circle ID while
being backwards compatible with "share_with" fields set to the circle
name.
Note that when "share_with" fields is set to the circle name the colour
of the avatar is different in the list of suggested sharees and in the
list of current sharees, but that also happened before these changes
(due to a different seed being used in each place).

When finishing the setup of Nextcloud through the WebUI (setting admin
user and database) Firefox offers to save the username and password.
However, the password was shown in both the username and password fields
of the Firefox password manager dialog.
The problem was that the password input element (in the HTML form) is
cloned in a text input element, which is used to show the password in
plain text when clicking on the "Show password" button. As it was a text
input immediately followed by a password input Firefox seemed to assume
that it had to be the username and ignored the real username field, no
matter the value set for the "autocomplete" attribute. Now the cloned
text input is added after the password input, so Firefox no longer
thinks that the cloned text input is the username field and the password
manager dialog shows the proper username instead.

When a Snap was disabled it stopped listening to the events, but if a
drag gesture was being performed it was kept as active. Thus, when the
Snap was enabled again move events were handled as if the Snap had never
been disabled, causing the gesture handling to continue where it was
left.
When the Snap for the navigation bar is disabled by an app it could be
as a result of a different gesture being recognized by the app (for
example, a vertical swipe) once both gestures have started. In that case
when the other gesture ends and the Snap is enabled again any pointer
movement will cause the navigation bar to slide until an "up" event is
triggered again (obviously not the desired behaviour).
Due to all this now when the Snap for the navigation bar is disabled by
an app the current drag gesture for the navigation bar is ended.
Note that this was added as a parameter to "Snap.disable()" instead of
done unconditionally to keep back-compatibility with the previous
behaviour (probably not really needed as it is unlikely that any app is
using the Snap library relying on that behaviour... but just in case).

On narrow screens a slide gesture can be used to open or close the
navigation bar. However that gesture could conflict at times with the
gestures used by certain apps (for example, if the right sidebar is open
the user may expect to close it by dragging it to the right, but that
could open the navigation bar instead depending on how the events are
handled). This commit makes possible for apps to disallow and allow
again that slide gesture.
In any case, note that applications can only disallow the gesture,
but they can not enable it. That is, they can prevent the gesture from
being used on narrow screens, but they can not make the gesture work on
wide screens; they are always limited by the base rules set by the core.

adjusted to adapt the behaviour of the plugin to the one expected by
"uploads/" in WebDAV v2.

The sort comparator checks the "isFavorite" property of the FileInfo
objects to compare. That property is set when the file list is loaded
and the response from the server is parsed, and thus a freshly loaded
file list has the proper sorting for favorite files. However, the
property is not set in other cases, like when the FileInfo objects are
derived from FileInfoModels due to a file being marked as a favorite or
a text editor being closed, which causes the file to be sorted in the
wrong position.
There is no need to add the property in those situations, though; in all
cases the TagsPlugin adds a "tags" array property that contains an
OC.TAG_FAVORITE tag, so that tag can be checked instead of "isFavorite".
Moreover, although "isFavorite" was added by the main "_parseFileInfo"
function it did not really belong there but to the "FileInfoParser" from
the TagsPlugin; however, as that property now is not used anywhere it
was removed altogether.
A cleaner solution would have been to make the sort comparator
extensible by plugins like other behaviours of the file list and then
add the sorting logic related to favorite files to the TagsPlugin.
However, right now only the TagsPlugin would need to alter the main
sorting logic, and it seems like a corner case anyway. Even if it is
implemented as a plugin, favorite files is a core feature, so for the
time being it will be taken into account directly in the main sorting
logic; making the sort comparator extensible by plugins is defered until
there are other use cases for that.

This implements the basics for the new app-password based authentication flow for our clients.
The current implementation tries to keep it as simple as possible and works the following way:
1. Unauthenticated client opens `/index.php/login/flow`
2. User will be asked whether they want to grant access to the client
3. If accepted the user has the chance to do so using existing App Token or automatically generate an app password.
If the user chooses to use an existing app token then that one will simply be redirected to the `nc://` protocol handler.
While we can improve on that in the future, I think keeping this smaller at the moment has its advantages. Also, in the
near future we have to think about an automatic migration endpoint so there's that anyways :-)
If the user chooses to use the regular login the following happens:
1. A session state token is written to the session
2. User is redirected to the login page
3. If successfully authenticated they will be redirected to a page redirecting to the POST controller
4. The POST controller will check if the CSRF token as well as the state token is correct, if yes the user will be redirected to the `nc://` protocol handler.
This approach is quite simple but also allows to be extended in the future. One could for example allow external websites to consume this authentication endpoint as well.
