its not used anymore

No need to use SystemRandom() here, as this is not needed for security
purposes

The reason for signal.signal(signal.SIGPIPE, signal.SIG_DFL)

Python ignores SIGPIPE by default ( signal(SIGPIPE, SIG_IGN) )
Write on a socket return then an error 32 EPIPE, which naturally
turns into an exception.

signal.SIG_DFL restores normal UNIX behavior

We dont need this module anymore

We already determine LANG in initialize_lang()

getdefaultlocale() takes env var LANG into consideration

We default to 'en' for LANG if LC_ALL=C is set

The attributes were removed in 8e09fd92

Sets are unordered and list with push/pop acts as LIFO, though we need FIFO.
Since the number of elements is tiny, no need to use deque.

Addresses #9120

if autopopup_chat_opened is activated no control is found because
the event that triggered the notification is already deleted when
the notification is clicked by the user. So instead of searching
for the event, search for the control with jid/account.

Fixes #9124

if oob uri == body there is no need to show the uri
below the message

To use this alias `account_id` with `account`

Example: SELECT account_id as account FROM logs

These platforms integrate a file preview in their native filechoosers

Before: After a rightclick -> "Modify Account" on an account in the
roster the preferences of the account are shown but the account is not
selected in the account list.
After: account will be selected in the account list too

Use GtkFileChooserDialog only when we need previews, default to
NativeFileChooser otherwise.

GtkFileChooserDialogs have a long list of issues, so lets only use it
if we gain something from it.

Flatpak should only run NativeFileChoosers because its sandboxed and
this is needed for security purposes. As a result of that, Flatpak Users
dont have image previews in the FileOpenDialogs

Refactor all FileChoosers for a more simple approach when we use them

Add a new SendFileDialog, so we dont have to put widgets into the FileChooser
which forces non-native Dialogs.

regression was introduced in e2383fd7

Using a FileChooserDialog for this is overkill, use FileChooserButton
in the future

This was nonfunctional for a long time and nobody complained

- Move code into ui file
- Use FileChooserButton instead of FileChooserDialog
- Make methods private
- Simplify code

We use now a Gtk.FileChooserButton for client certs

Fixes #9083

Dont save fingerprints to config and check certs with our own methods.
We should trust openssl to do all necessary checks.

Self signed certs can be added to cacert.pem and will not show up as
an error until the cert changes.

nbxmpp now saves all ssl errors and passes them, so now we loop over
all errors until all are confirmed or ignored by the user

Also cacerts are now saved in utf-8

Fixes #9106

As all Windows versions have a status icon and most Windows users expect this

Fixes #9031
