Telegram-purple, as well as every libtgl-based application, does not
work anymore (i tested).

Port's page[1] says it is abandoned since 2021 and may or may not work
(it did for some time, but now does not).  It points to a new project
for a libpurple plugin based on the last newest Telegram API:
tdlib-purple[2], which is supposed to work until Telegram decides to
change it all again.

I wrote a port for net/tdlib-purple and updated the net/tdlib port in
order for it to compile.  I am going to send those on other emails.
