This code fix is by Stefan Monnier (Bug#57699).
* src/process.c (init_process_emacs) [HAVE_GLIB && !WINDOWSNT]:
Adjust to Glib 2.73.2 behavior change on Linux kernel 5.3+.
These were announced as removed in Emacs 28.1 NEWS, but apparently
never actually deleted: only their obsoletion warning was removed.
So the warnings were reintroduced in Emacs 28.2, and we now actually
delete them here instead.
* src/process.c (Fset_process_filter_multibyte)
(Fprocess_filter_multibyte_p): Delete functions obsolete since
Emacs 23.

* lisp/subr.el (process-filter-multibyte-p)
(set-process-filter-multibyte): Delete obsoletion.
* lisp/erc/erc-dcc.el (erc-dcc-server): Don't use obsolete functions.
Don't say that a value is a fixnum if small enough and a bignum
otherwise, because that is now how Lisp integers always work,
and we generally don't expose the fixnum/bignum difference to the user
unless really necessary.

If a TLS handshake is attempted before the completion of an
asynchronous TCP connection has been ascertained, our local state will
not be set up correctly for further progress and the sentinel "open"
event will never be sent. This can occur if sufficient time passes
after the initiation of an async TCP connection so that by the time
`wait_reading_process_output` is called, the connection has already
been established on the TCP level.
This somewhat timing-sensitive bug has plagued HTTPS connections on
some platforms, notably macOS, for a long time (bug#49449).
