For some reason Ubuntu's version of screen includes timestamps in the
output of `screen -list`. The timestamps aren't present on other
distributions (tested on Fedora and Arch Linux), nor when building from
source. This commit fixes the regex so that with or without the
timestamp, fish will correctly show suggestions for screen sessions.
prettify_node_recursive is replaced with prettify_node_nrecursive
explicite stack is used instead.

Now Sphinx is my best friend
This switches the docs to build with Sphinx instead of Doxygen.
There's a lot remaining to do: see #5696. However it is painful to mirror
docs changes from Doxygen to Sphinx, so it is better to switch over now
even in this incomplete state.
The last Doxygen build is tagged as 'last_doxygen'
Closes#5640
sphinx expects that the description for a command (as appearing in its man
page) be provided in conf.py, not in the rst file itself. LLVM handles this
with some custom Python code that parses it out of the file. Do the same
thing in fish.
fish's signal handlers are now sufficiently innocuous that there should
be no reason to block signals (outside of temporarily, when creating a
thread and we need to manipulate the signal mask).
Prior to this fix, an "event" was used as both a predicate on which events
to match, and also as the event itself. Re-express these concepts
distinctly: an event is something that happened, an event_handler is the
predicate and name of the function to execute.
Prior to this fix, fish had a signal_list_t that accumulated signals.
Signals were added to an array of integers, with an overflow flag.
The event machinery would attempt to atomically "swap in" the other list.
After this fix, there is a single list of pending signal events, as an array
of atomic booleans. The signal handler sets the boolean corresponding to its
signal.
In a galaxy far, far away, event_blockage_t was intended to block only cetain
events. But it always just blocked everything. Eliminate the event block
mask.
