Foot previously responded with window local coordinates.
But, XTerm responds with screen *absolute* coordinates. This isn’t
possible under Wayland, thus we now report (0,0) instead. Same as we
do for ‘CSI 13 ; 0 t’.
It’s ok to let the receiving end handle formatting C0 control
characters in bracketed paste mode.
In fact, we *must* let them through. Otherwise it is impossible to
paste e.g. tabs into editors and similar applications.

When ‘selection-target’ is set to ‘none’, selecting text does not copy
the text to _any_ clipboard.
This patch also refactors the value parsing to be data driven.
In addition to letting the FDM do the low-level signal watching, this
patch also fixes a bug; multiple SIGCHLDs, be it delivered either through a
signal, or via a signalfd, can be coalesced, like all signals.
This means we need to loop on waitpid() with WNOHANG until there are
no more processes to reap.
This in turn requires a small change to the way reaper callbacks are
implemented.
Previously, the callback was allowed to do the wait(). This was
signalled back to the reaper through the callback’s return value.
Now, since we’ve already wait():ed, the process’ exit status is passed
as an argument to the reaper callback.
The callback for the client application has been updated accordingly;
it sets a flag in the terminal struct, telling term_destroy() that the
process has already been wait():ed on, and also stores the exit
status.
Add fdm_signal_add() and fdm_signal_del(). Signals added to the fdm
will be monitored, and the provided callback called as “soon as
possible” from the main context (i.e not from the signal handler
context).
Monitored signals are *blocked* by default. We use epoll_pwait() to
unblock them while we’re polling. This allows us to do race-free
signal detection.
We use a single handler for all monitored signals; the handler simply
updates the signal’s slot in a global array (sized to fit SIGRTMAX
signals).
When epoll_pwait() returns EINTR, we loop the global array. The
callback associated with each signal that fired is called.
