Waiting for the client application to terminate can take a noticeable
amount of time.
If we do this in a foot --server instance, we’ll be blocking other
footclient instances from processing any kind of events, including
Wayland events.
As an example, on a tiling WM with two footclient windows next to each
other, closing one of them _may_ cause the other window to be
resized (by Sway), before foot has been able to provide a properly
resized surface, resulting in the old (non-resized) surface being
centered in a too-large window by Sway.
This patch moves the whole client termination business from
term_destroy(), to term_shutdown(). This means it now runs *before*
the Wayland window is unmapped. This should allow other footclients to
respond in time once the window *is* unmapped.
If the call to fdm_wayl() with EPOLLHUP was followed by calls to
wayl_roundtrip(), foot would hang.
The reason for this is that the EPOLLHUP handler in fdm_wayl() would
call wl_display_cancel_read().
wayl_roundtrip() also calls wl_display_cancel_read() (since we
normally have called wl_display_prepare_read()), before calling
wl_display_roundtrip().
When calling wl_display_cancel_read() two times in a row, without a
wl_display_prepare_read() in between, wl_display_roundtrip() hangs.
Fix by not calling wl_display_cancel_read() in fdm_wayl(). This
ensures our invariant holds: wl_display_prepare_read() is *always* in
effect outside of fdm_wayl().

We still use the primary font, but use a custom size, based on the
title bar’s height.
This fixes an issue where the window title could be way too small, or
way too big. And changed size when the terminal font size was changed.
Set clip region in render_osd(). This ensures we don’t step outside
the pixman buffer when rendering the glyphs.
Furthermore, don’t ignore the alpha channel in the background color.
Move render_osd() to make it visible to the render_csd_*() functions.
While we’re in scrollback search mode, the selection may be
cancelled (for example, if the application is scrolling out the
selected text). Trying to e.g. extend the search selection after this
has happened triggered a crash.
This fixes it by simply resetting the search match state when the
selection is cancelled.

Add stubs for shm_chain_new(), shm_chain_free() and shm_unref(). This
fixes ‘pgo’ linking failures in the ‘generate’ phase when doing a PGO
build with clang.
Closes#642
