When building for homebrew/linuxbrew on Ubuntu 16.04, memfd_create() is
not available and causes the build to fail.
This adds a proper check for the function.
When reading text, we need to check we terminate the G_TYPE_STRING
string with a null byte, because the clipboard does not guarantee one.
So just append a \0 to the stream.
Fixes#3899
Just from reading the code, it seems that we
should unset .csd and .solid-csd at the same
time, since the are mutually exclusive and
we unset them here so realize() can set one
of them again.
The code in gtkwindow.c for dealing with the various
combinations of client-side decorations and client-side
shadows is entirely too complicated.
This commit does not really clean it up, but simplifies
one of the shadow conditions far enough to make some
sense.
With this change, I get the expected decorations in
all the cases I can easily reproduce locally.
Deriving the resize border size from the shadows
carries the risk that we might end up with uneven
resize borders (or none at all, on some sides).
So, justs enforce that we have a big enough shadow
width on all sides.
Previously it was impossible to compose characters on higher levels of
some keyboard layouts as pressing the level selection key would just
exit compose mode.
Examples for affected keyboard layouts include the Latvian
apostrophe-variant "lv(apostrophe)" (latched third level), the extended
German keyboard layout "de(e1)" (latched fifth level) as well as the
multilingual Canadian keyboard layout "ca(multix)" and the German
neo-layout "de(neo)" and its descendants (shifted fifth level).
To reproduce, set a compose key and select the Latvian apostrophe layout.
Notice that you now can input [ by pressing first the ' and then the 8-key.
Then pressing <compose>'8'8 should produce ⟦, but prior to this patch it
did not.
The invisible resize borders have been wider than they
should, for a while. Go back to a size close to what
we have in GTK3.
To summarize: resize borders will be at most 12 pixels
on each size, but never wider than the windows shadow.
The resize corners have 'legs' of 24 pixels where you
still get a corner resize cursor.
Fixes: #3856
Only send selection-changed events when we either
had a non-empty selection before, or have one now.
This should help orca speak the right things, and
not the wrong things.

Orca relies on these to keep track of the focus location,
ignoring the focused state. With this change, orca can
once again speak text in entries as I type.
We are starting with a pretty empty a11y object tree,
and we want orca to bring more of it into existence
by navigating the tree. But that only happens when we
send it events. Primarily focus events, which come in
from GTK via the platform_change mechanism. So realize
the context when we are sending platform_changes,
otherwise, orca never gets the mesage.
