Since CheckTeX itself processes the tex file, a synchronous run with
a TeX process can lead to all sorts of conflicts, including crashes.
Fixes: #7434.
The issue here was that the element was only removed from the queue
after the func request was processed, but within that process, other
function could access the queue, so the queue could even be empty
when this function finally wanted to remove the item.
Fixes: #10406.
A brand new event compressor based on Kuba Ober's cleverly simple
solution: <https://stackoverflow.com/a/21006207>.
Fix#9362, #9461, #9933: Lyx suddenly gets keyboard keys wrong, and
deadlocks
Fix#9790: LyX should perform key event compression (for improving the
remote X connections one would also need to implement
Qt::WA_KeyCompression)
Fix#10516: slowness on repeated arrow keys with IBus and Qt5

It is not good for a support function to depend of anything outside of
it, especially Application.
Here the boolean that indicates that export should be canceled is put
in Systemcall. This allows to remove all the dummy theApp() function
that have been added here and there for linking needs.
This gets rid of the hardcoded latin1 encoding for verbatim. Instead,
verbatim now inherits the encoding from the context, which is what is
actually wanted here.
Fixes: #9012, #9258
This had the effect that for file dialogs supposed to use two buttons,
only the second one was displayed, while file dialogs supposed to use
one button did not have a button at all.
Candidate for 2.3.x and 2.2.x.
Qt on macOS does not respect the Qt::WA_OpaquePaintEvent attribute and
clears the widget backing store at each update. Therefore, we use our
own backing store in this case.
This restores a simplified version of the code that was removed at 24c29908.
Now the helper class contains logic that checks whether buffer are
known before closing them. This avoids potential crashes.
Use it in different places to siplify code. It is not clear at this
point whether it should be used everywhere.
Followup to bug #10847.
When a buffer is in an embedded work area (adv. find&replace), it is
not found by BufferList:::exists(), and therefore the undo group
created in GuiApplication::dispatch and in the handling of
LFUN_COMMAND_SEQUENCE will not be closed.. Crashes can ensue, as
described in Ubuntu bug:

The solution is to introduce BufferList::isInternal and act on it.
Fixes bug #10847.
