This works around a TextMetrics issue where Row::beg/end_margin_sel
are sometimes not reset correctly when there is no selection on the
row.
In master a fix for this problem has been done at 654cded1. Here we
prefer a much simpler work around that fixes the symptom.
Fixes bug #10972.

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:
https://bugs.launchpad.net/bugs/1737429
The solution is to introduce BufferList::isInternal and act on it.
Fixes bug #10847.

since a few months MiKTeX's package manager required the option "--admin" when calling it with admin privileges
- also register the .lyx22 file extension to be opened with the future LyX 2.2.4
Instantiating a single QSettings and using it for each ui element
can significantly shorten the time required to save the various
states at exit. The speed up can be better appreciated on *nix,
where the settings are saved on disk, rather than on Windows where
they are held in memory (in the registry).
Add sips as a fallback converter for Mac to provide preview of PDF graphics in LyX when pdftops is not installed.

We need to invalidate the BibTeX cache when undoing or redoing. I do
not like having to do it for every undo or redo. We should only have
to do it if we restored or deleted an InsetBibTeX. But there is no
way, so far as I can see, to do it that way. I tried.

Since TeXLive 2016, "fontspec" maps the ligature break command
\textcompwordmark to the ZWNJ character (U+200C).
This character is missing in many fonts (including the default: Latin
Modern) which leads to "Missing character" warnings in the XeTeX/LuaTeX
log file if a document using non-TeX fonts contains a ligature break.
LyX reports missing characters as error since fixing #9610.
In case of "invisible" characters, there is no data loss, in case of the
ZWNJ the functionality is kept: ligatures are prevented also if the ZWNJ
is missing in a font.
Therefore, a missing ZWNJ is now treated similar to missing characters
in "nullfont" (see [63f41711/lyxgit], bug #10394) and does not trigger
an error.
Fixes: #10727
