Otherwise it will be recognized only by the file extension, because
libmagic returns "application/octet-stream" as mime type. Moreover,
if the emf encapsulates a binary image format, it can be confused
with this other format and its preview on screen fails.
In such filesystems, including either Magic.h or magic.h does not
make any difference and the one or other file is included depending
on the search order. In this case, Magic.h was trying to include
itself instead of including magic.h.
This is not perfect, since variable width columns will break at a certain
treshold, but it is better than what we have now (no tabular width
indication at all)
When a raster image with an advertised pixel density different
from 72 dpi is included in a latex file, the output image dimensions
are scaled by the ratio 72/pixel_density. Hence, if a clipping
bounding box is specified, it has to be scaled by the same ratio,
otherwise the images will be clipped differently on screen and output.
Here we use the extractbb command (present in any TeX distribution)
to ask about the output dimensions of the image as dictated by the
pixel density and compute the scaling ratio by the knowledge of the
actual dimensions. If, for whatever reason, extractbb is not found,
everything goes as before, because the clipping bounding box will
simply not be corrected.

Cmake build: Simplify use of qt5 modules
According to this page:
http://doc.qt.io/qt-5/cmake-manual.html
the way to replace use of qt5_use_modules() for module "_mod" and target "_target"
is to use
1.) cmake_minimum_required(VERSION 3.1.0)
2.) find_package(Qt5${_mod} CONFIG REQUIRED)
3.) target_link_libraries(${_target} Qt5::${_mod})
The last one sets all reguired libraries, compile flags and needed includes for the ${_target}
Completion uses a complicated async scheme based on timers to update
itself. This is probably not necessary anymore and is fragile to
event order changes.
This is what happens with the new painting scheme. Therefore the
asyncHideXXX() methods have to be made more robust and detect whether
completion state has changed by the time they are triggered.
When an image has to be loaded a second time and the cache
is not used or the image is not in the cache, its preview is
going to be regenerated again. Hence, if the same image
appears more than once on screen, avoid requesting simultaneous
generation of the same preview.

This exception in the regex constructor is only theoretical (our regex
are hardcoded), but this is creating coverity noise.
Additionally, revert the following commits that are not needed anymore: 6b6fa94c: Catch exceptions to please coverity c2ed75fd: Fixup 6b6fa94c: coverity says there are more possible exceptions.

Cmake build: Adapt use of some variables
1.) Rename LYX_PATCH_VERSION to LYX_RELEASE_VERSION.
This matches the use in automake.
2.) Don't display LYX_DATE at configure time.
This value is evaluated later at build time
Skip paint event when in the middle of a buffer operation
This is detected when an undo group is open and contains at east one
element. This means indeed that changes are in progress. Note that the
group is in general opened in GuiApplication::dispatch. The code there
is changed to ensure that the group is closed before updating the
screen.
This patch is experimental. It is expected to be replaced in master by
a more complete solution. It could in the meantime be backported to 2.3.x.
As Kornel pointed out, it's possible to give a command sequence, or
multiple "-x" arguments, and carry out an operation without actually
giving LyX a filename argument. This will lead to cases like:
lyx -batch -x buffer-export
which don't do anything, but it's not catastrophic.
As of LaTeX2e 2018, characters are made active earlier, which results
in new expansion problems.
Following a suggestion of Markus Kohm (pc) and the TL mailing list [1],
we embrace non-ASCII input paths in \detokenize. This relies on e-tex,
but I think we can assume this is nowadays available everywhere.

Set caret height correctly for cells inside math rows
The code in 90cfe4ec3 only handled the cells which metrics are
computed directly, and missed those who were linearized inside a MathRow.
To fix this, we use the fact that all the positions in a math row have
the same height and make MathRow::metrics return a boolean indicating
whether it contains a caret for a given bufferview.
This is an extra command used for sidenote citations. Since we do not
provide \cite with natbib (which tufte uses) as a choice, we use the
new AddToCiteEngine feature to add it.
Allow for cite engine and format definitions/modifications in layouts
Now layout files and modules can extend the cite engines or completely
overwrite them, and modify the cite formats.
Any CiteEngine definition in a layout/module will completely overwrite
those by cite engine files.
AddToCiteEngine will extend them (add if they do not exist yet).
Any CiteFormat definition in a layout will be preferred to those in cite
engines. CiteFormat definitions that are not touched by the former are
still active, though (so, as opposed to CiteEngine, a CiteFormat does
not completely overwrite those by the engine files).
As opposed to modules (from which the framework was initially borrowed),
we only allow one cite engine per document. Thus, we don't need to fiddle
with lists.
This is like `layout', except that the layout is reset to default if
it was already correct. In the case of a selection, the layout is set
normally if some layouts in the selection are not at the required
layout; it is reset only if all the layouts of the selection already
have the required layout.

#11142 correct list of previous version to check for user directory contents
LyX on Mac uses a user directory with version suffix. On change of the version suffix the existence of the directories with previous versions is checked and the latest one is used for a copy on first configure run. For 2.4 the candidate list starts with 2.3 now as it should.
