Larger values will eventually crash LyX (see #12353), 0 or negative
values make the image disappear in the workarea and impossible to edit.

commit 14d63f5be8)
1/ The most annoying part was the error in po/. It turns out that reading
and understanding the po/Makevars file was the key. A simple change of
variable ensures that "make dist" does not try to rebuild lyx.pot.
2/ The way tests in src/ are defined meant that the
dependency-tracking files were not all deleted. This should be OK now.

QChar codepoints are 16 bit, so it is not wise to pass blindly a
char_type value to the QChar constructor.
Use the already defined isSpace() helper tht takes care of this issue.
Related to #12519, which is only known to bite with Qt6 for now; this
bug is thus theoretical in 2.3.
The minimal vamue is set to 10%, let's set the max to 1000%. This
avoids crashes when characters are too large.
The code is refactored to be more compact and the tests are more precise.
Fixes bug #12452.

Autoconf 2.71 now show all warnings. Instead of cherry picking the 2.4
patch, the choice was made to apply autoupdate directly.
Additionally, AC_INIT now clearly indicates that automake >= 1.14 is required.
In case of path names for external files containing symbolic links the real path
and the logical path name may be different for the same file or directory.
LyX is using QDir::tempPath() to create the path name of the temporary directory.
The Qt implementation is free to return the logical or the real path name here and
it happens to be different for various platforms and versions.
The most stable and clean solution is to use the real path name consistently.
