This is a reimplementation of 6d4e6aad that is both simpler and more
complete.
This uses the updateBuffer mechanism to implement a fully working
version of Inset::isChanged(). Now the function returns true for an
inset that contains an inset that contains a change, for example.
Moverover Buffer::areChangesPresent() is merely a proxy for
Buffer::inset().isChanged().
Add Paragraph::isChanged() and InetText::isCgchanged() which indicate
the presence of a change in the relevant object.
Sets Row::needsChangebar() when adding an inset that contains changes.
Related to bug #8645.
Fixes part of #8469
For a proper fix that works with change-reject as well as with hide
changes in output, we need to implement
ct information in tabular's row and column.
If the file of an InsetInclude does not exist, loadIfNeeded will try
again and again to look for it. This is very bad for files with many
include insets, especially on windows.
Fixes bug #11656.
When used as an adjective, both variants "descendent" and
"descendant" are acceptable, but when used as a noun only
"descendant" should be used.

This crash occurred starting with 553bebc3, and can be triggered
when preview is enabled both in preferences and in a child document
inset. For a minimal example, see the following ML thread:

This fix restores behavior to before that commit for the case when
oldEnc is 0.
This is better than making sure that the inset has exactly one cell.
In the future, inset-dissolve could be extended to dissolve all the
cells contents in the enclosing text.
Note that this check does not appear in mathed, and using dissolve in
e.g. fraction inset may lead to data loss (only current cell contents
is preserved).
More complicated than I wished for, but color handling in RTL is
particularly tricky.
The three versions are needed due to the differences between [pdf]latex,
xetex, luatex/luabidi and luatex/babel.
Graphics "height" is only the height above the baseline and thus not
what most people will expect. Also, using height can result in a
division by zero with rotation.
Use totalheight now since this means "height of the figure" (independent
of the baseline).
The custom options field can be used if height is really desired.
We handle this in conversion/reversion, respectively, so document
output will not change.
Hence, file format change.
Fixes: #9676
