This commit fixes a couple of warnings from Qt 5.14 like the
following one:
error: ‘int QTime::restart()’ is deprecated: Use QElapsedTimer instead [-Werror=deprecated-declarations]
This commit changes two uses of QTime to QElapsedTimer, one used
only when the "files" debug flag is set, and the other for timing
whether a script (e.g., knitr) takes longer than a certain amount of
time to run.
QElapsedTimer is superior for these two use cases in that it uses a
monotonic clock if possible, and is thus more robust to certain
changes (e.g., daylight savings changes) [1]. Similarly, the commit
in Qt Base that makes this deprecation [2] mentions the following in
the commit message:
QElapsedTimer does the job better and without the DST kludges.
Note that QElapsedTimer class was introduced in Qt 4.7, so no
conditioning on Qt version is necessary.
Not all methods of QTime are deprecated and we still use some of
the non-deprecated methods in our code (e.g., to get the current
wall clock time in GuiProgress::currentTime()).

The log file generated by latex can contain strings encoded in
whatever supported encoding. Instead of guessing the encoding,
it is better to open it in binary mode and then performing the
necessary comparisons as "bytes". In order to do this, the
strings are encoded in utf8, so that, for example, b"pythön" is
encoded as "pyth\xc3\xb6n" (7 bytes). Of course, this means that
we can only successfully perform comparisons with ascii strings.
However, this is what we actually do, as we only search for
ascii strings in the log file.
Thus a document can be viewed if it contains references to
its master, children or siblings that are being excluded via includeonly,
or viewed standalone if it contains references to its master or siblings.
Using a dialog may trigger a redraw at times where the metrics caches
have not been updated yet. To fix this, do as in paintEvent() and
abort caret blinking if there is an open undo group.
Move the decision to skip the caret painting to showCaret(), closer to
where real work happens. hideCaret () is now an alias for
showCaret(false), which allows some code refactoring.

Fixes bug #11763 (although it does not trigger on master).
This is a mode for includeonly handling that is effective and still outputs
at least mostly correct counters and references. This is intended for non-
final editing work.
File format change.
GuiInclude::initialiseParams() calls InsetCommand::string2params()
which calls InsetCommandParams::clear(), however this last function
did not reset the special "preview_" parameter. Now this parameter
is reset to false as part of clear().
The ParamData class documents (see InsetCommandParams.h) the
following:
// No parameter may be named "preview", because that is a required
// flag for all commands.
Thus, we must handle preview_ separately from the other parameters.
This commit fixes#11779.
First, we do not need to run bibtex/biber on the maintenance run, as
the necessary references will be generated on the includeonly run.
Second, exclude the master from DepTable in maintenance run, as the
master is re-checked in any case in the includeonly run, and as it will
always be detected as changed due to the \includeonly statement, which
will trigger a complete build.
More improvements to follow.
There is no need to change the cursor's position to the beginning of
the line.
This change does not affect the behavior of using the buttons in the
Outliner pane, but is useful for using the keyboard shortcuts.
Fix warnings coming from deprecations of QTextEdit::tabStopWidth()
and QFontMetrics::width(). Regarding tabStopWidth(), the ChangeLog
states the following [1]:
Introduced tabStopDistance property in QTextOption, QTextEdit and
QPlainTextEdit as replacement for the inconsistently named tabStop and
tabStopWidth properties. QTextOption::tabStop, QTextEdit::tabStopWidth and
QPlainTextEdit::tabStopWidth are now deprecated.
Note that QFontMetrics::horizontalAdvance() is what we want here, as
opposed to QFontMetrics::boundingRect(), because we want to know
where to draw the next character after the tab.

Fix the following warning from Qt 5.14.1:
error: ‘static bool QPixmapCache::find(const QString&, QPixmap&)’ is deprecated: Use bool find(const QString &, QPixmap*) instead [-Werror=deprecated-declarations]
Fix the following warning from Qt 5.14.1:
error: ‘static QList<T> QList<T>::fromSet(const QSet<T>&) [with T = QString]’ is deprecated: Use QList<T>(set.begin(), set.end()) instead. [-Werror=deprecated-declarations]
Regarding QList::fromSet(), the documentation now states the
following [1]:
Since Qt 5.14, range constructors are available for Qt's generic
container classes and should be used in place of this method.

Fix the following warning:
error: ‘void QFileDialog::setConfirmOverwrite(bool)’ is deprecated: Use setOption(DontConfirmOverwrite, !enabled) instead [-Werror=deprecated-declarations]
Note in the change that "false" changes to "true" because the option
is *Dont*ConfirmOverwrite.
QFileDialog::setConfirmOverwrite() is obsolete at least since 4.8
and QFileDialog::setOption() is available since 4.5 [1].

Fixes the following warning:
error: ‘void QWidget::getContentsMargins(int*, int*, int*, int*) const’ is deprecated: use contentsMargins() [-Werror=deprecated-declarations]
The new code also has advantages in that 'l' can be set to const and
it is more readable because it is clear that only 'l' is used.
QWidget::getContentsMargins() was deprecated in 5.14.0 [1]. and
QWidget::contentsMargins() is available since 4.6 [2].
