When doing the lyx2lyx round trip of the 2.0.8 user guide from format
413 -> 474 -> 413 you get an invalid document, because the math packages
mhchem and undertilde are incorrectly converted.
It turned out that the old reversion code did only work for particular
package oderings. The new one works for abitrary sorted packages.

When doing the lyx2lyx round trip of the 2.0.8 user guide from format
413 -> 474 -> 413 you do not get a zero diff. The most important problem is
caused by the conversion of the argument insets to the old syntax: This
conversion adds an additional empty line (harmless), and it destroys the
document structure if the first inset in e.g. a subsection is not an argument
inset, but e.g. an index or label inset.
The fix is quite easy: Ensure that the paragraph begin is set to the first
argument inset.

revert_justification() issues a warning if the \justification parameter does
not exist, and LyX itself always writes it unconditionally as well, so add it
also in lyx2lyx when converting old documents.
Currently this does not have any user visible effect, but it decouples the
default value of BufferParams::justification from the conversion of old
documents: Now it is possible to set the default to false in LyX, and old
documents will still be converted correctly.

The code that checks whether the cursor was at the end of a row in
Cursor::upDowninText was not able to set boundary correctly. This
causes a hang in because the cursor got stuck on a line and there is an
infinite loop BufferView::dispatch when trying to go down.
The fix is to avoid using the watered-down TextMetrics::x2pos wrapper
around getColumnNearX and use the real thing instead.
Eventually, the last user of x2pos (InsetTabular) should be fixed and
the method should go away.
