The algorithm used for breaking a paragraph in LaTeX export is changed
for avoiding spurious blank lines causing too much vertical space.
This change is tied to the introduction of a new inset (with two
different specializations) helping in either outputing LaTeX paragraph
breaks or separating environments in LyX. Both of the above goals were
previously achieved by the ---Separator--- layout and can now be
accomplished by the new inset in a more natural way. As an example,
after leaving an environment by hitting the Return key for two times,
a third return automatically inserts a parbreak inset, which is
equivalent to the old separator layout, i.e., it also introduces a
blank line in the output. If this blank line is not wanted, the
parbreak separator can be changed to a plain separator by a right
click of the mouse. Of course, an environment can still be separated
by the following one by using the Alt+P+Return shortcut (or the
corresponding menu key), but now the plain separator inset is used
instead of the old separator layout, such that no blank line occurs in
the LaTeX output.
Old documents are converted such that the LaTeX output remains unchanged.
As a result of this conversion, the old separator layout is replaced by
the new parbreak inset, which may also appear in places where the old
algorithm was introducing blank lines while the new one is not.
Note that not all blank lines were actually affecting the LaTeX output,
because a blank line is simply ignored by the TeX engine when it occurs
in the so called "vertical mode" (e.g., after an alignment environment).
The old ---Separator--- layout is now gone and old layout files using it
are also automatically converted.
Round trip conversions between old and new format should leave a document
unchanged. This means that the new behavior about paragraph breaking is
not "carried back" to the old format. Indeed, this would need introducing
special LaTeX commands in ERT that would accumulate in roundtrip
conversions, horribly cluttering the document. So, when converting a
modified document to old formats, the LaTeX output may slightly differ in
vertical spacing if the document is processed by an old version of LyX.
In other words, forward compatibility is guaranteed, but not backwards.
(unless it's already there, in which case it should move to the end of the next paragraph).
Change the preference setting name (mac_like_word_movement to mac_like_cursor_movement)
to better reflect its function.

Text.cpp:995: // LASSERT: Is it safe to continue here?
In the existing code for setting layout of pragraph parameters,
Text::undoSpan is used to "guess" which paragraphs should be saved in Undo.
With this patch the approach is more precise: before every explicit change
to a paragraph, a Cursor::recordUndo call is inserted. This is much more robust than trying to guess.
In particular, we do not look at depth changes at all, since they are now
handled in updateBuffer since #8159 has been fixed.
we will be cautious, of course). The problem was that we were issuing
the Buffer::changed() signal before we did updateBuffer(), and this
caused an inconsistency. The idea here is to defer issuing this signal
until we call processUpdateFlags(). We know we need a redraw if we've
deleted a whole paragraph.
This should work properly, so long as checkDepm is called from within
the dispatch mechanism. There may, however, be other paths, and I've
noted one explicitly with a FIXME in Text2.cpp. I've tested a few
different variations, however, and I haven't seen any problems. But if
we do run into problems, we can go ahead and do the update there that we
were previously doing in checkDepm itself.

- Interpret argument of LFUN_SPACE_INSERT correctly
- Use InsetMathSpace instead of InsetMathSpecialChar for "\ " (bug # 7728)
- Use InsetMathSpace instead of InsetMathChar for ~ (bug # 7728).
This fixes also the display in LyX (previously a literal ~ was displayed).
Using InsetMathSpace enables also the "Insert Formatting" menu entries.
No file format change is needed, since the LaTeX export is unchanged.
Note that there are still some bugs related to spaces in math:

DispatchResult to store a flag that tells us whether we need a buffer
update or not.
So: If you find a missing one, go to an appropriate place in the
dispatch and call cur.forceBufferUpdate() or, if you don't have a cursor
but do have a DispatchResult, call dr.forceBufferUpdate().
There is one remaining call I could not move, in
TextMetrics::redoParagraph. But this looks like an emergency call when
the macro context has not been set. There are also a couple calls that
are connected with buffer creation that I commented out, since the same
call is done again almost immediately. But I'm not positive about those.
Now the nice thing would be to do the same for updateMacros().

After executing DEPM to remove a double space, the position of the cursor was only 'fixed' if the cursor remained in the same par. This patch corrects this
to fix the position of the cursor also when the cursor is in a nested inset which is in the same par. This is needed because otherwise the cursor would not
point to the inset but one pos after it.

Specifically, moved the functions which actually move left or right from Text
into Cursor, and changed the semantics so that they now return whether or not
the cursor has moved. The functions in Text now use the new functions in Cursor.

The need for a LayoutPtr arises from the fact that (a) we do not want to give our clients a Layout &, since we do not want them to be able to change our Layout; but (b) we also need to be able to change which layout is ours. So we cannot store a Layout const &. Or so it seems to the compiler.

Sorry, Andre, but this broke not only the modules stuff but the general handling of TextClasses. I'm not opposed to doing this sort of thing, but it's going to be a little more complicated. I'll do it when I get a bit of time, or I can explain what the issue is here if you want to do it.
I'll separately re-commit some of the cleanup here.

Only when an LTR paragraph *ends with* an RTL chunk of text, movement was
incorrect in two ways:
1. After moving into the pargraph from the end, and then trying to move towards
the beginning of the paragraph, the cursor would immediately jump to the
previous pargraph.
2. If the cursor were placed inside the RTL text, and then we would move left
towards the beginning of the paragraph, upon reaching the end (beginning?) of
the RTL chunk, cursor would jump to the end of the paragraph, and then continue
as in (1).
(Same thing, of course, with the reverse situation, i.e., RTL paragraph ending
with LTR text).
We now deal with both of these cases correctly.

font, changes to the language were no longer being registered in the fontInfo,
and so we were wrongly under the impression that nothing had been changed.

This is the first patch in a series meant to remove LTR bias from the code.
Currently, there are many places in the code where "right" and "left" are used,
but where we actually mean "forward" and "backwards" --- which is the same
thing in LTR text, but not in RTL/Bidi text.
