This is a follow-up of bug #8967. The implementation is self-explaining, the
only part which needs a comment is lyx2lyx: Since a 100% correct solution is
not possible, it has been decided not to switch amsmath off in the forward
conversion if no other ams command than \smash[t] and \smash[b] is used, but
to consider it a bug that older versions do not load amsmath automatically for
these commands. In the backward direction it is easy to keep the document
compilable, so just do that.
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.
lyx2lyx died with UnicodeDecodeError: 'ascii' codec can't decode byte if a
layout with a non-ASCII character in the file name was used, since the
textclass member of the LyX class was of type str, and not unicode.
Babel doesn't support this variant (yet), so we use ngerman. However, for spell checking and thesaurus, this makes
a difference.

been simplied, with working add and remove buttons. Note that bease BufferParams
lacks buffer path information, extraEmbeddedFiles are vector<string>, instead
of EmbeddedFileList (as previously planned).

The changes that accomplish this part are in ModuleList.{h,cpp}, configure.py, and the *.module files themselves. This is a format change, and the lyx2lyx is in those files.
By itself, that change would not be major, except for the fact that we do not want the module to be represented in the UI by its filename---e.g., theorems-std---but rather by a descriptive name, such as "Theorems". But that change turns out to be wholly non-trivial. The mechanism for choosing modules was the same as---indeed, was borrowed from---that in GuiCitation: You get a list of modules, and choosing them involves moving strings from one QListView to another. The models underlying these views are just QStringListModels, which means that, when you want to know what modules have been selected, you see what strings are in the "selected" QListView. But these are just the descriptive names, and we can't look up a module by its descriptive name if it's been translated. That, indeed, was the whole point of the change to the new representation.
So, we need a more complicated model underlying the QListView, one that will pair an identifying string---the filename minus the extension, in this case---with each item. This turns out not to be terribly difficult, though it took rather a while for me to understand why it's not difficult. There are two parts:
(i) GuiSelectionManger gets re-written to use any QAbstractListModel, not just a QStringListModel. This actually seems to improve the code, independently.
(ii) We then subclass QAbstractListModel to get the associated ID string, using the Qt::UserRole slot associated with each item to store its ID. This would be almost completely trivial if QAbstractListItem::itemData() included the QVariant associated with this role, but it doesn't, so there are some additional hoops through which to jump.
The new model, a GuiIdListModel, is defined in the files by that name. The changes in GuiSelectionManger.{h,cpp} make it more abstract; the changes in GuiDocument.{h,cpp} adapt it to the new framework.
I've also updated the module documenation to accord with this change.
