Showing deleted display math by enabling "Show Changes in Output" was
only possible with dvi (through dvipost). Although LyX strikes out
such formulas on screen, it was impossible obtaining an output
directly using pdflatex (or other engines producing pdf) because
ulem cannot cope with display math material and gives errors.
The solution is to strike out by ourselves such deleted formulas.
I took into account several options. One of them would produce
an output similar to dvipost (which strikes out each element), but
would have required much more changes in the output routines.
Eventually, I opted for using tikz, which gives a more clean
output (as it requires to simply adding a preamble and a postamble
to the latex code of any displayed math, instead of a mark up
tailored to each particular math construct). The look of the pdf
output is similar to the way LyX strikes out the equations on screen.
This enables error reporting for the preamble, provided the preamble is written
using the new InPreamble layouts.
In the future, I find it preferable to deprecate the usual preamble in favour of
InPreamble layouts rather than implementing error reporting for the usual
preamble. This requires some improvements to code editing in the buffer view
first (line breaking behaviour, syntax highlighting).
It was broken in two ways: It was not threadsafe, and it did never detect
any recursion, since the counter was decremented for each non-recursive call
and never incremented again.
Normally, we do not load babel when English is the only language. However, if we check if babel is used from Font::validate, we need to surpass this test, else no secondary language is registered if English is the main language.
Of course this will only work if output_changes was true when creating the
.tex file.

Now you can also require a|b|c, and if any of the features is already used,
no other one will be loaded. The first feature wins if none is already used.
This is required for a part of bug #7811.

We might want to rename the babelpreamble tokens to something more general.

This allows us to remove some ugly hardcoding of languages in the source.

borrow the LatexFeatures::addPremableSnippet() method to do it.

bring it into line with the handing of Layout's preamble and requires. This
will make information about used InsetLayout's avaiable elsewhere.

Don't go into an endless loop if layout2layout cannot produce the desired file format.

Later, this can be replaces by a backpointer approach, as proposed at bugzilla (note that there are already similar cases such as InComment or InTableCell, so a backpointer approach would need to adapt the OutputParams methos anyway).

* Layout.h:
- name_, obsoleted_by_, depends_on_ are now docstrings.
All other changes results from the above string -> docstring changes. In particular, we now try to translate the layout names only if possible (i.e. if they are ASCII only).

Introduces new encodings for the CJK-languages.
The CJK-languages can now be selected from LyX's menu.
For remaining small problems, see the thread "Help needed for bug 3043" on the devel-list.

* src/buffer.C (validate): adapt to change below.
* src/lyxtextclass.C (read): replace tags ProvidesNatbib,
ProvidesMakeidx, ProvidesUrl and ProvidesAmsmath by a generic
"Provides".
(provides): take a string as argument.
* lib/scripts/layout2layout.py (convert): convert "ProvidesXxx" tags
to "Provides xxx".

* src/LaTeXFeatures.[Ch]
(LaTeXFeatures::addExternalPreamble): rename to addPreambleSnippet,
since this is not specialized for InsetExternal at all
