This commit adds the mathed command \mathds that selects a
font more appropriate than \mathbb for typesetting the
mathematical symbols for the natural (N), whole numbers (Z),
rational numbers (Q), real numbers (R), complex numbers (C),
and some others.
As in the \mathbb case, only capital letters are supported,
but in addition one can also typeset a symbol often used for
representing the indicator function (\mathds{1}) and the
letters a, h, k.
Fixes bug #11887.
It turns out that the resources were mostly not used anyway. Removing
them shrinks LyX binary by ~6MB.
Only autotools have been adapted. cmake will require the same
simplification.
The automatic icons for "command-alternative", "math-insert",
"math-(big)delim" and "command" can be overriden by an explicit icon
name.
Besides that, the iconName function is refactored, and now returns an
additional bool that indicates whether the icon should be flipped.
The code that uses resources is still useless. This will be the
subject of further work.
74540c98 was a fixup of d207e85c, which avoided using inset background
as inset label background.
d207e85c introduced a background under inset labels to avoid fake bold
effect.
Hopefully, this last variation will be the right one !
This is a modern alternative for makeindex that is fully unicode-aware
and written in lua.
As opposed to xindy, it is more lightweight and actively maintained.
The program is still in a rather early stage of development, so we do
not propose this as default.
This relies on xindex 0.22 (about to be released) to function properly.
Due to a hint from Scott:

It seems that the use of zoom in determining the size of the minimal
value was a bad idea.
It still think that the situation is not very satisfying, we need a new idea.
The code was checking only for particular vertical alignment requests
in order to decide to nest a standard array into a 1x1 ams matrix.
However, also vertical lines are not possible in ams matrices.
These uses are inefficient (a loop really) and require that pit_type
is ptrdiff_t.
Instead, RandomAccesslist::constIterator is renamed to iterator_at and
a version adding a non-const iterator is added. Additionally, the
method retirns end() when position is equal to the size of the
container (see #11861).
lyx::next and lyx::prev are removed, and std::prev is used in the few
places where the code requires it (for no good reason IMO).
