[fontloader] node injector / december 3 sync

Hi Hans,

from the huge changeset two weeks ago:

     +texio.write_nl("The font code has been brought in sync with the context version of 2014.12.01 so")
     +texio.write_nl("if things don't work out as expected the interfacing needs to be checked. When")

-- Message received ;) First off, thanks for bringing the
fontloader into sync again. So far I haven’t noticed any
obviously broken features.

However, something is off with the node injector. We have a bug
reported by Hironori Kitagawa that occurs with the ``palt``
feature in node mode:

    http://tug.org/pipermail/luatex/2014-November/004976.html

Importing the shiny new font injector into the merged fontloader
fixes the issue. FWIW here are test files

    https://bitbucket.org/phg/lua-la-tex-tests/src/tip/cnt-features-12-palt.tex
    https://bitbucket.org/phg/lua-la-tex-tests/src/tip/pln-features-12-palt.tex

The Context version runs fine whereas the plain one does so only
after my “fix”. The same is true for Context itself: replace
font-inj.lua with node-inj.lua in the format to reproduce the
issue. Is there a fix to the fontloader, perhaps only temporarily
until the revised injector becomes ready?

Best,
Philipp

not really as the new injector does more ... also, the new code is kind 
of beta so it might not be a good idea to use that in latex already ... 
i'm still working on some issues with disc nodes and fonts that have 
ligatures that are not ligatures

so, i'd first like to do more tests here; of course you can use the new 
injector if you want ... (i'm not touching generic now while messing 
with the context variant)

The current goal is to add an option to load the code directly
from Context (TL, minimals). Right now this is non-trivial due to
the extra packaging step involved, so the option will facilitate
testing a lot. Let’s see if anyone is confident enough to test
the fontloader on their own if it becomes easier.

Just running my tests ;) I’m fairly content with the prospect
that the issue is already addressed in the beta.
