[RFC] x11 / cairo-less build try #3

[Riccardo Magliocchetti]

Hello,

this is another update on building libreoffice without need to link
against X11 or toolkits in general. The aim is to ease the deploy
server side where less dependencies needed the better.

As you can see the vcl/headless/headlessinst.cxx has been shamelessly
copied from Android, you can see still some #if 0-ed code because i'd
like to have soffice.bin run without crashing to assure myself that the
code is not needed :)

The salplug changes probably are not needed anymore, the #if 0 in
tests are asserts that does not look regressions i've introduced.

Michael i've not forgot about cleaning up Library_vcl.mk :)

Now that everything builds at runtime it fails at runtime, looking
around cli_ure/source/climaker/climaker_app.cxx:476 does not show something obvious, any hint?
