Fix compiler warning in the iv-editor module.
Supress the compiler error for elua_uip.c for now.
This file has references to luaL_xxx functions.

Now, we have to figure out a way to get the code
to work for PicoC (and all the other languages
Alcor will support). This might be a bit of work.
We'll get back. For now, the code for PicoC on Alcor
compiles without issues (without uip).

Let's check if this actually works on the Mizar32.
CPPdefined BUILTIN_MINI_STDLIB and PICOC_LIBRARY.
This is enabled when the tiny ram optimizations are
disabled (optram = 0)
Changed the default shell prompt to Alcor.
Got rid of compiler errors. Now, I can see PicoC run on
the Mizar32 in optram=0 mode.

Of course, this file requires cleanup (a lot of it) but
we'll get to that a bit later.
Disabled UIP for now. We'll get back to this file when
we've introduced and tested optram=1.
This version of iv.c and iv.h for Alcor (modified iv-0.39)
is buggy. A reasonably tested version of modified iv-0.39
will replace these files.
Updated iv* files. Tested with PicoC on Alcor with
optram=0 configuration. Some cleanup required. Check
on TODO's.
