[gforth] exit() code in main.c

[Bernd Paysan]

We have several places in main.c, where non-recoverable bugs happen, and we 
exit() on them. As Gforth can be used as library now, this is a bad idea - a 
library should never exit, so the only word that should be allowed to exit is 
main(). What to do?

C's exception handling with setjmp/longjmp is very poor, and can't be used 
outside the engine, where we pass the attempt to do some primitive exception 
handling to CATCH/THROW in Forth. So the probably best way is to define error 
return values for all the functions that may fail.
