Up to [DVB] / dietlibc

shave off a few bytes from parselib by removing the exit code from
__prepare_parse, which was not used anyway because you could see whether
it worked by looking at the struct state afterwards.  Uwe Ohse noticed
this.
Also, fix asprintf, which relied on vsnprintf to not write anything when
passed a NULL pointer.  This was no longer the case after Olaf redid the
printf engine.
