spoiler alert: it's slow as molasses
part 2 will be presented at a later date
(yes, please don't fill 8GB of memory with
random data and hexdump it)

the functions no longer return errors, so i don't
need to handle them.
furthermore, the handling in state.c is redundant,
so i've removed that too.

generalise it in rand.c because this logic will
be useful for other programs in the future.

this is a more generic one that i implemented
for "lottery.c" (which is really just a tester
of my rset function in lib/rand.c)
i could probably actually write a full hexdump
program in libreboot-utils to be honest.

i now use a singleton hook function per program:
nvmutil, mkhtemp and lottery
call this at the startup of your program:
(void) errhook(exit_cleanup);
then provide that function. make it static,
so that each program has its own version.
if you're writing a program that handles lots
of files for example, and you want to do certain
cleanup on exit (including error exit), this can
be quite useful.
