err if buf NULL, len -1
also getrandom may return fewer bytes, so
loop that too.
why can't linux be like bsd? bsd is:
arc4random_buf(buf, len);
no checks needed. it never errs.

openbsd 2.1 has arc4random, which we detect here.
arandom was apparently added much later, so this
is dead code. remove it.

we still fall back to the old /dev/urandom read
on older linux, via runtime detection (ENOSYS).
getrandom is better, because it guarantees entropy
via blocking, and works even when /dev/urandom
is unavailable.
it has the same practical benefit as arc4random,
which i use on bsd. linux can have arc4random,
but not every linux libc has it, so it's better
to use getrandom on linux.
older linux will fall back to /dev/urandom

also generally tidied the code and made
it more robust e.g. retries

handle init in xstatus()
it's now a singleton design
also tidied up some other code
also removed todo.c. bloat.
will do all those anyway.
too much change. i just kept
touching the code until it
looked good
