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

200 retries, not 100.
and open with O_NOFOLLOW and O_CLOEXEC
check X on mkstemp
support more than 6 X in mkstemp
make PATH_LEN 4096
1024 is a bit low
make default mkstemp length 4096

i had this idea in my head of later porting this
to k&r c for fun. but screw it.
compiling on everything since 1989 is enough

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
