Here's an 'mcookie' implementation for toybox.
mcookie simply prints out 16 bytes of entropy in hexadecimal; it is typically
used as the source for the "MIT magic cookies" that X11 uses for "secure"
connections.
The only implementation I know of is in util-linux; the problems with its
documented behavior motivated me to write an alternate implementation.
Specifically, getting 128 bytes from the kernel and finding the MD5 sum is
not a sane PRNG, especially when only 16 bytes are needed.
