Jakob Borg 0d2fe320a7 cmd/stvanity: New utility to create vanity device IDs
A potential practical use is to encode a short version of the hostname
at the beginning of the device ID.

For example:

	jb@syno:~/s/g/s/s/c/stvanity $ stvanity abc
	Want 15 bits for prefix "ABC", about 3.3e+04 certs to test (statistically speaking)
	Found ABCFPWS-JKDIFV3-E5IUAQW-DK53WVR-HY7XWBS-56H33GR-CJQI67Q-VGXRMAW
	Saved to cert.pem, key.pem

	jb@syno:~/s/g/s/s/c/stvanity $ stvanity $(hostname)
	Want 20 bits for prefix "SYNO", about 1e+06 certs to test (statistically speaking)
	Trying 554 certs/s, tested 8307 so far in 15s, expect ~32m total time to complete
	Trying 543 certs/s, tested 16277 so far in 30s, expect ~32m total time to complete
	...

The rest is just a matter of patience.

	jb@syno:~/s/g/s/s/c/stvanity $ stvanity syncthing
	Want 50 bits for prefix "SYNCTHI-NG", about 1.1e+15 certs to test (statistically speaking)
	Trying 529 certs/s, tested 7941 so far in 15s, expect ~67443 years total time to complete
	...
