e6b78e5d56 lib/rand: Break out random functions into separate package
The intention for this package is to provide a combination of the
security of crypto/rand and the convenience of math/rand. It should be
the first choice of random data unless ultimate performance is required
and the usage is provably irrelevant from a security standpoint.

6d11006b54 Generate ECDSA keys instead of RSA
This replaces the current 3072 bit RSA certificates with 384 bit ECDSA
certificates. The advantage is these certificates are smaller and
essentially instantaneous to generate. According to RFC4492 (ECC Cipher
Suites for TLS), Table 1: Comparable Key Sizes, ECC has comparable
strength to 3072 bit RSA at 283 bits - so we exceed that.

There is no compatibility issue with existing Syncthing code - this is
verified by the integration test ("h2" instance has the new
certificate).

There are browsers out there that don't understand ECC certificates yet,
although I think they're dying out. In the meantime, I've retained the
RSA code for the HTTPS certificate, but pulled it down to 2048 bits. I
don't think a higher security level there is motivated, is this matches
current industry standard for HTTPS certificates.

64354b51c9 Generate certs with SHA256 signature instead of SHA1
Doesn't matter at all for BEP, but the same stuff is used by the web UI
and modern browsers are starting to dislike SHA1 extra much.
