sslutil: issue warning when [hostfingerprint] is used...

sslutil: issue warning when [hostfingerprint] is used Mercurial 3.9 added the [hostsecurity] section, which is better than [hostfingerprints] in every way. One of the ways that [hostsecurity] is better is that it supports SHA-256 and SHA-512 fingerprints, not just SHA-1 fingerprints. The world is moving away from SHA-1 because it is borderline secure. Mercurial should be part of that movement. This patch adds a warning when a valid SHA-1 fingerprint from the [hostfingerprints] section is being used. The warning informs users to switch to [hostsecurity]. It even prints the config option they should set. It uses the SHA-256 fingerprint because recommending a SHA-1 fingerprint in 2017 would be ill-advised. The warning will print itself on every connection to a server until it is fixed. There is no way to suppress the warning. I admit this is annoying. But given the security implications of sticking with SHA-1, I think this is justified. If this patch is accepted, I'll likely send a follow-up to start warning on SHA-1 certificates in [hostsecurity] as well. Then sometime down the road, we can drop support for SHA-1 fingerprints. Credit for this idea comes from timeless in issue 5466.
