Rework watchlist
...
Watchlist is now read from ~/.certspotter/watchlist by default, or from
the file specified by -watchlist (- for stdin).
By default, only exact DNS names are matched. To match both the domain
itself and all sub-domains, prefix with a dot (e.g. .example.com).
Comments are now allowed in watchlist files.

Tighten up the cert information output
...
Remove subject and SANs since they are redundant with earlier identifier
listing. Remove serial number because who cares? Put type of entry
on same line as log entry info.
If people want this info they can always examine the saved file or the
crt.sh page.

Only replace DNS label with placeholder if it's utterly unparsable
...
e.g. contains control characters, Punycode conversion fails
There are quite simply too many certs with bogus DNS labels out in the wild,
and it just doesn't make sense to bother every .com domain holder because
GoDaddy signed a cert with a DNS name like "www. just4funpartyrentals.com"
It is highly unlikely any validator will ever match that DNS name.

Additional handling of pathological DNS names

1. Trim leading and trailing whitespace of DNS names.
2. Trim http:// and https:// prefixes.
3. If DNS name contains a slash, ALSO process the DNS name up to
the first slash, since it's probably a URL.

...
IDNs can be specified in either Unicode or ASCII (as Punycode).
Certs can specify the DNS name either way, and we'll match it.

If a UTF8String in the Subject CN isn't valid UTF-8, or if a DNS SAN is
not ASCII, raise a parse error, since we don't know how to interpret
the string.

Save consistency proof along with evidence of misbehavior
...
Although the consistency proof is neither necessary nor sufficient
to prove misbehavior by a log, this will help with debugging if a
log returns a bogus consistency proof erroneously (which seems to
be happening with the Rocketeer log lately...).

Make trailing garbage a fatal error when extracting DNS names
...
Logging something to stderr was not helpful, and it's best to be
on the safe side anyways.
Whitelist a single null byte following the SAN extension. This
is a harmless and common error.
As of now, all certificates in the CT logs parse successfully.
