Subject: [PATCH v2] checkpatch: allow URL >80 chars

Allow URL to exceed the 80 char limit for improved interaction in
adaption to ongoing but undocumented practice.

$ git grep -E '://\S{77}.*' -- '*.[ch]'

The patch checks that the URL is indeed on its own line in that it
allows a maximal prefix of 3 characters to account for a URL after a
comment (e.g. '// https://...')

As per RFC3986 [1], the URL format allows for alphanum, +, - and .
characters in the scheme before the separator :// as long as it starts
with a letter (e.g. https, git, f.-+).

Recognition of URIs without more context information is prone to false
positives and thus currently left out of the heuristics.

$rawline is used in the check as comments are removed from $line.
