* Let isValidHost() determine validness of host
- PHP way of doing so (https://github.com/php/php-src/pull/826)
- Improved and shortened regexp a bit
* Give more specific debug message in case host(entry) is invalid
* Rewrite filter_var checks
* Host [[<ipv6>]] is not valid
* Always Q-encode headers exceeding maximum length
Previously, headers exceeding the maximum line length without
any special characters were only folded. This lead to problems
with long filenames (#1469) and long headers in general (#1525).
Now, long headers are always Q-encoded (and still folded).
* Use ASCII as Q-encoding charset if applicable
Previously, headers were Q-encoded using the message
charset, e.g. UTF-8. This is excessive for ASCII
values, as it requires a unicode engine.
Now, we use ASCII if we only find 7-bit characters.
* Separate header encoding from encoding selection
* Use ASCII for B-encoding as well
* Refactor max line length calculation
Previously, we calculated the maximum
line length for header encoding both
for B- and Q-encoding, even though
they share the same limits.
Now, we calculate these once for both.

Upgrade guide and changelog say that idnSupported() is now static, but it actually isn't.
Probably this PR should wait v6.1 or other version where breaking changes are OK.
