"+" is part of sub-delims according to RFC 3986 and shall not be
converted to space.

ERL-316, as part of 19.3, adds the port number to the Host header
upon automatic redirection. The port number is included even if it
is a well-known port (80, 443). This is different from the
behaviour of most HTTP clients, as well as httpc's own for new
requests.

The added port number can lead to problems such as this one, where
the request signature assumes the client will not send the :443
suffix on redirection to an https URL:

I was unable to add a test case, since that would require a server
on a well-known port, but I manually verified that the GitHub/S3
signing issue was indeed resolved with this patch.

This supersedes PR #1185 (submitted by @KrzysiekJ) that changed
all occurrences of ref() with reference() in inets files.

However, there is little point in having these types only in comments.
So, these types are now exposed as type declarations for the record
fields they appear.  While at it, uncommented more commented out type
declarations and declared types for records defined in the affected
modules and header files.

Some type-unfriendly and obsolete code related to supporting code
ungrades with a really old OTP release was also removed.
