The previous fix for parsing IPv6 URLs with a zone index was a paddle
short for URLs without an explicit port. This patch fixes that case
and adds a unit test case.
This bug was highlighted by issue #3408, and while it's not the full
fix for the problem there it is an isolated bug that should be fixed
regardless.
Closes#3411

If just a `?' to indicate the query is passed always store a zero length
query instead of having a NULL query.
This permits to distinguish URL with trailing `?'.

A URL with a single colon without a portnumber should use the default
port, discarding the colon. Fix, add a testcase and also do little bit
of comment wordsmithing.

This adds a new unittest intended to cover the internal functions in
the urlapi code, starting with parse_port(). In order to avoid name
collisions in debug builds, parse_port() is renamed Curl_parse_port()
since it will be exported.

An IPv6 URL which contains a zone index includes a '%%25<zode id>'
string before the ending ']' bracket. The parsing logic wasn't set
up to cope with the zone index however, resulting in a malformed url
error being returned. Fix by breaking the parsing into two stages
to correctly handle the zone index.

The function does not return the same value as snprintf() normally does,
so readers may be mislead into thinking the code works differently than
it actually does. A different function name makes this easier to detect.

APPENDQUERY + URLENCODE would skip all equals signs but now it only skip
encoding the first to better allow "name=content" for any content.

The function identifying a leading "scheme" part of the URL considered a
few letters ending with a colon to be a scheme, making something like
"short:80" to become an unknown scheme instead of a short host name and
a port number.
Extended test 1560 to verify.
Also fixed test203 to use file_pwd to make it get the correct path on
windows. Removed test 2070 since it was a duplicate of 203.

... and libcurl doesn't support any single-letter URL schemes (if there
even exist any) so it should be fairly risk-free.

Fixes#3070Closes#3071
In order for this API to fully work for libcurl itself, it now offers a
CURLU_GUESS_SCHEME flag that makes it "guess" scheme based on the host
name prefix just like libcurl always did. If there's no known prefix, it
will guess "http://".
Separately, it relaxes the check of the host name so that IDN host names
can be passed in as well.
Both these changes are necessary for libcurl itself to use this API.

In the CURLUPART_URL case, there is no codepath which invokes url
