This might eliminate some false positives being thrown by Coverity to
do with the return value of `uri_decoder()` and whether it’s allocated
anything.

Make `G_URI_FLAGS_PARSE_RELAXED` available instead, for the
implementations which need to handle user-provided or incorrect URIs.
The default should nudge people towards being compliant with RFC 3986.
This required also adding a new `G_URI_PARAMS_PARSE_RELAXED` flag, as
previously parsing param strings *always* used relaxed mode and there
was no way to control it. Now it defaults to using strict mode, and the
new flag allows for relaxed mode to be enabled if needed.

According to my reading of
https://tools.ietf.org/html/rfc3986#section-4, the only requirement for
a URI to be ‘absolute’ (actually, not a relative reference) is for the
scheme to be specified. A hostname doesn’t have to be specified: see any
of the options in the `hier-part` production in
https://tools.ietf.org/html/rfc3986#appendix-A which don’t include
`authority`.

This reduces the possibility for overflow, and makes the code a little
more conventional to read.

`guint8` is the conventional way in modern GLib APIs to represent ‘a byte
which could contain arbitrary binary’. `guchar` is not advised for that
(even though it’s equivalent) because it could be misread as `gchar`.

This reduces the chance of the caller accidentally double-freeing or

Sometimes there are sensitive details in URI query components, so we
should provide the option for hiding them too.

This brings its naming in line with the ‘generic’ error codes in other
error domains.
This is not an API break since `GUriError` hasn’t been in a release yet.

RFC 3986, section 3 says:
> The scheme and path components are required, though the path may be
> empty (no characters). When authority is present, the path must
> either be empty or begin with a slash ("/") character. When
> authority is not present, the path cannot begin with two slash
> characters ("//"). These restrictions result in five different ABNF
> rules for a path (Section 3.3), only one of which will match any
> given URI reference.
(See https://tools.ietf.org/html/rfc3986#section-3.)
Given that those conditions are almost always going to be true, and that
typically the number and form of arguments passed to g_uri_join() will
be known at compile time, it would be unnecessarily awkward to add a
`GError` argument to g_uri_join() to detect these situations.
Instead, add precondition checks and document the restrictions.
Developers are responsible for ensuring their paths are in the right
format themselves.

The g_uri_join_internal() function was making a simplification that
userinfo can be encoded with the same restricted character set as the
user field alone, fix this by allowing the correct character set.

Otherwise, the to_string() encoding will not be reversible. Furthermore,
if no distinction is needed in the first place, g_uri_build() with
userinfo should be used instead.

g_uri_build_with_user() builds a userinfo, but it shouldn't encode it
itself, but let the user flags declare what's there. Otherwise,
to_string() code paths may encode a second time.

Add encoded flags, similar to what was done in commit 7bee36b4 ("uri:
add G_FLAGS_ENCODED_QUERY").
SoupURI has manual handling of encoded path & fragment, but it can rely
on GUri decoding for the rest.

GTK ci rightly complains about this when ti builds
GLib as a subproject with -Werror=maybe-uninitialized.
subkey_dynamic_w will be freed without being initialized
when the first goto is taken.
The heuristic is a bit too agressive, as we may have hostname with
%-encoded ':' (as shown in GVfs URI tests).
Add an extra test to check :-decoding as well.

Add a few ipv6 scope parsing corner test cases.
- checking incorrect scoped IPv6 ending with only %25 isn't decoded.
- checking valid scoped IPv6 is passing g_uri_is_valid()
As discussed in
https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1567#note_860499,
for historical reasons, GUri accepts the % preceding the zone-id in the
unescaped form as well.

g_uri_is_valid() should check the given URI is valid following RFC-3986,
and reject relative references.
