Refactor properties macro, improve errors

clippy cleanup

Greatly improve `clone!` proc macro error output

gio: make ListModel::iter() infallible

Panic if the wrong type is requested, this is more ergonomic and

macros: support overrides in the properties macro

Support `default = ...` in the properties macro

Use strcmp for GStringPtr comparisons

This avoids one level of indentation

For performing utf-8 checks on a pointer.

properties: correctly type check value returned by the getter fn

gio: implement FromIterator for ListStore

Fixes https://github.com/gtk-rs/gtk-rs-core/issues/951

Rename GStrPtr to GStringPtr

The conversion requires calculating the length so it is expensive and
should be explicit.

Since this is an owned type this is more consistent.

This improves the assertion failure as otherwise it would just assert on
the wrong type if a `NU...

These methods return an owned StrV, but also provide the length,

Rename StrVItem to GStrPtr and make it clonable and transparent

Add TransparentPtr marker trait to List, SList and StrVItem

It is useful to have also in cases different from StrV, for instance

List and SList are wrappers around C pointers

Fixes https://github.com/gtk-rs/gtk-rs-core/issues/922

They're `GTimeVal` relative to the UNIX epoch in C and not a plain
duration.

It's a duration in milliseconds or -1 and the `Impl` trait already used
an `Option<Duration>` here.

build-tools: Allow passing multiple source dirs to `compile_resources`

You can pass the command line tool multiple source dirs, so we should
