GtkCssNumberValue is now a base class for numbers.
Actual numbers are now implemented in GtkCssDimensionValue. The name is
borrowed from the CSS spec, so there.
This is in preparation for calc(), as calc(50% - 5px) is valid CSS
but has 2 units. Instead, add a function to query a value's dimension
(so we can differentiate lengths from numbers) and add a function to
query if the value contains percentages.
Margins can be negative, and if we are not careful, then
content+padding+margin can end up with negative dimensions,
which can upset pixman and others. This commit ensures
that a gadget will not request or draw boxes with negative
dimensions, and get_border_allocation and get_content_allocation
will not return boxes with negative dimensions.
This fixes a crash in the paned separator drawing code that
can be reproduced by setting separator padding to 0.

With the location entry up in the header bar in save mode, we can
end up with the search model being in use when the user types in
the location entry. In this case, we don't make the Save button
sensitive as we should.
Having two entries in the dialog is somewhat confusing anyway,
so just stop the search when the user starts typing in the location
entry.

This reverts commit 572e9a0402.
_gtk_box_get_children was not doing exactly the same than
gtk_container_get_children does, because the latter uses the forall
implementation of GtkBox that takes into account the children pack mode while
the former just iterated the list of children. This broke the order of
the buttons in a GtkButtonBox when they were packaged with PACK_END.
Entries in treeviews and similar embedded situations don't really
work well if their height is forced to be big. Take out the min-height
for these.

It does no good to iterate through a series of mime types to call a
function when the eventually-called function,
_gtk_quartz_get_selection_data_from_pasteboard() in this case, gives the
wrong answer and stops the iteration on all but one especially if that
one isn't first.
The one is "image/tiff" and the quartz pasteboard function will return
any image type Quartz knows about for it, so lose the iteration and use
only "image/tiff".
A problem that has been observed in polari is that links in tags
are clickable all the way into the margin. This problem is caused
by gtk_text_view_get_iter_at_position ignoring the return value
of pango_layout_xy_to_index. Instead, pass it back as a boolean
return value. This is technically an API break, but we've allowed
ourselves to change return types from void to gboolean before.
