This is a fixup for `align-self`, the computed value of which should now
properly inherit `align-items` value of its parent. Additional passed
tests is also removed from ini folder. Fixup for geckolib errors.
Add the remaining longhand CSS properties of flexbox for servo,
including `flex-wrap`, `flex-grow`, `flex-shrink`, `justify-content`,
`align-items`, `align-self` and `align-content`.
tests for the remaining longhand properties are also enabled. Test for
default value of `align-self` is modified because the new default value
for this property is "auto" is current flexbox CR.
While we're here we also:
* remove any code conditional on style_struct.gecko_ffi_name, since all
style structs now do have a corresponding Geckos struct
* add new UIReset and XUL style structs, so that all Gecko structs are
now present (apart from Variables, which is special)
Sorry for the bulk size of this; I know already it's not going to be a fun thing to review. Nevertheless, it should be done so we finalize the split of this huge file into smaller, more maintable parts.
The content of stuff being moved to separate files is unchanged. Only some minor formatting changes have been made and similar, but nothing of particular interest. IMHO it should be safe to merge if all the tests are fine.
This is a new attempt of #10586, after Simon Sapin's great cleanups in #10749 has landed. I have adjusted the changes to the new structure that was introduced, and also only done a few of the longhand ones. Will certainly continue on this as soon as we have a basic agreement that this style is reasonable.
