This can lead to cases<br>
where appends with different names (e.g. x_%.bbappend vs. x_123.bbappend)<br>
can be reordered in application which in turn reorders the variables<br>
that those bbappend files might touch. Reorderd variables changes the sstate<br>
cache signatures causing real world issues.<br>
<br>
To avoid this, use a list for the append files instead.<br>

This patch is conservative and just adds a new data structure alongside<br>
the existing one and uses it to resolve the core issue. Later patches<br>
(post release) can handle some of the wider but less problematic ones<br>
(e.g. issues in bitbake-layers flatten).<br>
