cooker: Ensure bbappend files are processed in a determistic order
self.appendlist is a dict and as such unordered. This can lead to cases
where appends with different names (e.g. x_%.bbappend vs. x_123.bbappend)
can be reordered in application which in turn reorders the variables
that those bbappend files might touch. Reorderd variables changes the sstate
cache signatures causing real world issues.
To avoid this, use a list for the append files instead.
This patch is conservative and just adds a new data structure alongside
the existing one and uses it to resolve the core issue. Later patches
(post release) can handle some of the wider but less problematic ones
(e.g. issues in bitbake-layers flatten).
