The current internal meanings of "locked", "user_locked",
"qmp_locked", "frozen", "enabled", and "disabled"
are all
a little muddled.
Deprecate the @status field in favor of two new booleans
that carry very specific meanings. Then, rename and rework
some of the internal semantics to help make the API a bit
more clear and easier to read.
Well, in my opinion.
Based on my current bitmaps branch.
V3:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
