Prior to bb92edd1c802b521d766f46bf09b7e4b352f8398, it was impossible to test/work on any of these, as editmode bone drawing would not refresh at all when Copy on Write was enabled.
After this commit, all editbone operators should just work (COW isn't actually performed here now, since the edit bones list is just copied directly to the copies). Several of the operators have been tested (marked with *) and work fine, so we've marked all the others as working too. -- @Joshua Leung (aligorith) 2018/05/03

TODO: These still need checking by hand, as they don't necessarily operate on editbones
ARMATURE_OT_layers_show_all ARMATURE_OT_armature_layers- This updates as slowly with and without tweaks. But I've added an update tag for good measure ARMATURE_OT_bone_layers
