`UUID` generally stands for "universally unique identifier". The session identifier that we use is neither universally unique, nor does it follow the standard. Therefor, the term "session uuid" is confusing and should be replaced. In #116888 we briefly talked about a better name and ended up with "session uid". The reason for "uid" instead of "id" is that the latter is a very overloaded term in Blender already. This patch changes all uses of "uuid" to "uid" where it's used in the context of a "session uid". It's not always trivial to see whether a specific mention of "uuid" refers to an actual uuid or something else. Therefore, I might have missed some renames. I can't think of an automated way to differentiate the case. BMesh also uses the term "uuid" sometimes in a the wrong context (e.g. `UUIDFaceStepItem`) but there it also does not mean "session uid", so it's *not* changed by this patch.
