Summary: During the previous attempt to generalize the UUID class, it was suggested that we represent invalid UUIDs as length zero (previously, we used an all-zero UUID for that). This meant that some valid build-ids could not be represented (it's possible however unlikely that a checksum of some file would be zero) and complicated adding support for variable length build-ids (should a 16-byte empty UUID compare equal to a 20-byte empty UUID?). This patch resolves these issues by introducing a canonical representation for an invalid UUID. The slight complication here is that some clients (MachO) actually use the all-zero notation to mean "no UUID has been set". To keep this use case working (while making it very explicit about which construction semantices are wanted), replaced the UUID constructors and the SetBytes functions with named factory methods. - "fromData" creates a UUID from the given data, and it treats all bytes equally. - "fromOptionalData" first checks the data contents - if all bytes are zero, it treats this as an invalid/empty UUID.
