I probably should have done this from the start... There's a shim to
convert my manually serialized format to protobuf, and since that has
not yet shipped, it'll be reverted in a short period of time.

We have seen that storing persistent properties in separate files
causes increased boot latency compared to if they were stored in a
single contiguous file.
This change creates a simple format for a contiguously stored property
file, and adds the support for arbitrary characters in the names of
persistent properties, which previously had been restricted. It has a
mechanism for converting older devices to the new format as well.
