a97faba653 init: use protobuf for serialization of persistent properties
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.

Test: init unit tests
Test: upgrade from legacy and intermediate property formats successfully

16fad42007 use a single file for storing persistent properties
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.

Bug: 64392887
Test: boot bullhead with new properties
Test: boot bullhead and verify old properties are converted to the new
      property file
Test: corrupt property file and ensure that it gets recovered from memory
Test: new unit tests
