- Reorder entry_test.cc and add an additional test for Copy.
- Add comments to key_value_store_map_test.cc.

Fix garbage collection when using redudant entries.
- Improve "find sector to write entry to" and "find sector to GC"
algorithms so they work better with redundant entries.
- Add support in GC to be aware of partially written keys, where the
first entry is written to flash, but GC is needed to free space for
the redundant entries to have space to be written.
Tested with kEntryRedundancy up to 2.

Add support to KVS for storing multiple identical copies of key-value
entries.
Currently only tested for kEntryRedundancy = 1.

- Add public methods to do full garbage collect and partial garbage
collect.
- Do clean up related to finding sector to write entry to that is in
preparation for adding redundancy support.

- Move EntryHeaderFormat and the EntryHeader struct to pw_kvs/format.h.
- Rename EntryHeaderFormat to EntryFormat.

- Test calling Init() at random points.
- Test using only two sectors and using many smaller sectors.
- Delete tests that will never work, since alignments must be a multiple
of 16.

- Switch from per-key versions to a monotonically increasing KVS-global
transcation ID.
- Move KeyDescriptor and the hash function to their own files.

Move the KeyDescriptor and SectorDescriptor lists to a templated derived
KeyValueStoreBuffer class. This allows multiple KVSs supporting
different numbers of keys and sectors to exist side-by-side.

- Update comments for FlashMemory class.
- Split InMemoryFakeFlash to move the fixed-size buffer into the
derived FakeFlashBuffer class.
- Support initializing FakeFlashBuffer to data provided at construction.
- Allow direct access to the underlying fake flash buffer for testing.
- Create utilities for working with byte arrays in byte_utils.h.
Change-Id: I90d33621cb91da079d7213fe7d33823494120e48
- Add the FlashPartition and address to the Entry class.
- Move functions for reading or writing the entry header, key, and value
to the Entry class.

When moving tombstone entries for deleted keys, RelocateEntry would
cause them to become present again.
Expand key_value_store_map_test.cc and add a test that covers this case
specifically.

Introduce a system for writing tests against flash memories with
different parameters. The tests use a std::unordered_map as an oracle,
and all operations are checked against it. Invalid inputs and the KVS
filling up are handled.
Disable most of the tests because they are currently failing.
