- Add error injection features to InMemoryFakeFlash. Reads or Writes can
be programmed to fail.
- Introduce key_value_store_error_handling_test.cc, which focuses on
corruption and read/write failure cases.
- Add functions for creating binary KVS entries at compile time.
Change-Id: Ie52ba5eb13eb60244835ef43314282beacc3a659
- Move EntryHeaderFormat and the EntryHeader struct to pw_kvs/format.h.
- Rename EntryHeaderFormat to EntryFormat.

- Switch from per-key versions to a monotonically increasing KVS-global
transcation ID.
- Move KeyDescriptor and the hash function to their own files.
Change-Id: I05287137579d4fe2d72c6e176969d46006c2aae6
- Move SectorDescriptor to internal/sector_descriptor.h.
- Make SectorDescriptor a class and move functions that don't reference
the sector descriptor map to it.

- 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.

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.

- Define the Output interface.
- Create AlignedWriter class, which handles writing aligned and padded
data to a buffer.
- Define AlignedWriterBuffer, which provides a buffer to an
AlignedWriter.

The pw::Vector class is similar to std::vector but is backed by a
fixed-size array. Using pw::Vector for descriptor lists cleans up the
code and makes iterating over these lists less error-prone. It also
opens the possibility of working with descriptor types that are not
default constructible.

- Move long-running Put test to a separate file.
- Do not dump the KVS state to file by default to prevent files from
showing up when the tests run.

- Add an 8-bit alignment field to the entry header. This makes the
entry header a complete description of the entry's representation in
flash (assuming the checksum algorithm is implied by the magic).
- Write basic tests for the EntryHeader class.
Change-Id: I7e48d5c16451ceb81f7c191d2f261e0a9bef14b7
- Make in_memory_fake_flash.h a separate library that is only visible
within pw_kvs (for now).
- Have the fake flash use PW_LOG_ERROR instead of the short names, since
it's logging from the header.

- Allow checksums to verify data larger than their internal state. This
facilitates using a CRC16 in a uint32_t.
- Move checksum functions to the EntryHeader class, since it ultimately
stores the checksums and is included with it.
- Enable one checksum test. Further tests are needed.
- Make some tweaks to the Get overload for objects.
Change-Id: I989b72905e140794f75c8f8619aaab1623f6f195
- Create CRC16 implementation of pw::kvs::ChecksumAlgorithm.
- Add tests for the ChecksumAlgorithm class.

Builds, but lots more work needed.
Fun fact: this code was written collaboratively in a Google Doc.

- Use std::string_view for keys to avoid the need for null termination.
- Use std::span and std::byte for data.
- Use StatusWithSize and size_t.
- Other minor adjustments.
