Certain applications may have their system properties overlaid with the
contents overlaid for appcompat purposes. Init must initialize the
appcompat folder, same as it does the standard folder.

v2 writer and v3 writer will write different versions of the header.
It's better to have each writer hold it's own header.

Adding Version 3 of CowHeader. This will inherit from original
CowHeader and add a compression field. We are no longer supporting
different compressions per operation so having this one field is enough.

We can shove type into source info to save 8 bits in per cow operation.
We only need 4 bits inside of source_info to enumerate all the types of
Cow Operation:
static constexpr uint8_t kCowCopyOp = 1;
static constexpr uint8_t kCowReplaceOp = 2;
static constexpr uint8_t kCowZeroOp = 3;
static constexpr uint8_t kCowLabelOp = 4;
static constexpr uint8_t kCowClusterOp = 5;
static constexpr uint8_t kCowXorOp = 6;
static constexpr uint8_t kCowSequenceOp = 7;
static constexpr uint8_t kCowFooterOp = -1;

Moving this function to cow reader first we have to read the version of
cow from the header before deciding which parser to use. This is a more
logical place for this code to be in

replacing any instance of op->source_info with GetCowSourceinfoData as
that's what we're really looking for. This function will return the 48
bits associated with the source and not the extra bits that will store
type + other information. We should never be making a reference to
op->source_info directly as that has no real meaning, we should be
masking for the data that we really need

This function will be called in header write for both v3 and v2 writer.
Seems okay to move to base class as theres no unique functionality to
the v2 writer.

We don't need the compression bit in v3 op since all operations will
have the same compression per COW Device and it will be stored within the COW header.
We can check to see if an operation contains compressioned data by
checking data_length and see if it's less than BLOCK_SZ

Adding v3 writer that works off of Cow Operation v3. Adding test file
that will test this new writer. Adding in stub implementations to v3 writer. None of these functions
have to work yet, we just need the implementations here to compile.

Currently we sleep for 5ms before decrementing retries for the last
time. This is a waste of time, so bail out of the loop if the last
rmdir attempt fails.

This code path was never invoked. is_logical will return false on
secondary partitions in retrofit devices, so nothing actually is ever
deleted. If we manage to call the delete, the device side code will
fail with "cannot open the super partition"
