This is a host based tool wherein it compares two Android images and generates snapshot patches which are similar to Android OTA format.
There are few advantages:
1: All the computation of snapshot logic is pushed onto the host.
2: Each partition can have different compression algorithm.
3: All the libsnapshot_cow changes can be tested very quickly.
Here is the test run. This compares two builds which are 24 hours apart.
```
create_snapshot --source=$ANDROID_PRODUCT_OUT/system.img --target=./images/system.img --compression="zstd" &
create_snapshot --source=$ANDROID_PRODUCT_OUT/product.img --target=./images/product.img --compression="lz4" &
create_snapshot --source=$ANDROID_PRODUCT_OUT/vendor.img --target=./images/vendor.img &
create_snapshot --source=$ANDROID_PRODUCT_OUT/system_ext.img --target=./images/system_ext.img --compression="gz" &
create_snapshot --source=$ANDROID_PRODUCT_OUT/vendor_dlkm.img --target=./images/vendor_dlkm.img &
echo "Waiting for snapshot patch creation"
wait $(jobs -p)
echo "Snapshot patch creation completed"
```
========================================
Waiting for snapshot patch creation
Snapshot patch: vendor_dlkm.patch created successfully
Snapshot patch: vendor.patch created successfully
Snapshot patch: system_ext.patch created successfully
Snapshot patch: product.patch created successfully
Snapshot patch: system.patch created successfully
Snapshot patch creation completed
real 0m3.848s
user 0m14.239s
sys 0m8.045s
========================================
It takes ~4 seconds to generate the snapshot patches on the host. Snapshot patches are named as <partition-name>.patch.

aosp/2734054 added socket timeouts for nonblocking liblog ops.
seccomp policy was not updated so tests failed when unallowed

The command will be used by RMA tool to skip
device wiping when it is already in GSI mode.
This change also makes it easier to add more
gsi commands in the future without needing to
update the host side tool (fastboot).

Test: 1. reboot into fastboot mode
2. fastboot gsi status

It is not necessary to compare the dumps with the library installed in

Existing code has transport memory leaks. Use smart pointers
for transport to get rid of those cases and manual memory
management
Test: atest fastboot_test
Test: manually checked transport isn't leaking anymore

Adding a test case for checking if flash task is a dynamic partition
flash task. This function is used since is-logical only works in
fastbootd, and should_flash_in_userspace() only works if
$ANDROID_PRODUCT_OUT is set. This function works with fastboot update
when called in bootloader without $OUT dir set
Test: fastboot_test

Adding documentation on the explicit pattern match we are going to add
to optimizing flash super.

Adding test cases for correct formation of optimized flash super task.
We are adding an explicit pattern match for this task to be correctly
formed. Changing Optimized flash task to only remove the reboot to
userspace as a user might want to reboot back to bootloader after
flashing. We also need to change a couple functions to take a
IFastbootDriver to mock up the initialization path.

Adding a hard pattern check for optimized task formation. To keep
behavior consistent, we will remove the old initialization path and add
resize tasks after attempting optimization.
