This introduces two new commands to the fastboot protocol:
- getvar snapshot-update-status - Return "none", "snapshotted", or
"merging" depending on the current status set by the boot control
HAL.
- snapshot-update [cancel] - Cancel any pending snapshot-based updates
via the boot control HAL. After this, the HAL should return
MergeStatus::CANCELLED and "update-merge-status" should be "none".
If no argument is specified, the snapshot-update-status is returned
via an INFO response.
Bootloaders are expected to implement this in a manner consistent with
the boot control HAL.
Fastboot-based tooling should expect wipes of userdata to fail when
update-merge-status returns "merging". Thus, the force flag now cancel
any pending snapshots.

load_buf_fd() attempts to find the size of the file that it is about
to load by first calling sparse_file_import_auto() then using
sparse_file_len() upon success or falling back to the file size on the
filesystem on failure.
This is problematic however as sparse_file_import_auto() creates a
sparse_file out of the normal file, but does not resparse it, so an
assertion fails during the sparse_file_len() call.
This is fixed by using sparse_file_import() instead. This will fail
in the case that the file is not sparse and the call to
sparse_file_len() will be properly skipped.

Currently, during a 'fastboot flashall/fastboot update', the 'getvar

bootloader mode and the same value is used even after the device boots
into fastbootd. If the max-download-size returned by bootloader is
greater than the max-download-size in fastbootd, this could break flash
as large images are broken down into chunks before downloading by using
the max-download-size variable. This will cause fastbootd to return
an error since it checks whether the buffer being downloaded has a size
greater than the max-download-size limit.

As part of a refactor, commit db511207ed
added a timeout for receving responses for commands. Unfortunately,
the timeout is optimistic as to how quickly target devices can complete
such operations. Flash and erase commands can be quite slow on devices
with traditional flash chips. The fastboot protocol is already adept
at handling such cases because it allows for sending INFO packets during
these periods. We may receive one or more INFO packets during tehse long
operations. Every time we receive an INFO packet, it proves the remote
end is alive, but busy, which should reset our timeout timer.

On retrofit devices, if both slots contain dynamic partition builds,
then "flashall" will attempt to write secondary images to dynamic
partitions in the other slot. At worst, this can fail with an error. At
best, it will result in the "other" partition not being mounted on first
boot.
This patch therefore deletes logical partitions for secondary images, on
retrofit devices only. On a Pixel device on the "b" slot, this means
"system_a" and "vendor_a" will be deleted before flashing, and therefore
system_other and vendor_other will be flashed to physical partitions
instead.

Retrofit devices will have two super partitions, spanning the A and B
slots separately. By design an OTA will never cause "A" or "B"
partitions to be assigned to the wrong super. However, the same is not
true of fastbootd, where it is possible to flash the inactive slot. We
do not want, for example, logical "system_a" flashing to super_b.
When interacting with partitions, fastbootd now extracts the slot suffix
from a GetSuperSlotSuffix() helper. On retrofit devices, if the partition
name has a slot, that slot will override FastbootDevice::GetCurrentSlot.
This forces partitions in the inactive slot to be assigned to the correct
super.
There are two consequences of this. First, partitions with no slot
suffix will default to the current slot. That means it is possible to
wind up with two "scratch" partitions, if "adb remount" is used on both
the "A" and "B" slots. However, only the active slot's "scratch" will be
visible to the user (either through adb or fastboot).
Second, if one slot does not have dynamic partitions, flashing will
default to fixed partitions. For example, if the A slot is logical and B
is not, flashing "system_a" will be logical and "system_b" will be
fixed. This works no matter which slot is active. We do not try to
upgrade the inactive slot to dynamic partitions.

On retrofit devices, it is easy to accidentally overwrite
system/vendor/product by flashing system in the bootloader. The reason
is that GPT system_a is really the super partition, and the bootloader
doesn't know it.
Addressing this in bootloaders would require two separate commands: one
that rejects flashing system/vendor/product, and another for
expert/factory use that would allow direct flashing.
This patch introduces protection into the host fastboot tool instead.
It's not mutually exclusive with bootloader changes; having protection
in the host tool affords us better and consistent UI. However it does
rely on users having newer builds.
With this change, the following will not work in the bootloader:
fastboot flash system # or vendor, product, etc
The message is the same whether or not the device is a retrofit. To
continue anyway, you can do:
fastboot flash --force system
If we decide on bootloader protection as well, the --force flag can be
re-used.

fastboot flashing tool has been updated to query this variable.
Since the super partition name can no longer be determined without

dynamic partition support rather than the presence of a super partition.

The purpose of this code was to support preserving partitions across a
flashall operation. Since we are not supporting persistent read-write
partitions, this merging code is effectively useless - it is preserving
only partitions that will be deleted.
Additionally, this code does not merge partition group changes, since
doing so accurately is difficult. Partition size changes aren't sent
until after update-super resolves, so a valid re-grouping could be
rejected during update-super if the existing partitions are too big.
This patch removes the update-super merging code until a use case comes
along and we can properly evaluate how it should work.

After rebooting to userspace fastboot, the first command issued is
"update-super". If we wound up in the bootloader by accident (as
happened to a few users with a busted vbmeta_system), the resulting
error message will be very misleading ("update-super" will be an
unrecognized command).
Instead, this patch explicitly errors if we did not successfully boot
into fastbootd.
Bug: N/A

This allows us to remove libziparchive's dependency on libutils.
Bug: http://b/79112958
Test: ran libbase and libziparchive tests, ran fastboot manually

Cleanup to utilize all the manifest values in constants.h.
If the cli command _and_ the protocol name match, use a common
source of convenient truth. This should set a pattern for future
additional commands. When the command and the protocol differ,
we want to introduce resistance as it results in confusion and
maintenance issues.
Test: compile

Sparse images with CRC are not supported by the Android build
system and hence the calculated CRC is unused.

Boot control HAL implementations will return the current boot
slot as the active slot. If a set_active command is issued on another
slot, it should be considered as the new active slot and subsequent
flashes should flash the same.
Test: fastboot set_active "b", fastboot getvar current-slot

This is required to pass fuzzy_fastboot conformance tests.
Also, allow for zero sized partitions in fuzzy_fastboot.

If a device has logical partitions but does not use a partition called
"super", we will need this to be configurable. Note that the "slot"
argument is currently unused, but will be necessary for update_engine if
there are A and B super partitions.
Bug: 116608795
Test: super partition works

Replace the remnants of engine.cpp with better functionality in
FastBootDriver. Particularly, add prolog() and epilog()
callbacks to FastBootDriver for printing actions and their result to
the console. Then clean up the rest of fastboot.cpp to directly use
FastBootDriver.
Test: fastboot works

CheckRequirements() had various issues that are cleaned up here,
1) Move from C string parsing to C++
2) Moved from C data structures to C++, including fixing memory leaks.
3) Removed the 'cur_product' global and the 'query_save' function that
stores it
4) Actually writing tests for the parsing function for
android-info.txt
5) Check that a variable needs to be checked for a given product before
trying to read it. Previously, fastboot would fail if a variable
isn't recognized on a device, even if the check should be ignored.
A lot of flexibility is allowed for the input strings, to keep
backwards compatibility with the previous parsers.
Test: fastboot works, unit tests
