If somehow we wind up with snapshots with a source suffix, we could wind
up trying to unmap an in-use partition. Detect this case and allow the
snapshot to be deleted without the unmap.

To improve boottime, we want to run odsign in an asynchronous fashion;
but there are 2 places where we do need it be sync:
1) We need to know when it's done using its key, so that we lock
keyrings and advance the boot stage
2) We need to know verification is complete before we start the zygote
These are indicated by odsign using separate properties.
Bug: 165630556
Test: init waits for the properties, and proceeds when done

Use sorted std:vector instead of std:map to store
the mapping between chunk-id to COW operation.
Addtionally, use shrink_to_fit to cut down vector
capacity when COW operations are stored.
On a full OTA of 1.8G, Anon RSS usage is
reduced from 120MB to 68MB. No variance observed
when merge was in progress.

When a user issues `fastboot flash vendor_boot:foo ramdisk.img`, the fastboot driver
fetches the vendor_boot image from the device,
determines if `foo` is a valid vendor ramdisk fragment,
repacks a new vendor boot image, then
flash the vendor boot image back.
This requires vendor boot header V4.
As a convinent alias, `fastboot flash vendor_boot:default ramdisk.img`
flashes the whole vendor ramdisk image. This works on vendor boot header
V3 & 4.

The `fastboot fetch` command is a wrapper around
the fetch protocol. It:
- getvar max-fetch-size
- get the size of the partition
- read the data by chunks, chunk size = max-fetch-size.
The name of the partition is passed directly to the device
(with the usual has-slot magic for flashing etc.) If we support
fetching partitions other than vendor_boot in the future, no change
in the driver is needed.

fastboot_buffer owns the fd. Make ImageSource::Open()
returns a unique_fd and pass ownership all the way
down to the fastboot_buffer to avoid leaking fds.

O_CLOEXEC ensures fastbootd does not leak fds to the parent
process (recovery).
O_BINARY has no effect in Linux, but it is explicit that
the file (partition) to read is a binary file.
