  has large CHUNK_TYPE_FILL chunks

2c72404687 fastboot: sparse: implement reserve()
In order to process the CHUNK_TYPE_DONT_CARE properly, there is
a requirement to be able to 'reserve' a specified number of blocks
in the storage media. Because of the special handling of "bad blocks"
in NAND devices, this is implemented in a storage abstraction function.

9bc34799c8 fastboot: sparse: resync common/image-sparse.c (part 2)
- update fastboot_okay() and fastboot_fail()

This file originally came from upstream code.

While retaining the storage abstraction feature, this is the second
set of the changes required to resync with the
  cmd_flash_mmc_sparse_img()
in the file
  aboot.c
from
  https://us.codeaurora.org/cgit/quic/la/kernel/lk/plain/app/aboot/aboot.c?h=LE.BR.1.2.1

64ece84854 fastboot: sparse: remove session-id logic
This "session-id" alogrithm is not required, and currently corrupts
the stored image whenever more the one "session" is required.

c7529dbad1 fastboot: sparse: fix block addressing for don't care chunk type
When 7bfc3b1 (sparse: Refactor chunk parsing function) was implemented,
it dropped 9981945 (aboot: fix block addressing for don't care chunk type).

This re-implements the required fix for the "don't care chunk type"...

It may overflow in sparse_block_size_to_storage, use uint64_t instead in
the calculation.

3d4ef38de2 sparse: Rename the file and header
The Android sparse image format is currently supported through a file
called aboot, which isn't really such a great name, since the sparse image
format is only used for transferring data with fastboot.

Rename the file and header to a file called "sparse", which also makes it
consistent with the header defining the image structures.
