- increase the size of the fill buffer
- testing has shown a 10x improvement when the sparse image
has large CHUNK_TYPE_FILL chunks

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.

- 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

This "session-id" alogrithm is not required, and currently corrupts
the stored image whenever more the one "session" is required.

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"...

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.
