- The original flashcp process is erase, write and verify all blocks
in one time from file to device.
This patch will add a function that only copy different block data
from file to device. The function will compare blocks by block
between file and device, then erase and write block data from file
to device if found different block.

Sometimes there's a need to erase the whole device when
programming an image, and not just the area under the
image itself.
Therefore, option -A/--erase-all has been added which
erases the whole device before writing the image.

A common pattern in command line processing is having a usage()
function that prints out how to use the command line options and
then terminates.
The function is typically used inside a switch block for command
line options like `-h' or unknown options. In a lot of places, the
break keyword is omitted, because the function exits anyway. However,
this triggers gcc warnings about implicit fall-through.
Rather than adding a phony "/* fall-through */" this patch flags the
usage() style function with a gcc attribute, indicating that they do
not return and removes further superfluous break statements.

Add correct casting for filestat.st_size in flashcp.c. While the
interim status updates had correct casting from commit 08b243, the
final update was not.

When a program does sophisticated enough command line processing
(i.e. getopt), make sure it responds to -V and --version.
When a program prints a version string, make sure it uses the
common_print_version macro to print out its name, that it is part
of mtd-utils and the mtd-utils version from the build system in a
fashion similar to common program packages like the GNU coreutils.
When a program responds to -V/--version or -h/--help, make sure it
reports success exit status.

filestat.st_size type is off_t.
For some paltforms, off_t can be 32 or 64bit but there is no C99 format specifier for off_t.
The best way to print it with printf is to cast it to long long and print with %llu

* There is no code modification in this commit, only moving
* the files to proper place.
The user tools looks a little messy as we place almost
the all tools in the root directory of mtd-utils. To make
it more clear, I propose to introduce the following structure
for our source code.
mtd-utils/
|-- lib
|-- include
|-- misc-utils
|-- jffsX-utils
|-- nand-utils
|-- nor-utils
|-- ubi-utils
|-- ubifs-utils
`-- tests
