Many tools open a file descriptor, close it a the end and have some
form of error path in between that jumps to the end.
In some cases, if opening the file fails the error path is taken and
the utility ends up closing one or more invalid file descriptors. It's
technically not a real issue but something that pretty much any static
analysis tool barks at.

The --skip-bad-blocks-to-start option will increase the seek offset by the
size of each bad block encountered between the start of the partition and
the specified start address.
This can be useful when writing part way through a partition that will be
read using a simple bad-block-skipping algorithm.

JFFS2 supports clustering erase blocks to virtual erase blocks.
nandwrite supports this, but previously mixed up virtual and
physical erase block numbers when checking for bad blocks.
This patch adds a function for checking if a virtual erase block
is bad and replaces the broken mtd_is_bad loop.

This patch makes sure that a virtual erase block is always
composed of a postivie number of erase blocks (i.e. 1 or more)
and enforces the block alignment to be a power of two as
suggested by the help text and assumed throughout the program.

Pull the buffer content checking code into separate function and
simplify the code invoking it slightly.

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.

* 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
