This patch restructures various code parts that follow the pattern
of "stat(x, &sb) ... makes_sense(&sb) ... open(x)".

This patch eliminates warnings generated by the -Wmissing-prototypes
option. With this flag set, we are now forced to have prototypes for
all global, exported functions, that have to be made visible to the
definitions and we are forced to mark all local functions as static.

Several tools are simply not checking return code of functions marked
with 'warn_unused_result'.
Provide wrappers for the read/write functions to avoid patching old
code and providing proper error handling.
Fix the remaining ones (calls to fgets() and system()).

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
