plotJittervsFill copies the -f argument into a 250-byte buffer with
strncpy(..., sizeof(LogFile)). A 250-byte file name leaves the buffer
unterminated, and the subsequent fopen() reads past the end of LogFile.
JitterTest uses the same fixed-size file name pattern for -r, while -c
still silently truncates overlong names and -f already rejects them.
Validate jittertest file name arguments before copying them so these
options all reject overlong input instead of truncating it or reading
past the end of fixed-size buffers.
Add a shell regression test that exercises the accepted and rejected
boundary lengths for plotJittervsFill and JitterTest during make check.

When passing a long argument, actually use labs().
The other case of passing a float to "int abs(int)" and
casting the result to an int doesn't really make sense.
Pull the cast inside the abs().

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.

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.
