The former getopts segment gave impression unknown options will
cause the program to exit with error and help is available with
-h. Neither work quite as designed, all unknown options made the
program to exit with success; and none of the options where
known.
The fix also has support for long options, and new --version
switch.

Moving the malloc out of loop will make leak to disappear, and
the command might run few jiffie quicker when there are 1+N
arguments.

Solaris lacks err, errx, warn and warnx. This also means the err.h header
doesn't exist. Removed err.h include from all files, and included err.h from
c.h instead if it exists, otherwise alternatives are provided.

* Change indentation to 8 characters and coding style, for better reading the code.
* Add some memory allocation error handling.
* Fix memory leaks. In cases when Ctrl-C is used to exit the program,
'p' cannot be freed, so made it a global var, to share between main()
and sig_handler(). Signal handing is necessary to fix some leaks, so
added a very basic, non invasive, mechanism.

The function warn() in rev.c is actually duplicate code,
so here we remove it.
